The patch implements the idea suggested by Olaf van der Spek in 
thread "Client: many small reads?" (internals@lists.mysql.com).
Now small reads performed by the client library are buffered.
The buffering gives up to 2 times speedup when retrieving 
one-column tables.

vio/vio.c:
  Optionally set up vio read buffer when creating a new VIO structure.
vio/viosocket.c:
  Implementation of client-side buffered reads in VIO: the idea 
  is to buffer small reads in a client buffer to save amount of
  syscalls per retrieved result set. The implementation relies
  on the fact that read/recv will return as soon as there is
  some data in the kernel buffer, no matter how big the given
  user's buffer is. To be able to disable it in case recv/read don't
  have such semantics, the new calls are guarded
  with #define HAVE_VIO_READ_BUFF. Currently buffered reading is 
  switched on only for BSD sockets and named pipes, both on Windows
  and UNIXes.

sql/ha_innodb.cc:
  write_row(): Detect SQLCOM_OPTIMIZE, so that also OPTIMIZE TABLE
  will commit at every 10,000 copied rows.

and some SP-related cleanups.

- We don't have separate stage for calculation of list of tables
  to be prelocked and doing implicit LOCK/UNLOCK any more.
  Instead we calculate this list at open_tables() and do implicit
  LOCK in lock_tables() (and UNLOCK in close_thread_tables()).
  Also now we support cases when same table (with same alias) is
  used several times in the same query in SP.

- Cleaned up execution of SP. Moved all common code which handles
  LEX and does preparations before statement execution or complex
  expression evaluation to auxilary sp_lex_keeper class. Now 
  all statements in SP (and corresponding instructions) that
  evaluate expression which can contain subquery have their
  own LEX.

  sp_merge_hash():
   Now uses its return value to indicate that first of two hashes changed

  sp_cache_routines():
   This function caches all stored routines used in query now.
sql/sp.h:
  - sp_find_procedure() now has one more parameter which enforces cache only
    lookup.
  - sp_merge_hash() now uses its return value to indicate that first of two
    hashes changed as result of merge.
  - sp_cache_routines() caches all stored routines now. So it does not need
    third argument any more.
sql/sp_head.cc:

  sp_head::execute():
   Let us save/restore part of thread context which can be damaged by
   execution of instructions.
  sp_head::execute_function()/execute_procedure():
   Now it is responsibility of caller to close tables used in
   subqueries which are passed as routine parameters.
  
  sp_head::restore_lex():
   Let us accumulate information about routines used by this one
   in new m_spfuns, m_spprocs hashes.
  
  sp_lex_keeper::reset_lex_and_exec_core()
   Main method of new auxilary sp_lex_keeper class to which instructions 
   delegate responsibility for handling LEX and preparations before
   executing statement or calculating complex expression.
  
  Since all instructions which calculate complex expression or execute
  command now use sp_lex_keeper they have to implement
  sp_instr::exec_core() method. Most of instruction specific logic
  has moved from sp_instr::execute() to this new method.
  
  Removed sp_instr_set_user_var class which is no longer used, because
  nowdays we allow execution of statements in stored functions and
  triggers.
  
  sp_merge_table_list() became sp_head::merge_table_list() method. It
  also treats sp_head::m_sptabs as multi-set of tables now.
  
  sp_hash_to_table_list() became sp_head::add_used_tables_to_table_list().
  It takes into account that sp_head::m_sptabs is multi-set and allocates
  object into persistent arena of PS.
  
  Removed sp_merge_table_hash(), sp_open_and_lock_tables(),
  sp_unlock_tables(), sp_merge_routine_tables() methods since they are not
  used by new prelocking mechanism.
  
  Added sp_add_sp_tables_to_table_list() which serves for adding tables needed
  by routines used in query to the query table list for prelocking.
sql/sp_head.h:
  class sp_head:
  - Added m_spfuns, m_spprocs members for storing names of routines used
    by this routine.
  - Added add_used_tables_to_table_list() method which allows to add
    tables needed by this routine to query's table list.
  - Converted sp_merge_table_list() to sp_head::merge_table_list() method.
  - Changed semantics of THD::m_sptabs. Now it is multi-set which contains
    only tables which are used by this routine and not routines that are
    called from this one.
  
  Removed sp_merge_routine_tables(), sp_merge_table_hash(),
  sp_open_and_lock_tables(), sp_unlock_tables() calls since they are not
  used for our prelocking list calculation.
  
  Added auxilary sp_lex_keeper class to which instructions delegate
  responsibility for handling LEX and preparations before executing
  statement or calculating complex expression. This class uses
  new sp_instr::exec_core() method which is responsible for executing
  instruction's core function after all preparations were made.
  
  All instructions which hold and calculate complex expression now have
  their own LEX (by aggregating sp_lex_keeper instance). sp_instr_stmt
  now uses sp_lex_keeper too.
  
  Removed sp_instr_set_user_var class which is no longer used, because
  nowdays we allow execution of statements in stored functions and
  triggers.
sql/sp_rcontext.cc:
  Now sp_cursor holds pointer to sp_lex_keeper instead of LEX.
sql/sp_rcontext.h:
  Now sp_cursor holds pointer to sp_lex_keeper instead of LEX.
sql/sql_acl.cc:
  acl_init(), grant_init():
    Now we use simple_open_n_lock_tables() instead of explicit
    calls to open_tables() and mysql_lock_tables().
sql/sql_base.cc:
  Implemented support for execution of statements in "prelocked" mode.
  
  When we have statement which uses stored routines explicitly or
  implicitly (via views or triggers) we have to open and lock all tables
  for these routines at the same time as tables for the main statement.
  In fact we have to do implicit LOCK TABLES at the begining of such
  statement and implict UNLOCK TABLES at its end. We call such mode
  "prelocked".
  
  When open_tables() is called for the statement tables which are needed
  for execution of routines used by it are added to its tables list
  (this process also caches all routines used). Implicit use of routines
  is discovered when we open view or table with trigger and apropriate
  tables are added to the table list at this moment. Statement which has
  such extra tables in its list (well actually any that uses functions)
  is marked as requiring prelocked mode for its execution.
  
  When lock_tables() sees such statement it will issue implicit LOCK TABLES
  for this extended table list instead of doing usual locking, it will also
  set THD::prelocked_mode to indicate that we are in prelocked mode.
  
  When open_tables()/lock_tables() are called for statement of stored
  routine (substatement), they notice that we are running in prelocked mode
  and use one of prelocked tables from those that are not used by upper
  levels of execution.
  
  close_thread_tables() for substatement won't really close tables used
  but will mark them as free for reuse instead.
  
  Finally when close_thread_tables() is called for the main statement it
  really unlocks and closes all tables used.
  
  Everything will work even if one uses such statement under real LOCK
  TABLES (we are simply not doing implicit LOCK/UNLOCK in this case).
sql/sql_class.cc:
  Added initialization of THD::prelocked_mode member.
sql/sql_class.h:
  - Added prelocked_mode_type enum and THD::prelocked_mode member
    which are used for indication whenever "prelocked mode" is on 
    (i.e. that statement uses stored routines and is executed under
     implicit LOCK TABLES).
  - Removed THD::shortcut_make_view which is no longer needed.
    We use TABLE_LIST::prelocking_placeholder for the same purprose
    now.
sql/sql_handler.cc:
  Changed open_tables() invocation.
  Now its 2nd parameter is in/out since it can add elements to table list.
sql/sql_lex.cc:
  lex_start():
    Added initialization of LEX::query_tables_own_last.
    Unused LEX::sptabs member was removed.
  st_lex::unlink_first_table()/link_first_table_back():
    We should update LEX::query_tables_last properly if table list
    contains(ed) only one element.
sql/sql_lex.h:
  LEX:
  - Removed sptabs member since it is no longer used.
  - Added query_tables_own_last member, which if non-0 indicates that
    statement requires prelocking (implicit LOCK TABLES) for its execution
    and points to last own element in query table list. If it is zero
    then this query does not need prelocking.
  - Added requires_prelocking(), mark_as_requiring_prelocking(),
    first_not_own_table() inline methods to incapsulate and simplify
    usage of this new member.
sql/sql_parse.cc:
  dispatch_command():
    To properly leave prelocked mode when needed we should call
    close_thread_tables() even if there are no open tables.
  mysql_execute_command():
  - Removed part of function which were responsible for doing implicit
    LOCK TABLES before statement execution if statement used stored 
    routines (and doing UNLOCK TABLES at the end).
    Now we do all this in open_tables()/lock_tables()/close_thread_tables()
    instead.
  - It is also sensible to reset errors before execution of statement
    which uses routines.
  - SQLCOM_DO, SQLCOM_SET_OPTION, SQLCOM_CALL
    We should always try to open tables because even if statement has empty
    table list, it can call routines using tables, which should be preopened
    before statement execution.
  - SQLCOM_CALL
    We should not look up routine called in mysql.proc, since it should be
    already cached by this moment by open_tables() call.
  - SQLCOM_LOCK_TABLES
    it is better to use simple_open_n_lock_tables() since we want to avoid
    materialization of derived tables for this command.
sql/sql_prepare.cc:
  mysql_test_update():
    Changed open_tables() invocations. Now its 2nd parameter is in/out
    since it can add elements to table list.
  check_prepared_statement():
    Since now we cache all routines used by statement in open_tables() we 
    don't need to do it explicitly.
  mysql_stmt_prepare():
    Now we should call close_thread_tables() when THD::lex points to the
    LEX of statement which opened tables.
  reset_stmt_for_execute():
    Commented why we are resetting all tables in table list.
sql/sql_trigger.h:
  Table_triggers_list::process_triggers():
    We should surpress sending of ok packet when we are calling trigger's
    routine, since now we allow statements in them.
sql/sql_update.cc:
  Changed open_tables() invocations.
  Now its 2nd parameter is in/out since it can add elements to table list.
sql/sql_view.cc:
  mysql_make_view():
  - Removed handling of routines used in view. Instead we add tables which
    are needed for their execution to statement's table list in 
    open_tables().
  - Now we use TABLE_LIST::prelocking_placeholder instead of 
    THD::shortcut_make_view for indicating that view is opened
    only to discover which tables and routines it uses (this happens
    when we build extended table list for prelocking). Also now we try
    to avoid to modify main LEX in this case (except of its table list).
  - Corrected small error we added tables to the table list of the main
    LEX without updating its query_tables_last member properly.
sql/sql_yacc.yy:
  Now each expression which is used in SP statements and can contain
  subquery has its own LEX. This LEX is stored in corresponding sp_instr
  object and used along with Item tree for expression calculation.
  
  We don't need sp_instr_set_user_var() anymore since now we allow
  execution of statements in stored functions and triggers.
sql/table.h:
  Added TABLE_LIST::prelocking_placeholder member for distinguishing
  elements of table list which does not belong to the statement itself
  and added there only for prelocking (as they are to be used by routines
  called by this statement).
sql/tztime.cc:
  my_tz_init():
    Now we use more simplier simple_open_n_lock_tables() call instead of 
    open_tables()/lock_tables() pair.
