Bug#37536: Thread scheduling causes performance degradation at low thread count

Deprecated --skip-thread-priority startup option as newer versions of
the server won't change the thread priorities by default.

Giving threads different priorities might yield marginal improvements
in some platforms (where it actually works) but on the other hand it
might cause significant degradation depending on the thread count and
number of processors. Meddling with the thread priorities is a not a
safe bet as it is very dependent on the behavior of the cpu scheduler
and system where MySQL is being run.

From MySQL 6.0 and up the default behavior is that of not modifying
the threads priorities.

sql/mysqld.cc:
  Deprecate --skip-thread-priority

  pre push fix for bug#38804
  Found a missing 'if' for releasing the mutex

from stored procedure. 

Problem: we replace all references to local variables in stored procedures     
with NAME_CONST(name, value) logging to the binary log. However, if the
value's collation differs we might get an 'illegal mix of collation'           
error as we don't pass the collation to the function.

Fix: pass the value's collation to NAME_CONST().

Note: actually we should pass to NAME_CONST() the value's derivation as well.
It's impossible without the parser modifying. Now we always set the 
derivation to DERIVATION_IMPLICIT, the same as local variables have.

Post-merge bug fix: lock_type is a enumeration type and not a bit mask.

sql/sql_cache.cc:
  Check for lock type explicitly. Also err on the safe side and
  invalidate the query cache for any write lock.

Server created "arc" directories inside database directories and
maintained there useless copies of .frm files.

Creation and renaming procedures of those copies as well as
creation of "arc" directories has been discontinued.
Removal procedure has been kept untouched to be able to
cleanup existent database directories by the DROP DATABASE
query. Also view renaming procedure has been updated to remove
these directories.


sql/parse_file.cc:
  Fixed bug #17823: 'arc' directories inside database directories.
  View/table creation and renaming procedures maintained
  backup copies of .frm files. Those copies are unused yet,
  so this feature was incomplete and unnecessary.
  
  1. Unwanted code has been hidden by FRM_ARCHIVE ifdefs
  (the FRM_ARCHIVE macro is not defined).
  
  2. Renaming procedure has been modified to remove obsolete
  "arc" directories.
sql/parse_file.h:
  Fixed bug #17823: 'arc' directories inside database directories.
  The "thd" parameter has been added to the rename_in_schema_file()
  function.
sql/sql_db.cc:
  Fixed bug #17823: 'arc' directories inside database directories.
  Scope of the mysql_rm_arc_files() function has been changed to
  global for use from the parse_file.cc file.
sql/sql_view.cc:
  Fixed bug #17823: 'arc' directories inside database directories.
  Added the "thd" argument to rename_in_schema_file() calls.

     JOIN for the subselect wasn't cleaned if we came upon an error
     during sub_select() execution. That leads to the assertion failure

    lex->unit.cleanup() call added if not substatement

The problem is that when statement-based replication was enabled,
statements such as INSERT INTO .. SELECT FROM .. and CREATE TABLE
.. SELECT FROM need to grab a read lock on the source table that
does not permit concurrent inserts, which would in turn be denied
if the source table is a log table because log tables can't be
locked exclusively.

The solution is to not take such a lock when the source table is
a log table as it is unsafe to replicate log tables under statement
based replication. Furthermore, the read lock that does not permits
concurrent inserts is now only taken if statement-based replication
is enabled and if the source table is not a log table.

include/thr_lock.h:
  Introduce yet another lock type that my get upgraded depending
  on the binary log format. This is not a optimal solution but
  can be easily improved later.

sql/mysql_priv.h:
  Export new function.
sql/mysqld.cc:
  Remove using_update_log.
sql/sql_base.cc:
  Introduce function that returns the appropriate read lock type
  depending on how the statement is going to be replicated. It will
  only take a TL_READ_NO_INSERT log if the binary is enabled and the
  binary log format is statement-based and the table is not a log table.
sql/sql_parse.cc:
  Remove using_update_log.
sql/sql_update.cc:
  Use new function to choose read lock type.
sql/sql_yacc.yy:
  The lock type is now decided at open_tables time. This old behavior was
  actually misleading as the binary log format can be dynamically switched
  and this would not change for statements that have already been parsed
  when the binary log format is changed (ie: prepared statements).

      
In order to improve the performance when replicating to partitioned
myisam tables with row-based format, the number of rows of current 
rows log event is estimated and used to setup storage engine for bulk
inserts.

Bug#38311 - Fix of some cruft from remove_files in ndb_autodiscover.test, clean up of distinct.test,

A stored procedure involving substrings could crash the server on certain
platforms because of invalid memory reads.
          
During storing the new blob-field value, the cached value's address range
overlapped that of the new field value. This caused problems when the 
cached value storage was reallocated to provide access for a new 
characater set representation. The patch checks the address ranges, and if
they overlap, the new field value is copied to a new storage before it is
converted to the new character set.


mysql-test/r/sp.result:
  Added result set
mysql-test/t/sp.test:
  Added test case
sql/field.cc:
  The source and destination address ranges of a character conversion must not overlap or the 'from' address will be invalidated as the temporary value-
  object is re-allocated to fit the new character set.
