libmysql/libmysql.c:
  fix for bug #7285: Disable start of embedded server when need to
  connect to an external server with libmysqld.
  
  Calling mysql_server_init with a negative value for argc will not
  start the embedded server.

include/errmsg.h:
  New libmysql error status code CR_NO_STMT_METADATA
libmysql/errmsg.c:
  Error message for CR_STMT_NO_METADATA.
  Adding an empty line to shorten further diffs when new error
  messages are added (as suggested by Monty).
libmysql/libmysql.c:
  Return error from mysql_stmt_bind_result() if the statement contains
  no metadata.
  A few comments fixed.
tests/client_test.c:
  Tests fixed: mysql_stmt_bind_result now returns error if there is no
  metadata.

  Fix for a bug #6996
  
  This fix enables that after all rows are read from a buffered result,
  mysql_stmt_data_seek(stmt,0) can rewind a counter to the beginning,
  so that rows can be re-fetched.
tests/client_test.c:
  Addition of a test for fix of the bug #6996 in client_test.c

In server we assume that datetime values stored in MYSQL_TIME struct
are normalized (and year is not greater than 9999), so we should 
perform range checks in all places then we convert something to
MYSQL_TIME. 


include/my_time.h:
  Added one more argument to set_zero_time() function to make it more 
  convinient.
  Added comment clarifying why MAX_DATE_STRING_REP_LENGTH value is 30.
include/mysql_time.h:
  Documented MySQL's internal assumptions for members of MYSQL_TIME
  structure.
libmysql/libmysql.c:
  It does not make sense to set MYSQL_TIME::time_type twice in case of 
  errors.
mysql-test/r/type_datetime.result:
  Added test for bug #6266 "Invalid DATETIME value not handled properly".
mysql-test/t/type_datetime.test:
  Added test for bug #6266 "Invalid DATETIME value not handled properly".
sql-common/my_time.c:
  str_to_datetime(): Added missing check for too big year values.
  set_zero_time(): added time_type argument, since MYSQL_TIMESTAMP_NONE
    is not the value that we want in most cases.
sql/field.cc:
  Field_datetime::store_time():
    clarified why we don't perform any range checks here.
sql/item.cc:
  Item_param::set_time():
   Added comment describing this method and range checking for TIME
   values.
sql/sql_prepare.cc:
  Removed comments about range checking for TIME values in prepared 
  statements, which are no longer true.
  set_zero_time() has one more argument now.

libmysql/libmysql.c:
  A fix for Bug#6096 "field.max_length is always zero for numeric columns
   (stmt_resultset_metadata)": set field->max_lenght for numeric
  columns when we set up skip_result functions. A minor drawback for this 
  approach is that field->max_length  can be not zero even if

  New test commands:
  --disable_ps_protocol

  NOTE: new code still has some things that needs to be cleaned up.
  For example run_query_stmt_handle_error() should be made more general so that same code can be used also by 'normal' queries
configure.in:

libmysql/libmysql.c:
  Cleanup of conversion part of libmysql (prepared statements protocol):
  - now we have basic support for any conversion sequence:
    when we don't implement direct conversion of given value to requested 
    buffer type (i.e. time -> double, or the other way around) we
    first convert i.e. time -> string and then call string -> double 
    conversion.
    param->offset is now handled only in one place.
  - conversion functions renamed from send_data_{string, long, double}
    to fetch_{string,long,double}_with_conversion. Don't be confused
    with strange diff for send_data_long: I had to move send_data_string
    before all other sends as it's used inside thesm. (Shall we have
    a forward declaration instead?-)
  - a little cleanup in read_binary_{date,time,datetime} - now type of
    date value is set inside these functions, so we can be sure
    that we always return fully filled MYSQL_TIME structure to the user
  - float -> string conversion is fixed to honor param->precision. 
    This is a step forward in fixing bug#4172
tests/client_test.c:
  test fix: now libmysql always sets MYSQL_TIME::time_type field.
  We need to set these fields in the test as later _in values are compared
  with canonical by plain memcmp.
