branches/zip: Merge revisions 6350:6424 from branches/5.1:

  ------------------------------------------------------------------------
  r6421 | jyang | 2010-01-12 07:59:16 +0200 (Tue, 12 Jan 2010) | 8 lines
  Changed paths:
     M /branches/5.1/row/row0mysql.c

  branches/5.1: Fix bug #49238: Creating/Dropping a temporary table
  while at 1023 transactions will cause assert. Handle possible
  DB_TOO_MANY_CONCURRENT_TRXS when deleting metadata in
  row_drop_table_for_mysql().

  rb://220, approved by Marko

  r6422 | marko | 2010-01-12 11:34:27 +0200 (Tue, 12 Jan 2010) | 3 lines
  Changed paths:
     M /branches/5.1/handler/ha_innodb.cc
     M /branches/5.1/handler/ha_innodb.h

  branches/5.1: Non-functional change:
  Make innobase_get_int_col_max_value() a static function.
  It does not access any fields of class ha_innobase.
  ------------------------------------------------------------------------
  r6424 | marko | 2010-01-12 12:22:19 +0200 (Tue, 12 Jan 2010) | 16 lines
  Changed paths:
     M /branches/5.1/handler/ha_innodb.cc
     M /branches/5.1/handler/ha_innodb.h

  branches/5.1: In innobase_initialize_autoinc(), do not attempt to read
  the maximum auto-increment value from the table if
  innodb_force_recovery is set to at least 4, so that writes are
  disabled. (Bug #46193)

  innobase_get_int_col_max_value(): Move the function definition before
  ha_innobase::innobase_initialize_autoinc(), because that function now
  calls this function.

  ha_innobase::innobase_initialize_autoinc(): Change the return type to
  void.  Do not attempt to read the maximum auto-increment value from
  the table if innodb_force_recovery is set to at least 4.  Issue
  ER_AUTOINC_READ_FAILED to the client when the auto-increment value
  cannot be read.

Fix Bug #46193 crash when accessing tables after enabling
innodb_force_recovery option

Fix Bug#49238 Creating/Dropping a temporary table while at 1023

* srv/srv0start.c: Display the zlib version number at startup.
* srv/srv0start.c:
Display the zlib version number at startup.
InnoDB compressed tables use zlib, and the implementation depends
on the zlib function compressBound(), whose definition was slightly
changed in zlib version 1.2.3.1 in 2006. MySQL bundles zlib 1.2.3
