            my_global.h first

We may end up with a compilation failure on certain platforms
because zlib.h is included before my_global.h.

Fixed by moving zlib.h inclusion down after my_global.h.

            e.g.MYSQL_AUDIT_GENERAL_ERROR

General audit API (MYSQL_AUDIT_GENERAL_CLASS) didn't expose event
subclass to plugins.

This patch exposes event subclass to plugins via
struct mysql_event_general::event_subclass.

This change is not compatible with existing general audit plugins.
Audit interface major version has been incremented.

The problem was that the code that works with stored routines was present
in mysql_system_tables.sql. This is wrong because until upgrade is finished,
stored routines may be (and were) not available.

The fix is to move that code to the end of mysql_system_tables_fix.sql.

Allow stored procedure variables in LIMIT clause.
Only allow variables of INTEGER types. 
Handle negative values by means of an implicit cast to UNSIGNED 
(similarly to prepared statement placeholders).
Add tests.
Make sure replication works by not doing NAME_CONST substitution
for variables in LIMIT clause.
Add replication tests.

Bug#13174: SHA2 function
Patch contributed from Bill Karwin, paper unnumbered CLA in Seattle

Implement SHA2 functions.

Chad added code to make it work with YaSSL.  Also, he removed the 
(probable) bug of embedded server never using SSL-dependent 
functions.  (libmysqld/Makefile.am didn't read ANY autoconf defs.)

Function specification:
  SHA2( string cleartext, integer hash_length ) 
    -> string hash, or NULL
where hash_length is one of 224, 256, 384, or 512.  If either is 
NULL or a length is unsupported, then the result is NULL.  The 
resulting string is always the length of the hash_length parameter
or is NULL.

Include the canonical hash examples from the NIST in the test
results.

Polish and address concerns of reviewers.

pthread_t is not defined unless my_pthread.h is included.

Problem: Segmentation fault in add_group_and_distinct_keys() when accessing
field of what is assumed to be an Item_field object.

Cause: In case of views, the item added to list by is_indexed_agg_distinct() 
was not of type Item_field, but Item_ref.

Resolution:  Add the real Item_field object, the one referred to by 
Item_ref object, to the list, instead.

when trying to build innodb as plugin.

The reason for the error is mismatch in mysql_temp_dir_list
declaration between mysqld.h and usage in ha_innodb.cc

Add missing MYSQL_PLUGIN_IMPORT to mysql_tmpdir_list
(variables exported by the server and used by plugin need it).

Fix tons of warnings about mismatch struct and class usage.

Tree cleaup after the last major merges in mysql-trunk:

The files sql/lex_hash.h and sql/sql_yacc.h are automatically
generated, and should not be checked in the configuration management system.
These files are now removed.
No changes are required for .bzrignore, which already listed these files
(and similar files in libmysqld/).

The file storage/perfschema/unittest/pfs_timer-t.cc did not build
after the header files refactoring affecting mysql_priv.h
The file now builds properly using sql_priv.h

Adding my_global.h first in all files using
NO_EMBEDDED_ACCESS_CHECKS.

Correcting a merge problem resulting from a changed definition
of check_some_access compared to the original patches.

The failing assertion was written with the assumption that a NULL
string can never be passed to my_strtod(). However, an empty string
may be passed under some circumstances by passing str == NULL and
*end == NULL.

Fixed the assertion to take the above case into account.

Adding include to build on Windows.

Adding includes of my_global.h that seems to be necessary on Windows.

Moving an extern "C" to not cover #includes.

- Adding include/mysql/innodb_priv.h which was missing before.
- Updated .bzrignore to ignore CMake generated cruft.

Minor fixes required because of changes since patches were developed.

Fixing merge problem that causes CSV engine to misbehave.

Post-merge fix.
