mysql.procs_priv table itself does not get replicated.
Inserting routine privilege record into mysql.procs_priv table
is triggered by creating function/procedure statements
according to current user's privileges.
Because the current user of SQL thread has GLOBAL_ACL,
which doesn't need any check mysql.procs_priv privilege
when create/alter/execute routines.
Corresponding GLOBAL_ACL privilege user
doesn't insert routine privilege record into
mysql.procs_priv when creating a routine.

Fixed by switching the current user of SQL thread to definer user if
the definer user exists on slave.
That populates procs_priv, otherwise to keep the SQL thread
user and procs_priv remains unchanged.

Any statement reading corrupt archive data file
(CHECK/REPAIR/SELECT/UPDATE/DELETE) may cause assertion
failure in debug builds. This assertion has been removed
and an error is returned instead.

Also fixed that CHECK/REPAIR returns vague error message
when it mets corruption in archive data file. This is
fixed by returning proper error code.

- merged the fix to 5.1
- extended to cover I_S.PROCESSLIST.TIME
- Changed the column type of I_S.PROCESSLIST.TIME from LOGNLONG
  UNSIGNED
  to LONG (to match the SHOW PROCESSLIST type)
- Added a test case

"Release_lock("hello")" is now also successful when delivering NULL, replaced two sleeps by wait_condition. The last two "sleep 1" have not been replaced as all tried wait conditions leaded to nondeterministic results, especially to succeeding concurrent updates. To replace the sleeps there should be some time planned (or internal knowledge of the server may help).
 

sql/sql_select.cc:
  the if() separate arguments checks are slightly faster.

Re-recording of .result files for additional tests that use this include file.

If a sys-var has a base and a block-size>1, and then a
user-supplied value >= minimum ended up below minimum
thanks to block-size alignment, we threw a warning.
This meant for instance that when getting, then setting
the minimum, we'd see a warning. This was needlessly
confusing. (updated patch)

Replaced a call to load_defaults() in sql_plugin.cc with 
its thread-safe version.

select where .. (col=col and col=col) or ... (false expression)

Problem: optimizer didn't take into account a singular case 
when we eliminated all the predicates at the AND level of WHERE.
That may lead to wrong results.

Fix: replace (a=a AND a=a...) with TRUE if we eliminated all the
predicates.

    - replacing equality predicates by multiple equality items check

  replace them with TRUE if so.

Revised patch incorporating cleaner test code brought up during review.
Removed the use of grep and accomplished same actions via SQL / use of the server.

Runs as before on *nix systems and now runs on Windows without Cygwin as well.

THD::start_time has a dual meaning : it's either the time since the process
entered a given state or is the transaction time returned by e.g. NOW().
This causes problems, as sometimes THD::start_time may be set to a value
that is correct and needed when used as a base for NOW(), but these times
may be arbitrary (SET @@timestamp) or non-local (coming from the master 
through the replication feed).
If one such non-local time is set there's no way to return a correct value
for e.g. SHOW PROCESSLIST or SELECT ... FROM INFORMATION_SCHEMA.PROCESSLIST.
Fixed by making the Time column in SHOW PROCESSLIST SIGNED LONG instead of 
UNSIGNED LONG and doing the correct conversions.
      
Note that no reliable test suite can be constructed, since it would require
knowing the local time and can't be achieved by the means of the current test
suite.

  Bug #22047: make the Time in SHOW PROCESSLIST LONG from 
  LONG UNSIGNED

      
There are some recursive targets that automake generates which reference
DIST_SUBDIRS.  It's critical, then, for such subdirs to exist even if they
won't be built as part of SUBDIRS.

During a VPATH build, it is the configure script which creates the subdirs
(when it processes the AC_CONFIG_FILES() for each subdir's Makefile).  If
autoconf doesn't create a subdir's Makefile, then the recursive make will fail
when it is unable to cd into that subdir.

This isn't a problem in non-VPATH builds, because the subdirs are all present
in the source tarball.  So the problem only shows up during 'make distcheck',
which does a VPATH build.

The fix is to look, when configure is being created by autoconf, for any
plugin subdirectories.  These are the dynamic subdirectories which need to be
handled specially.  It's enough to tell autoconf to generate a Makefile for
any Makefile.am found in the plugin directory - all plugin subdirectories
using automake (i.e., listed in the plugin's DIST_SUBDIRS) will have a
Makefile.am.

This is done by calling 'find'.  This means that 'find' must be in the PATH on
the host that is running autoconf.  'find' is NOT needed when calling
configure, so it is not an additional dependency for the user.

Finally, ha_ndbcluster.m4 had called AC_CONFIG_FILES() on all those subdir
Makefiles, but only when the plugin was actually being built.  So it didn't
work in the case that NDB was not being built.  All of those Makefiles have to
be removed from this static list, since the plugin machinery is now adding
them automatically.  autoconf fails if a file is duplicated in
AC_CONFIG_FILES().
