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.

                   ~40Mb after mysqldump/import 
        
When the input string exceeds the maximum allowed size for the 
internal buffer, batch_readline() returns a truncated string. 
Since there was no way for a caller to determine whether the 
string was truncated or not, the command line client assumed 
batch_readline() to always return the whole input string and 
appended a newline character. This resulted in garbled data 
when importing dumps containing strings longer than the 
maximum input buffer size. 
  
Fixed by adding a flag to the batch_readline() interface to 
signal a truncated string to the caller. 
  
Other minor problems fixed during patch implementation: 
 
- The maximum allowed buffer size for batch_readline() was set 
up depending on the client's max_allowed_packet value. It does 
not actully make any sense, as those variables are not 
related. The input buffer size limit is now always set to 1 
MB. 
  
- fill_buffer() did not always set the EOF flag. 
 
- The input buffer could actually grow twice as the specified 
limit due to insufficient checks in intern_read_line(). 

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.

The reason for the error is incorrectly specified link dependencies
for mysql_embedded, mysqltest_embedded and mysql_client_test_embedded
in CMakeLists.txt (ADD_DEPENDENCIES should be TARGET_LINK_LIBRARIES)

become negative

- 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).
 

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.

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.
