Merged and fixed Oleg's changes in slow_extended.patch and
response_time_distribution.patch:

* Removed 'percona' suite, as that migration should be done for all
tests when decided
* replaced SET SESSION debug = "+d,query_exec_time" and /* query_exec_time=...*/ comments
with a debug-only system variable (which is also replicated to make
replication tests possible)
* replaced ugly macros in slow_extended patch with inline functions
* changed all slow_extended and response_time_distribution tests to use the system variable
* fixed percona_query_response_time-replication.test to actually test what it is supposed to test,
i.e. queries coming from SBR rather than running them on the slave
(which is no different from the "normal" QRT test)
* fixed broken percona_query_response_time-stored.test:
** wasn't really testing stored routines due to a wrong include
** specifying stored proc argument in a /* query_exec_time=...*/ comment didn't really work
** TIME is a reserved word, so using it as a variable name is not a good idea
** stored proc was trying to INSERT into a non-existing table
* moved error_pad.patch before response_time_distribution.patch in series as the latter
depends on the first one (as in does not build)

Bug #745241: quering global_temporary_tables causes server crash

The problem was in an insufficient locking in
fill_global_temporary_tables(). Iterating thread's temporary_tables list
could lead to race conditions, because other server code assumes that
list to only be accessed by a single (the current) thread at any time.

Fixed by introducing a new mutex in THD protecting the temporary_tables
list and acquiring that mutex when modifying the list or in
fill_global_temporary_tables().
