This file is necessary for Windows builds.

There are 2 different share directories, one if builddir/share (with compiled errmsg.sys) 
and another one is $sourcedir/share and contains some /charsets/*.xml files.
second one should be refered to  as MYSQL_CHARSETSDIR and  MYSQL_SHAREDIR  $builddir/share

Compilation failure problems on non-i386 platforms.
Adding missing parenthesis.

If a prepared statement used both a MyISAMMRG table and a stored 
function or trigger, execution could fail with "No such table"
error or crash. 
The error would come from a failure of the MyISAMMRG engine
to meet the expectations of the prelocking algorithm, 
in particular maintain lex->query_tables_own_last pointer
in sync with lex->query_tables_last pointer/the contents
of lex->query_tables. When adding merge children, the merge
engine would extend the table list. Then, when adding 
prelocked tables, the prelocking algorithm would use a pointer
to the last merge child to assign to lex->query_tables_own_last.
Then, when merge children were removed at the end of
open_tables(), lex->query_tables_own_last
was not updated, and kept pointing
to a removed merge child.

The fix ensures that query_tables_own_last is always in
sync with lex->query_tables_last.

This is a regression introduced by WL#4144 and present only
in next-4284 tree and 6.0.

MDL_lock::find_deadlock".

On some platforms deadlock detector in metadata locking 
subsystem under certain conditions might have exhausted
stack space causing server crashes.

Particularly this caused failures of rqg_mdl_stability
test on Solaris in PushBuild.

During search for deadlock MDL deadlock detector could 
sometimes encounter loop in the waiters graph in which 
MDL_context which has started search for a deadlock 
does not participate. In such case our algorithm will 
continue looping assuming that either this deadlock will 
be resolved by MDL_context which has created it (i.e.
by one of loop participants) or maximum search depth
will be reached. 
Since max search depth was set to 1000 in the latter case 
on platforms where each iteration of deadlock search 
algorithm needs more than DEFAULT_STACK_SIZE/1000 bytes 
of stack (around 192 bytes for 32-bit and around 256 bytes 
for 64-bit platforms) we might have exhausted stack space.

This patch solves this problem by reducing maximum search
depth for MDL deadlock detector to 32. This should be safe
at the moment as it is unlikely that each iteration of the 
current deadlock detector algorithm will consume more than 
1K of stack (thus total amount of stack required can't be
more than 32K) and we require at least 80K of stack in order
to open any table. Also this value should be (hopefully) big
enough to not cause too much false deadlock errors (there
is an anecdotal evidence that real-life deadlocks are
typically shorter than that).

Additional reasearch should be conducted in future in order
to determine the more optimal value of maximum search depth.

This patch does not include test case as existing
rqg_mdl_stability test can serve as one.

This patch removes the unused server variable
"table_lock_wait_timeout".

TEMPORARY + HANDLER + LOCK + SP".

Server crashed when one: 
1) Opened HANDLER or acquired global read lock
2) Then locked one or several temporary tables with
   LOCK TABLES statement (but no base tables).
3) Then issued any statement causing commit (explicit 
   or implicit).
4) Issued statement which should have closed HANDLER
   or released global read lock.
   
The problem was that when entering LOCK TABLES mode in the
scenario described above we incorrectly set transactional
MDL sentinel to zero. As result during commit all metadata 
locks were released (including lock for open HANDLER or
global metadata shared lock). Indeed, attempt to release
metadata lock for the second time which happened during
HANLDER CLOSE or during release of GLR caused crash.

This patch fixes problem by changing MDL_context's
set_trans_sentinel() method to set sentinel to correct 
value (it should point to the most recent ticket).

DDL workload".

When a RENAME TABLE or LOCK TABLE ... WRITE statement which
mentioned the same table several times were aborted during 
the process of acquring metadata locks (due to deadlock 
which was discovered or because of KILL statement) server 
might have crashed.

When attempt to acquire all locks requested had failed we
went through the list of requests and released locks which
we have managed to acquire by that moment one by one. Since 
in the scenario described above list of requests contained 
duplicates this led to releasing the same ticket twice and 
a crash as result.

This patch solves the problem by employing different approach
to releasing locks in case of failure to acquire all locks
requested. 
Now we take a MDL savepoint before starting acquiring locks 
and simply rollback to it if things go bad.
