Fixed problem that global status variables 'bytes_recieved' and 'binlog_bytes_written' where not correctly updated 

Fixed lock sorting and lock check issues with thr_lock that caused warnings when running test suite.
Safety check that could cause core dump when doing create table with virtual column.

mysql-test/mysql-test-run.pl:
  Show also warnings from thr_lock (which starts with just Warning, not Warning:)
mysql-test/r/lock.result:
  Added test that showed not relevant warning when using table locks.
mysql-test/t/lock.test:
  Added test that showed not relevant warning when using table locks.
mysys/thr_lock.c:
  Fixed sorting of locks.
  (Old sort code didn't handle case where TL_WRITE_CONCURRENT_INSERT must be sorted before TL_WRITE)
  Added more information to check_locks warning output.
  Fixed wrong testing of multiple different write locks for same table.
sql/item_cmpfunc.cc:
  Safety check that could cause core dump when doing create table with virtual column.

CMake 2.8.4 crashed on this line
 IF(something AND IS_DIRECTORY(something_else))
when both  "something" and "something_else" were empty.

Changing the line slightly (using cascading "IF" instead)  solved the crash.

Disable call to setpriority() in pbxt. This caused mysqld to run with nice priority -19, which was far from optimal.

mysql-test/suite/innodb/r/innodb_bug60049.result:
  Updated results
mysql-test/suite/innodb/t/innodb_bug60049.test:
  Force global.innodb_fast_shutdown to 0 as test require it
mysql-test/suite/innodb_plugin/t/innodb_bug60049.test:
  Force global.innodb_fast_shutdown to 0 as test require it
storage/pbxt/src/pthread_xt.cc:
  Disable call to setpriority()

The error message is now based on GetLastError() rather than errno. 

Background: errno is C runtime specific and in many circumstances 
it is not set, e.g when using Win32 API or socket functions.

This simplifies postmortem analysis for crashes reported via Winqual.

HEAP is deprecated in favor of MEMORY.

Ensure we don't read a MariaDB 5.3 errmsg.sys file or new errmsg.sys file with holes for not used error messages

sql/derror.cc:
  Ensure we don't read a MariaDB 5.3 errmsg.sys file with moved error messages or a new errmsg.sys file with holes for not used error messages
  If error message file didn't exist and we have not read one in the past, don't continue.
  Give better error message if the errmsg.sys header has changed.

- Fix CRLF end of lines, use LF instead

The printing of include stack in the error case in mysqltest omitted the
bottom of the stack (the line number in original test case file), and instead
printed the top of the stack twice. Fix to print each element on the stack
once and only once.

- add version info for the client library, dynamic plugins and some utilities
- do not recompile client library sources 3 times (for mysqlclient , mysqlclient_notls and libmysql)
  One time is sufficient, so get rid of mysqlclient_notls, and link  static client library  to  the shared.
- remove incremental linking flag

 my_rwlock_destroy=>rwlock_destroy

- Fix  active lock in freed memory in ha_archive (share mutex was not released prior to free())
- Do not attempt vio_fastsend or vio_keepalive on named pipes and shared memory.

LPBUG#782223 : Memory released by Query_cache::resize() or Query_cache::free() contains active rwlocks.
The bug was found by application verifier. 
Fixed by destroying locks prior to free(),

LPBUG#782269 : critical sections are initialized twice in   xt_xn_init_db() 
LPBUG#782431: active lock in memory released by   xt_ind_exit()
LPBUG#782433 : xt_heap_release() does not release spinlock  hp->h_lock initialized in xt_heap_new().
LPBUG#782435: xt_exit_row_locks() tries to release unallocated locks

Made test-unit run in parlallel. This was achived by having all aria tests that uses temporary files to create the temporary file in an unique tempdirectory.
aria_chk now returns 1 if one got any warnings during check and 2 if one got errors.

Simplifies handling 5.1 in buildbot.

On Windows, do not attempt access() for special device names like
CON, PRN etc. access() would return 0, this does not mean that fiile
with this name exists.

mysql-test/r/create.result:
  test of renaming
mysql-test/r/upgrade.result:
  Now such behaviour prohibited to avoid problems.
mysql-test/t/create.test:
  test of renaming
mysql-test/t/upgrade.test:
  Now such behaviour prohibited to avoid problems.
sql/mysql_priv.h:
  Function to test table name presence added.
sql/sql_rename.cc:
  Rename fixed.
sql/sql_table.cc:
  Function to test table name presence added.
  Create fixed.

no unnecessary casting from void*, more type safety.
typos fixed.

Problem was setting DEBUG_SYNC twice in a row too fast in the test case; this
could cause the second setting to override the first before the code had time
to react to the first, causing the signal to get lost.

Fixed by waiting for the code to receive the first signal before overwriting
it in the test case.

(Test failed if we added my_sleep(200000) in event_queue::cond_wait() just before pthread_cond_wait();  Not likely scenario but better to get that fixed too)

Fixed race condition in event that could cause hang when stopping event scheduler with SET GLOBAL event_scheduler=OFF 

client/mysqltest.cc:
  Write command to be executed to the log BEFORE executing the command.
  This makes it easier to debug crashes as the log will contain the fatal command.
mysql-test/r/mysqltest.result:
  Updated results (we now get more things logged)
sql/event_queue.cc:
  Fixed race condition in event that could cause hang when stopping event scheduler with SET GLOBAL event_scheduler=OFF.
  The reason was that a kill signal could be sent between last check of thd->killed and before thd->enter_cond() in which case the signal
  would be missed and we would be stuck in Event_scheduler::stop() forever.
