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.

storage/maria/unittest/ma_loghandler_examples.c:
  Call check_translog_description_table() to register number of log_record_type_descriptor[] events.

- 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#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().

Fix library build on mac (prevent handlersocket.so loading failure if it called from build directory)

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.

Store decimal 0.0 in zero bytes in dynamic strings.
mysqltest: Don't ignore error from mysql_stmt_fetch;  This could cause rows to be missing from log when running with --ps-protocol
Fixed wrong result length for CAST(... as TIME)






client/mysqltest.cc:

The problem was that connection con5, which is supposed to be the leader for
the third group, could if timing was bad end up as participant in the second
group, causing the test to fail.

Fixed by ensuring that group 2 is running before starting the transaction
for group 3.

Fix various warnings about conversion from bigger to smaller integer types in assignments
