of standard malloc.

Removed instance manager from builds

platforms and emphasize the fact that gcc is the default
compiler on all platforms.

Make it possible to say --compiler=SunStudio instead of
--compiler=forte

Fix a bug that lost an important flag for C++ builds.

for those cases when gcc, cc-5.0, icpc or icc isn't in the path.

Fixed handling of 32 and 64 bits.

Downgraded Solaris builds on Forte to use -xO2 rather than -xO3.

Made it possible to build 64-bits on Mac OS X

Fixed some bugs in setting CC, CXX, ASFLAGS, LDFLAGS

Fixed bugs relating to use of SunStudio/Forte in check-cpu

Reorganized code a bit

Removed the use of --with-fast-mutexes since they aren't really
fast, rather slow.

Added -static-libgcc when using gcc

Added optimising compilation flags on BSD

Added use of curses library on Solaris

Removed the use of MY_ATOMIC_MODE_RWLOCKS which removed use of
atomic instructions

Added support for Forte on Solaris/x86

removed from SHOW ENGINE InnoDB STATUS

parameter innodb_thread_concurrency_timer_based is used to
get this new feature (it is set by default). The new feature
is only available on platforms where atomic instructions are
available.

according to recommendation from Intel.

Change defaults, now large page support is default if supported
Introduced super-large-pages support for Solaris to use 256 MByte
page size rather than 4 MByte.

Removed dependency on pthread being an int

                  
The problem here is that embedded server starts handle_thread manager 
thread  on mysql_library_init() does not stop it on mysql_library_end().
At shutdown, my_thread_global_end() waits for thread count to become 0,
but since we did not stop the thread it will give up after 5 seconds.
             
Solution is to move shutdown for handle_manager thread from kill_server()
(mysqld specific) to clean_up() that is used by both embedded and mysqld.
            
This patch also contains some refactorings - to avoid duplicate code,
start_handle_manager() and stop_handle_manager() functions are introduced.
Unused variables are eliminated. handle_manager does not rely on global
variable abort_loop anymore to stop (abort_loop is not set for embedded).
            
Note: Specifically on Windows and when using DBUG version of libmysqld, 
the complete solution requires removing obsolete code my_thread_init() 
from my_thread_var(). This has a side effect that a DBUG statement 
after my_thread_end() can cause thread counter to be incremented, and 
embedded will hang for some seconds. Or worse, my_thread_init() will 
crash if critical sections have been deleted by the global cleanup 
routine that runs in a different thread. 

This patch also fixes and revert prior changes for Bug#38293 
"Libmysqld crash in mysql_library_init if language file missing".

Root cause of the crash observed in Bug#38293  was bug in my_thread_init() 
described above




client/mysql.cc:
  sql_protocol_typelib is not exported from libmysqld
  (does not make sense either)
  thus excluded from embedded client
dbug/dbug.c:
  revert changes for Bug#38293
include/my_dbug.h:
  revert changes for Bug#38293
libmysql/libmysql.c:
  Removed DBUG_POP call, because when called after my_end(), will access
  THR_key_mysys that is already deleted. The result of pthread_get_specific
  is not predictable in this case and hence DBUG_POP can crash.
libmysqld/examples/CMakeLists.txt:
  Revert changes for Bug#38293.
libmysqld/lib_sql.cc:
  code to start handle manager is factored out into 
  start_handle_manager() function
libmysqld/libmysqld.def:
  Revert changes for Bug #38293
  Remove excessive exports from libmysqld, export what API documents.
mysys/my_thr_init.c:
  Remove windows-DLL-specific workaround for something (old code, no documentation for
  what specifically). The problem is that even after my_thread_end() is finished, 
  DBUG statement can initiate my_thread_init(). This does not happen anywhere else and 
  should not happen on  Windows either.
sql/mysql_priv.h:
  - new functions start_handle_manager() and stop_handle_manager()
  - move manager_thread_in_use  variable to sql_manager.cc and made
  it static
  - remove manager_status, as it is unused
sql/mysqld.cc:
  Code to start/stop handle_manager thread is factored out into start_handle_manager()

Not the final fix, only a temporary fix

There was a missing initialization.

sql/set_var.h:
  Added an initialization missing during the merge of 37339.

with non-RSA-requesting client if server uses RSA key

matchSuite() may not find a match. 
It will return error in this case.
Added a error checking code that will prevent using uninitialized 
memory in the code based on the assumption 
that matchSuite() has found a match.

extra/yassl/src/yassl_imp.cpp:
  Bug #39178: Correct error checking added
