HAVE_IBGCC_ATOMIC_BUILTINS=>HAVE_IB_GCC_ATOMIC_BUILTINS.
Due to the typo, detection of atomics was broken. 
It also lead to valgrind error during shutdown 
(access to freed memory),which is likely present 
in all builds where atomics are not used.

Backport to 5.5.99

Reason: implementation of send/reap in mysqltest uses the same "embedded" connection in a thread different from current, so thread stack has to change when connection is used in different  OS thread..

Backport to 5.5.99

It appears that stack overflow checks for recusrive stored procedure
calls, that run in the normal server, did not work in embedded and were
 dummified with preprocessor magic( #ifndef EMBEDDED_SERVER ).
      
 The fix is to remove ifdefs, there is no reason not to run overflow checks
 and crash in deeply recursive calls. 
      
 Note: Start of the stack (thd->thread_stack variable) in embedded is not
necessarily exact but stil provides the best guess. Unless the caller of 
mysql_read_connect()   is already deep in the stack, thd->thread_stack 
variable should approximate stack  start address well.

WL#5154 and WL5182

Two result files in the sys_vars suite wasn't 
properly updated after the change in
deprecation text

The bug was that ./configure was  passing paramers to subscripts as $@, and to handle embedded spaces it needs
to be quoted as "$@".
This resulting into a bug when ./configure was called e.g with CFLAGS='-m64 -Xstrconst'..

Additionally, fixed cmake/configure.pl did not handle environment variables passed on the command line.
this is fixed in this push

"TYPE=storage_engine" is deprecated, and will be removed
in the Celosia release of MySQL.  Since the option is
present in the Betony release and the version number of
Celosia is still not decided, we need to bump the
deprecation version number back up to "6.0".

Fix contains of :
-  splitting CC/CXX if there are more that 2 space-delimited tokens, add the rest to CFLAGS
(in this case CC was set to "ccache gcc --pipe", and this broke recognition of gcc compiler
as CMake understands CC consisting of 2 space delimited tokens but not more)

-  add my_new.cc to mysys fle list if C++ operator new is not found. Always, not only
for gcc  (the original problem was that missing operator new when compiling with CXX=gcc)

MySQL with gcc 4.3.2
      
This is the final patch in the context of this bug.
