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.

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

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)

The task is to 
  (a) add a comment on indexes and 
  (b) increase the maximum length of column, table and the new index comments.

The patch committed on behalf of Yoshinori Matsunobu (Yoshinori.Matsunobu@Sun.COM).

Fix configure.js : set the variabes in cache, so they can overwrite cache variables in CMakeLists.txt

- mysql_install_db is in scripts dir now
- sql-bench is installed
-some extra support-files (e.g ini) are in support-files

 - Changes to the banner text
 - Use older AC_PROG_LIBTOOL (Bug#51009)

scripts/mysql_install_db.sh
 - Changes to banner text

Added --max-connections= argument to mysqltest and mtr
Small fix to first patch: forgot to check before free'ing connections array

in 'kostja@sun.com-20091210084103-l4f8u62u4evoy3dc'.

This file is necessary for Windows builds.

Some logic would group by suite always
Disable this if using --noreorder
Also fix getting array from collect_one_suite() in this case
Amended according to previous comment

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
