Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC
flag, while anything else is compiled with SAFEMALLOC.

As a consequence, my_hash_init used inside federatedx initialization does not
provide correct caller info parameters (file, line) , so they are initialized with 
whatever is on stack. When info about allocated memory is output in
COM_DEBUG command, the server crashes trying to output string starting at
0xcccccccccccccccc.

The fix is to remove SAFEMALLOC  preprocessor flags 
from every CMakeLists.txt, except the top-level one.

Also, SAFEMALLOC is not defined by default now, instead
there is WITH_DEBUG_FULL CMake option which adds 
-DSAFEMALLOC to C and C++ flags in debug compilation. 
This option is off by  default, because 
1) Debug C runtime already has heap debugging builtin with 
 overwrite and leak detection
2)safemalloc considerably slows down the tests.


Note also  that 
- SAFEMALLOC is gone  in MySQL5.5
- On Windows, heap related overflows can also be found using free pageheap utility
(that is also part of application verifier). This is even more efficient if there are no other layers 
on top of Windows heap allocator, e.g  it is most efficient with release version.

 
MTR_VS_CONFIG is now determined by looking at parent directory 
of sql\*\mysqld.exe,  instead of looking at *\*\BuildLog.htm

Reason : VS2010 does not create BuildLog.htm, hence prior method did not work.

  -  Remove all mentioning of /MAP /MAPINFO link options (does not work in VS2010).
     Remove map files from packaging.
  -  Fix warning about ETIMEDOUT being redefined.
  -  Fix  warning about FSP_EXTENT_SIZE in xtradb  (32/64 bit right shift mismatch)
  -  Silence warnings coming from  generated  code (flex/bison) in xtradb/innodb_plugin.
  -  Be nice to people without cygwin (me) and add win/configure-mariadb.bat with options suitable for quick compilation, e.g no embedded

Switch makefiles to use libtool to build libmysqld.so, as well as all its
dependencies.

The previous MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() declaration is removed,
as it does not work well with a libtool build. Instead, plugins that need it
can specify an alternate object in MYSQL_PLUGIN_STATIC() that will be used for
embedded library. The plugin must then take care itself of compiling the
special object for embedded, rebuilding the source files previously listed in
MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() with @plugin_embedded_defs@ in
CFLAGS/CXXFLAGS. The extra target @XXX_embedded_static_target@ is available
for the special object, this will be empty when --without-embedded-server.

All in-tree plugins are changed to build their static targets with libtool.
Additional plugins that want to work with libmysqld.so will need to be
similarly modified to build with libtool (or otherwise provide an -fPIC
object). Dynamically loaded plugins are not affected.

The old libraries like libmysys.a, libmyisam.a and similar libraries, which
were installed by `make install` though this is of little use, are still built
and installed to not break package scripts etc. that expect them. These
libraries are kept static to avoid introducing new .so dependencies.

The patch also fixes a handfull of duplicate symbol linker errors, where we
included some object twice during linking; these for one reason or another did
not produce errors before but caused problems on some platforms with this
patch (eg. Mac OS X linker is more strict for shared objects).

This patch only does what is necessary to build libmysqld.so. There are some
more cleanups that are possible now that we are using libtool more fully,
which could done in subsequent patches (though we may not bother as we are
switching from autotools to CMake anyway):

 - In libmysql_r/, we should be able to just link libmysys.la etc, instead of
   symlinking and re-compiling sources into the directory.

 - In libmysql/, we can similarly avoid symlinking and recompiling sources if
   we instead build a libmysys_nothread.la library with appropriate CFLAGS and
   link that.

 - In sql/, we can build a separate target libmysql_int.la with appropriate
   CFLAGS for embedded and use that in libmysqld/ instead of symlinking
   sources.

 - libmysys.a, libmyisam.a and similar libraries could be installed as .so
   also to save on code size; or alternatively could be not installed at all.

This patch removes most remaining delays due to uninteruptible sleep()
during shutdown, as found using PMP. This makes standard test run very
close in speed to with --loose-innodb-fast-shutdown=2, and greatly
speeds up running the test suite.

sql/mysqld.cc:
  Poll for threads to die every 20 msec during shutdown, rather than force
  a wait for 2 full seconds should one thread be a little slow to exit
  (this was seen occasionally in mysql-test-run).
storage/xtradb/include/srv0srv.h:
  Rename the event, as we now use it to wakeup more threads during shutdown.
storage/xtradb/log/log0log.c:
  Rename the event, as we now use it to wakeup more threads during shutdown.
storage/xtradb/srv/srv0srv.c:
  Replace some hardcoded sleep()s with os_wait_event_time() that can be
  interrupted early during server shutdown to avoid unnecessary delays.

  Fixed bug in pagecache_delete_internal() when deleting block that was flushed by another thread (fixed bug when block->next_used was unexpectedly null)
  Cleanup: moved pagecache_pthread_mutex_unlock() over comments and asserts to be just before pagecache_fwrite()

This fixes a bug that gave ER_FILE_TOO_SHORT error when scanning Aria tables.

storage/maria/ma_blockrec.c:
  Changed code so that we update share->state.state.data_file_length after page cache write is done.
  When scanning pages, stop when you are at 'data_file_length'.
  (We can't trust the bitmap as there may be reserved pages in the bitmap that are not yet written).

Implement os_event_wait_time() for POSIX systems.

In the purge thread, use os_event_wait_time() when sleeping rather than sleep,
and signal the event when server shuts down, so we do not need to wait for
upto 10 seconds until the purge thread wakes up.

Also fix bug that warnings that were pushed after we call set_ok_status() were
not included in the waning count sent to the client in the result packet.

Also in mysqltest, in recursive die() invocation at least print the message
before aborting.

client/mysqltest.cc:
  If we detect recursive die(), at least print the message before aborting.
mysql-test/r/warnings_debug.result:
  Test case.
