    Fix potentially-uninitialized critical section in Win32 DLL builds

If non-parser parts of libxml (e.g. xmlwriter) are used before a parser,
xmlOnceInit may have run (e.g. via the many paths to xmlGetGlobalState),
but not xmlInitThreads (which is called only by xmlInitParser)

Once globalkey != TLS_OUT_OF_INDEXES (which can happen in many ways),
DLLMAIN(DLL_THREAD_DETACH) may attempt to lock cleanup_helpers_cs
before it is valid. This may happen even if the thread whose exit
is triggering DllMain is from code which is not linked to libxml.

globalkey and cleanup_helpers_cs should be initialized together,
with cleanup_helpers_cs initialized first and deleted last.

To build on an Unixised setup:
   ./configure ; make ; make install
   if the ./configure file does not exist, run ./autogen.sh instead.
To build on Windows:
   see instructions on win32/Readme.txt

To assert build quality:
   on an Unixised setup:
      run make tests
   otherwise:
       There is 3 standalone tools runtest.c runsuite.c testapi.c, which
       should compile as part of the build or as any application would.
       Launch them from this directory to get results, runtest checks 
       the proper functionning of libxml2 main APIs while testapi does
       a full coverage check. Report failures to the list.

To report bugs, follow the instructions at:
