Mike Hommey e6f05099e8 Fix a potential segfault due to weak symbols on pthreads ...

In xmlInitParser, both __xmlGlobalInitMutexLock and xmlInitGlobals are
called before xmlInitThreads, and both use pthread symbols.
__xmlGlobalInitMutexLock does so directly, without checking if the symbol
exists, and xmlInitGlobals calls xmlNewMutex, which correctly depends on
libxml_is_threaded... except libxml_is_threaded is still -1 by then...
And again, when releasing the global mutex in __xmlGlobalInitMutexUnlock,
the pthread function is called directly.

The patch changes the initialization order and make sure the functions
are available before calling them
