[PATCH libX11] Always initialise thread support

[Daniel Stone]

Make XOpenDisplay always call XInitThreads when opening a display, thus
guarding it against possible disaster scenarios like calling
XOpenDisplay without XInitThreads, then passing the Display pointer into
an EGL library which uses threads.  Or any of the other five similar
failure scenarios I've seen just this week.
