EGL contexts and surfaces are resources of displays. They should be
managed by displays. This commit adds a bunch of functions to
egldisplay.c to help establish the links between contexts/surfaces and
displays. How links are established is considered opaque outside
display. Functions like _eglGetSurfaceHandle or _eglLookupSurface are
therefore moved to egldisplay.c, with some small modifications.
The idea is also extended to display. That is, displays need to link to
themselves to be looked up.
This commit only adds the functions. A commit to use them should
follow.

EGL allows multiple current contexts, as long as they are bound to
different client APIs.

This commit introduces a "current" system to manage per-thread info. It
uses TLS, if GLX_USE_TLS is defined, or pthread, if PTHREADS is defined.
If none of them are defined, it uses a dummy implementation that is just
like before.

In EGL 1.4 the opaque EGLContext type is a pointer so we can just cast
between public EGLContext handles and private _EGLContext pointers.

Rename eglShowSurfaceMESA to eglShowScreenSurfaceMESA.

Redo _eglInitContext() to do error checking, attribute list parsing, etc.

Seems to be mostly working. Not all of egl API is implemented.
