Subject: egl: Add _eglPreloadDrivers.

It can be used to load the user driver specified by EGL_DRIVER, or a set
of drivers specified by EGL_DISPLAY, or the default driver, and in that
order.

Subject: egl: Rename _EGL_PLATFORM_X to _EGL_PLATFORM_POSIX.

The macro is used to determine if dlfcn.h or dirent.h is available.
POSIX is a better name than X in such case.
