e935fcad83 Load core function pointers before checking the extension string. 
For GL versions since 3.0 the glGetString() function is deprecated or removed,
and the right way to query extensions is glGetStringi(), but that has to be
loaded first.

Also instead of searching the whole extension string n times lookup the
known extensions in a static hash table. The hash table is built with
the gperf utility.

628edd3c0b Only check OpenGL extension string if there is a non-empty string to check for. GL_VERSION_* are detected from the version info.

4744f99070 The first three lines of each core or extension file is now: name, URL and GL extension string name. For example GL_NV_geometry_program4 is available iff GL_NV_gpu_program4 appears in the extension string.
