external: pack all dynamically loaded GL entrypoints into a giant struct.

On desktop this saves about 50 kB in symbols. Was done for Vulkan
already, this follows that (two years later). I need this in order to
solve the problem of static globals being unique across shared libs, and
it sounded better to export just one symbol instead of 689.
