Make gles2n64 the default video plugin. It is faster than glide64 on mobile devices, does not require an ini file to be present, and provides the most consistent (broken, but consistently broken) video output on various devices.
Merge branch 'master' of https://github.com/libretro/mupen64plus-libretro
Add gles2n64 plugin to Android build. Now all video plugins compile and run!
