glide: Remove unneeded ae-bridge include.
build: Remove video plugin dependency on ae-imports.
ae-bridge: Remove obsolete functions.
ae-bridge: Fix inclusion guard name.
glide: Synchronize unused files with upstream.
glide: Consolidate frameskipper source files.
glide: Simplify frameskipper implementation a bit.

ticksInitialize() was never being called, hence startTicks was always
zero.  Therefore both can be removed.

Rename ticksGetTicks() -> getCurrentTicks() and make it a private
method rather than static.
glide: Initialize all frameskipper fields in constructor.
glide: Document and rename frameskipper variables for clarity.
glide: Simplify frameskipper conditionals for better readability.

And eliminate computations that aren't needed in manual frameskip.
glide: Remove unneeded frameskipper method.
glide: Change build flag ANDROID_EDITION -> USE_FRAMESKIPPER.

More general, and clearer meaning.
glide: Load frameskip settings using proper mupen64plus config API.
Merge branch 'refactor-glide-frameskipper'
glide: Add antialiasing from upstream (not implemented for GLES).
glide: Look up chroma_color uniform.

Fixes fullscreen swap bug. No more GL_INVALID_OPERATION spamming.

glide: Get rid of glEnable/glDisable(GL_TEXTURE_2D) from OGLES combiner.

Is fixed-function

  "You don't use glEnable for textures when you're using shaders.
  glEnable(GL_TEXTURE_2D) is only for fixed function pipeline, and thus
  it is not a valid operation in opengles2.0. Just remove the line
  completely."

Fixes several errors reported on Adreno devices when doing an OpenGL
trace.
glide: Use upstream screen resolution vars for screenshot.
glide: Update config defaults to match upstream.

front: Override new glide defaults.

This effectively reverts the config to what it was before the last
commit.
