macosx/framework: Now that target "Build Everything" doesn't rebuild contrib and configure for fun, remove "Make VLC and VLCKit" target.

This reverts commit d6b5bc59.

This wasn't intended from prime time. I guess.

macosx/framework: Put configure script in a separate script (from VLCKit.xcodeproj) and use --disable-macosx-vlc-app

This may actually save some CPU cycle.

Half Patch is from jb

We shut the X11 connection down immediately anyway. This will
automatically undo all of our key grabs.

The X11 connection and the poll()'ing thread are useless if we don't
grab any single key. We still return VLC_SUCCESS to avoid an error while
VLC is being started.
