Rob Clark 964efdfba9 egl+libsync: Add check for valid fence-fd 
Debugging fd mix-ups (ie. where, possibly via close()ing the original
fd, etc, you end up with something that is a valid fd but not a valid
*fence* fd) can be difficult.  Fortunately we can use the FILE_INFO
ioctl, which will return an error if the fd is not a fence fd.

For android, we instead use the libsync API, which does a similar thing
on modern kernels, but has a fallback path for older android kernels.

Note that the FILE_INFO ioctl has existed upstream since at least prior
to destaging of sync_file.

README.md

The Android NDK doesn't come with enough of the platform libraries we need to build Mesa drivers out of tree, so android_stub has stub versions of those library that aren't installed which we link against, relying on the real libraries to be present when the Mesa driver is deployed.
