Oh no.

Glamor's BO cache was horribly broken, and I tried to fix it before:

  https://lists.x.org/archives/xorg-devel/2016-July/050403.html

It was then decided to drop it altogether.


The thing is, at least on the Raspberry Pi (vc4) we get 3 BO caches:
 - kernel
 - Mesa
 - GLAMOR

That's quite a lot of memory kept around "just in case".


If you insist on bringing it back, please have a thorough look at my old
series.
There was a lot of broken, as well as dead (!) code that I had to fix
to make this workable on VC4. If we reintroduce a FBO cache, at least
let's do it right this time.
