Matthew Waters 9d867356df gl/bufferpool: add configuration to extend buffer lifetime before reuse 
Fixes a potential GPU stall if an immediately freed texture/buffer is
attempted to be reused immediately by the CPU, e.g. when uploading.

Problematic scenario is this:
1. element does GPU processing reading from texture
2. frees the buffer back to the pool
3. pool acquire returns the just released buffer
4. GPU processing then has to wait for the previous GPU operation to
   complete causing a stall

If there was a reliable way to know whether a buffer had been finished
with across all GPU drivers, we would use it.  However as that does not
exist, this workaround is to keep the released buffer unusable until the
next released buffer.

This is the same approach as is used in the qml (Qt5) elements.
