Matthew Waters	e5b4f09172	glbufferpool: protect release_buffer from multiple concurrent access ... If two different threads attempt to release buffers at the same time, then the keep-alive-slightly-longer GQueue may become corrupted. Guard against that with some locking.

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.
