Bug Description

Configuring PRIME render offloading requires changes to the X server which have been accepted upstream but are not yet present in any release. These changes do not break the driver ABI and should be safe to backport to existing X servers shipped in distributions like Ubuntu.

The required commits are:

* 7f962c70b6d9c346477f23f6c15211e749110078 - xsync: Add resource inside of SyncCreate, export SyncCreate
* 37a36a6b5b887d5c5a17a6931ceba8ad5d1bb6d5 - GLX: Add a per-client vendor mapping
* 8b67ec7cc6fda243480a5a8ca118b66242f3eb2c- GLX: Use the sending client for looking up XID's
* 56c0a71fdd94a008e5d746261f70a713c4767f93 - GLX: Add a function to change a clients vendor list
* b4231d69028adc8123801a7552b40a15ea928d1b - GLX: Set GlxServerExports::{major,minor}Version

These commits must be backported to an X.org X server of at least version 1.20, as this is the first version with support for server-side GLVND.

Yes, it's been a plan to merge them for 19.10, but I hope they'll still make it in 1.20.6.
