Patches 1 & 2 address bugs in stealing of guc_ids and patch 7 tests this
path.
Patches 4-6 address some issues with the CTs exposed by the selftest in
patch 7. Basically if a lot of contexts were all deregistered all at
once, the CT channel could deadlock.
Patch 3 is a small fix that is already review but just included for CI.
v2: Address comments, resend for CI
v3: Address comments in patch #7
