This is v4 of the patches, v1 here:
https://sourceware.org/pipermail/libc-alpha/2023-January/145023.html

I added sign-off messages to my commits. Frank Barrus will have to add
them to his commit separately since I'm just sending in his patch with
minor modifications.

Diff of diffs:
v2 - use release MO when modifying g_signals in pthread_cond_common in
the first patch
v3 - add sign-off statement to commit messages
v4 - I had missed the sign-off statement in one of my patches
