Commit Message

Florian Weimer April 16, 2021, 9:20 a.m. UTC 
And also the fork generation counter, __fork_generation.  This
eliminates the need for __fork_generation_pointer.

call_once remains in libpthread and calls the exported __pthread_once
symbol.

pthread_once and __pthread_once have been moved using
scripts/move-symbol-to-libc.py.
