[libc] unpoison memory returned by pipe syscall (#88942)

2024-04-18T20:36:18+00:00

The memory sanitizer doesn't recognize the results of the pipe syscall
as being initialized. This patch manually unpoisons that memory.

[libc] add remaining epoll functions, pipe (#84587)

2024-04-11T23:26:49+00:00

The epoll_wait functions need the rest of the epoll functions (create,
ctl) to be available to actually test them, as well as pipe to create a
usable file descriptor. This patch adds epoll_create, epoll_create1,
epoll_ctl, and pipe. These have tests, and the tests for epoll_wait,
epoll_pwait, and epoll_pwait2 (currently disabled) are updated to use
these newly available functions.
