Writes to pipes of size < PIPE_BUF are guaranteed to be atomic, so writes
larger than that will return EAGAIN if the pipe has capacity < PIPE_BUF.
Writes to eventfds will return EAGAIN if the write would cause the eventfd
value to go over the max.
In both such cases, calling Ready() on the FD will return true (because it is
possible to write), but specific kinds of writes will in fact return EAGAIN.
This CL fixes an infinite loop in splice and sendfile (VFS1 and VFS2) by
forcing skipping the readiness check for the outfile in send, splice, and tee.

ualarm(2) is obsolete. Move IntervalTimer into a test util, where it can be
used by flock tests.
These tests were flaky with TSAN, probably because it slowed the tests down
enough that the alarm was expiring before flock() was called. Use an interval
timer so that even if we miss the first alarm (or more), flock() is still
guaranteed to be interrupted.
