Previously, we required the user to specify the expected read/write
flags for a pipe or tty. But we've already been asking the OS to tell us
what they actually are (fcntl F_GETFL), so we can hopefully just use
that information directly.

useful.

Problem:
libuv is compiled with -Wunused-result.
In two tests, read() is used for ordering and the
rc is ignored because it doesn't matter.
But -Wunused-result causes warnings in these cases.
Fix:
Provide a (very generous) check on the rc of read()
in these cases.

Previously both uv_fs_utimes and uv_fs_futimes would fall back to utimes() if untimesat() wasn't supported.
Since utimesat() has been supported since linux kernel 2.6.22, and libuv supports at minimum 2.6.32, this code can be removed.

A file descriptor that can do multiple successful write completion

Problem:
The condvar tests could pass without uv_cond_wait
(or uv_cond_timedwait) ever being invoked.
Solution:
Introduce semaphores to enforce ordering.
Now there will always be a thread waiting on the condition
when a signal() occurs.
Gotchas:
1. On Windows, waiting for a timeout may return earlier
than requested, depending on the granularity of timer ticks.
2. Timeout bounds are tuned based on our CI machines.
Bonuses:
1. I added additional test cases to complete the test matrix.
2. It seemed to me that several of the condvar tests were redundant,
because they used timing to probabilistically explore cases where there
would be "missed connections" (signal without a waiter).
Because it was not clear to me what the purpose of such tests were,
I have removed them.

This PR creates two new externally-facing APIs, uv_err_name_r() and
uv_strerror_r().
In keeping with the precedent set by POSIX, the *_r() suffix of these
two new methods indicate that the caller does the memory management and
passes in the memory that the output will be stored in, which provides
an alternative for the two existent methods (uv_err_name() and
uv_strerror()), which, when called with an unknown error code, leak a
few bytes of memory.
