Libuv loaded and unloaded the Core Services and Application Services for
every call to uv_set_process_title().
Change that to load them on the first call to uv_set_process_title() and
delay unloading until libuv is unloaded.
Speeds up process_title_threadsafe by about 10x on my system.

Encode domain names before passing them on to the libc resolver.
Some getaddrinfo() implementations support IDNA 2008, some only
IDNA 2003 and some don't support i18n domain names at all.
This is a potential security issue because it means a domain name
might resolve differently depending on the system that libuv is
running on.

The test runner inserted a 250 ms delay to give helper processes time to
settle. That's intrinsically race-y and caused tests to intermittently
fail on platforms like AIX.
Instead of a fixed delay, pass a file descriptor to the helper process
and wait until it closes the descriptor. That way we know for sure the
process has started.
Incidentally, this change reduces the running time of the test suite
from 112 to 26 seconds on my machine.

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.

A file descriptor that can do multiple successful write completion
requests in a row will starve the loop because it will keep feeding
the write_completed_queue. This fix will only process items on the
write_completed_queue once per event loop (in uv__run_pending).
Any new items on the queue will be processed in the next loop.

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.

Libuv does not support multiple handles watching the same file
descriptor. That condition is caught by an assert but it's detached
from the call site and therefore not always trivial to track down.
This commit turns cases where we can easily detect duplicates into
runtime `UV_EEXIST` errors. More work is needed to catch _all_ cases.
