On AIX with the native xlC compiler, the compiler supports sync
compare swap and compare in two flavors:
1 __compare_and_swap
2 __compare_and_swaplp

This differs from the gcc version of this function in name. The
second version of this function supports 8-byte boundary for
a doubleword. Therefore, the macro logic checks:
if (AIX OS AND using xlC compiler)
if (64bit)
__compare_and_swaplp /* 64 bit version */
else
__compare_and_swap

win: fix unsavory rwlock fallback implementation

Before this patch an uv_mutex_t (backed by a critical section) could be
released by a tread different from the thread that acquired it, which is
not allowed. This is fixed by using a semaphore instead.

Note that the affected code paths were used on Windows XP and Windows

In FreeBSD if connect is called and the queue of pending connections(backlog)
is full, the call is automatically rejected with ECONNRESET. In the tests, 100
connections were tried and the backlog of both servers is 12, so the error.

To fix ipc_listen_before_write and ipc_listen_after_write, the backlog of the
server has been increased to 128.

tests: fix fs tests run w/o full getdents support

fs_access, fs_async_dir and fs_symlink_dir could fail when the
filesystem where the tests are run does not fully support getting the
file type via getdents. Having getdents support does not imply that the
underlying filesystem fully supports what is necessary for these tests
to have passed prior to this commit. So the failing tests were updated
to check for UV_DIRENT_FILE as it did previously but it will also check for
UV_DIRENT_UNKNOWN as well to handle the filesystems that do not fully support
getting the file type via getdents. For OS X and Windows, which are
known to fully support getting the file type, the tests work as they did
before and will not check for UV_DIRENT_UNKNOWN. We could/should update the
preprocessor directive that chooses "rigorous" or "lax" checks
accordingly when we learn of new environments that should always do the
original "rigorous" checks.

fs: fix bug in sendfile for DragonFly

The code made an implicit assumption that the 'len` variable passed
to the sendfile(2) syscall is not modified by the operating system
in case of an error other than EAGAIN or EINTR.

The man page leaves this unspecified on FreeBSD, DragonFly and
Darwin, so better check the error code which returns a valid
value in `len` explicitly (only EAGAIN and EINTR).

This fixes the test case for sendfile on DragonFly.

threadpool: fix thread starvation bug

Commit 0f1bdb6 ("threadpool: send signal only when queue is empty")
introduces a regression where work is not evenly distributed across
the thread pool because the work queue's condition variable is only
signalled when the queue is empty, even when there are waiting workers.

It doesn't turn into outright deadlock because there is always
at least one thread making forward progress but it does degrade
throughput, sometimes massively so.

Signalling whenever there are waiting workers fixes the throughput
issue while still keeping the number of uv_cond_signal() calls low,
which was the motivation for commit 0f1bdb6.
