Like the previous commit, except now the signal mask is reset instead
of the signal disposition. This does open a race window where blocked
signals can get delivered in the interval between the pthread_sigmask()
call and the execve() call (and may end up terminating the process) but
that cannot be helped; the same caveat applies to the previous commit.

Signal dispositions are inherited by child processes. Libuv itself
does not touch them (if you don't use uv_signal_start(), that is)
but the embedder might and probably does in the case of SIGPIPE.
Reset the disposition for signals 1-31 to their defaults right before
execve'ing into the new process.

atomic_cas_ptr() is for compare-and-swap pointer addresses.
So when building 64 bit:
1. `ptr` is used casted to a pointer value (4-byte into 8-byte).
2. atomic_cas_ptr reads 8-byte at `ptr` and returns
In the case of `uv_async_send`, if handle->pending is 0, cmpxchgi()
actually returns the value of the 4-bytes past handle->pending,
causing uv__async_send to never be called.
The modified test-async-null-cb.c hangs at uv_run in this case.

Added the uv_loop_fork() API that must be called in a child process to
continue using an existing loop. Internally this calls a uv__io_fork
function for each supported platform, similar to the way
uv__platform_loop_init works.
After this call, existing and new IO, async and signal watchers will
contiue working as before on all platforms, as will the
threadpool (although any threads it was using are of course gone).
On Linux and BSDs that use kqueue, existing and new fsevent watchers
will also continue to work as expected. On OS X, though, directory
fsevents will not be able to use the optimized CoreFoundation path if
they had already been used in the parent process, instead falling back
to the kqueue path used on other BSDs.
Existing fsevent watchers will not function on AIX or SunOS. This
could be relatively easily fixed by someone with AIX knowledge in the
future, but SunOS will require some additional work to keep track if
the watchers.
A new test file, test/test-fork.c, was added to contain fork-related
tests to verify functionality in the child process.

This patch enables querying and setting the process title on AIX.
libuv takes ownership of the memory for argv and returns a deep copy
of the array and its contents.
It also enables the process_title test case.
The process title can be changed on AIX but is handled differently
to Linux/Mac. Commands like ps read the original argv array passed
to the process instead of the memory at argv[0]. To change the process
title we need to update argv[0] to point at a new string and set
argv[1] to NULL (if it exists). This means the process title
can be set to a string of any length.
