Some functions, such as uv_fs_scandir() can be called with
a NULL loop argument. In this case, it's possible that the
Windows API hasn't been initialized, leading to a crash.
This commit adds additional uv__once_init() calls to mitigate
this situation.

After the poll call, the code updates all the event objects
in the array. Instead, use the integer value returned by poll
to limit the number of epoll_event objects that are updated.
e.g. If poll returns 5, we know that we only need to update
5 event objects.

Avoid repeated wake-ups in `uv__io_poll()` when the previously watched
file descriptor has been duplicated (with `dup(2)`) and then closed.
Because epoll reports events for _file descriptions_ rather than _file
descriptors_, events on the duplicated file descriptor cause the event
loop to wake up.
Libuv then tries to unregister the event listener for the original file
descriptor but that fails with EBADF because the file descriptor is
closed.
Since libuv uses epoll in level-triggered mode, it effectively results
in a busy loop because the event is re-reported as soon as libuv calls
epoll_wait() again.
I tried hard to write a test case for this but there is no directly
observable behavior, only increased CPU usuage.

On Unix you can pass bound and even connected socket to uv_tcp_open
and it will work as expected: you can run uv_listen or other io
functions (uv_read, uv_write) on it without problems.
On windows on the other hand the function always assumes to have clean
socket and for example uv_listen will try to bind it again, and
uv_read/write will return with errors about unreadable streams
(basically invalid internal flags).
To check if socket is already bound uv_tcp_getsockname is called which
on windows returns error when socket is unbound. To further
differentiate connected one from just bound, uv_tcp_getpeername also
returns error but when target socket is not connected.

Code was assuming that the nl_pid was always equal to the process id.
As the netlink documentation says, "nl_pid is usually the PID of the
process owning the destination socket. However, nl_pid identifies a
netlink socket, not a process".
There are two cases in which this assumption breaks down. The first is
that some other part of the application has already bound a netlink
socket with a nl_pid equal to the PID of the process. The second is
Android version 5.0 where it appears that nl_pid is not always defaulted
to the PID of the process.
The result of this bad assumption is that netlink message responses to
our request are ignored due to having a bad nl_pid. We eventually run
out of messages on the netlink socket and block forever awaiting our
response.

Ensures that the user's argv is copied into a local buffer when calling
uv_setup_args. Before, the argv was simply being pointed to, which
meant that libuv could end up accessing invalid memory if the user
decided to later edit the memory at that location. It also meant that a
subsequent call to uv_set_process_title would never write more
characters than the length of argv[0].
With the new changes, argv[0] is copied into a temporary buffer and any
subsequent calls to uv_set_process_title will thus be able to copy as
many characters as the call to uv__strdup permits. Note that on *BSD
and AIX this behaviour was already in effect .
Some error checking (specifically checking the result of uv__strdup)
has been added, and calls to uv__free rearranged so that in case of
ENOMEM uv__free can't be called erroneously.
