For some reason librtmp treats a close message as a request to reconnect.
It does this syncronously, and uses the same event processing so that
another close request will continue the cycle until the stack is exhausted
and the application crashes.

Apple wants to get people to move over to their own crypto APIs instead
of using OpenSSL, so disable the warning in the files where OpenSSL is
used for the time being.
With no stream key, no streams were actually being created.
This is a crazy configuration anyway, but it resulted in OBS getting
stuck in the "Connecting" state with no way to cancel.
We now just use the blank key and hope for the best.
Reinstate flag checks in RTMP_Close that were erroneously removed.
Clear out the Link state before we establish a new connection. There is
too much state carried around during authentication that has no good
place to clear it in librtmp, which assumes a clean structure when the
connection is initially established.
Authentication code has been updated as per the changes to support
multiple streams.
Authentication is now also enabled by default, and should be a no-op
if the server does not request authentication or username and password
details are not provided.
This was caused to do the new RTMP code that added support for multiple
streams; the stream index needs to be reset on RTMP_Close otherwise it
will keep using the wrong stream information.
On windows, for whatever reason sockets use the SOCKET type which is not
a signed integer. Still, even though it's not a signed integer, -1 is
used to indicate an invalid socket, but the way you use it is via
microsoft's fabulously dumb little INVALID_SOCKET define, so we have to
make librtmp use that instead.
Certain RTMP services will support multi audio tracks via RTMP. This
updates librtmp with custom code that enables multiple streams per
connection to be used; each subsequent stream typically containing extra
audio tracks. The audio encoder names are used to indicate the names of
tracks, and the name of the tracks are used for the stream keys for
those subsequent tracks.
Note that this is a somewhat heavily modified custom version of librtmp.
I modified all the platform specific code that we were using for the
OBS1 to make it platform-independent.
I don't really like the code in this library, but it works well enough,
so I can't really fault anyone for it. It's just very.. unclean. Even
for a C library, quite unclean. Some parts are also a little less safe
than I'd prefer as well.
