I unintentionally stored the windows version in a 16bit format rather
than an 8bit format.

Certain plugins/modules that are loaded on windows may be dependent on
libraries that are located in the same directory as the module in
question.  This makes is so that LoadLibrary will also search for
dependent libraries for that module in the module's directory.

Adds functions to get or set the current working directory.

When globbing for modules, the intent was to ignore the . and ..
directories that might also be included in the glob search.  It was
mistakenly doing a string compare on the 'path' variable which contains
the full path, rather than the 'file' variable which just contains the
found file itself, so the string compare always failed.

If on windows/linux, make the plugin search path also include the
architecture bits for its binary search path.

rtmp-services: Update twitch.tv ingests

Fixes issues using DepsPath(32|64), was using ${lib_suffix} instead of
${_lib_suffix} so 32/64-sepcific directories wouldn't work properly.
Also the DepsPath environment/cmake variable wasn't specified for the
library search.

Also added the same dependency search paths for libfdk (if someone wants
to use it on windows for whatever reason)

Fixes for Authenticated RTMP streams

This fixes "warning: unused parameter 'maxsize' [-Wunused-parameter]"
introduced when authentication was turned on.

This was casting the return type to bool, which caused any non-zero
return code be converted to 1.

This is writing a string which LoadLibraryW can read in the target
process; it's not being executed so there's no reason to mark it as
executable.

Update Beam's recommended broadcast settings

Closes jp9000/obs-studio#453

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.

This fixes a bug where scene collections would not properly save when
modifying them.

This adds a function that allows saving the project now instead of
deferring it.

This bug corrupted the audio headers due to mis-use of operator
precedence.

Uses the sample rate the audio encoder is running at for ffmpeg muxing
(in case the audio sample rate had to be changed by the encoder)

In case the encoder has to use a different sample rate (due to the
sample rate being unsupported), we need an API function for the encoder
to get the sample rate that the encoder is actually running at.

When an audio filter is applied to a video source that also has
accompanying audio, it would cause the video from the source to stop
rendering.

The original code this was from was to prevent audio-only sources from
rendering video, but I neglected to make sure that this would not apply
to filters, and thus when an audio filter is on a source with video, the
code would kill the video.
