Deferred load is used specifically for macOS systems to ensure that Qt
and CEF do not load at the same time. This causes a slight bit of a
delay in loading the scene after the UI has loaded. This is not
necessary for other operating systems, so revert to the older load code
in the case of different systems.
Add a new algorithm to calculate the true-peak. It implements the
Whittaker- Shannon interpolation from four samples to create 4
intermediate samples (5 x oversampling) inbetween the middle two
samples.
With 4 samples and 4 intermediate samples the algorithm can be
implemented as a 4x4 vector-matrix cross product, which is ideal for
SSE.
I've also replaced the sample-peak algorithm using SSE as well to
improve performance.

Adds obs_add_raw_video_callback() and obs_remove_raw_video_callback()
functions which allow the ability to get raw video frames without
necessarily needing to create an output.
Reduces GPU usage when encoding is not active. Does not perform color
conversion, frame staging, or frame downloading unless encoding is
explicitly active.
Audio controls in OBS Mixer and Advanced Audio Properties window are not
sorted at all. Every time OBS is restarted they get shuffled (Jim note:
This is due to json object hashing). The order of these controls is
additionally not consistent between the mixer and the advanced audio
properties window.

The filters array should not be accessed without locking the filter
mutex. This locks the filter mutex, grabs a reference to the first
filter, unlocks the mutex, renders the filter, and then releases the
reference.

Add Selected and Hidden Array Values
Let developers get and set whether items in an editable list are hidden
or selected. May be useful in when editable lists are modified and
handled in a callback. Especially when edit button callbacks are used.

Due to the commit 34c14829b6176248970bb, source loading is now deferred
to after OBSInit(), which would cause saved scene/source projectors to
no longer load on startup. This fixes that issue by moving the
OpenSavedProjectors call to OBSBasic::Load().
After you call av_frame_alloc(), ffmpeg expects you to fill in certain
fields on the frame, depending on whether it's an audio or video frame.
obs-ffmpeg did this in the two places where it allocates video frames,
but not where it allocates audio frames. On my system, using trunk
ffmpeg and the Opus codec, this causes OBS to crash while calling
avcodec_send_frame, ultimately because av_frame_copy fails due to
'dst->format < 0' (as 'format' stays at the default of -1), causing a
null pointer to be added to a buffer queue, which later gets
dereferenced.
Oddly, the fields in question can just be copied directly from
corresponding fields in the AVCodecContext, but I don't see any ffmpeg
API to automatically copy all relevant fields, and all the examples I've
seen do it by hand. So this patch does the same.
Solves crash when a user tries to paste filters without selecting a
source or when pasting filters from a deleted source. This commit
checks if both sources are still valid before pasting.
This addresses Mantis Issue 1220
(https://obsproject.com/mantis/view.php?id=1220).
When an user launches a multiple instance of obs and don't use the -m
flag, wait until the confirmation to launch to create a new log file.
This avoids a short log with no information when using the Help ->
Update Last Log.

The log output of the travis CI for macOS is unreasonably large. This
reduces the verbosity of the output and reduces the size of the build
logs significantly.
Adds an alternative means of isolating the CEF initialization process
from Qt's initialization process. This is an unpleasant hack, but is
far more preferable than isolating the entire browser plugin to a
separate process and overly complexifying the browser plugin to the
point to where no one wants to touch the plugin or contribute to it.
