Never checks to see whether the source dstr is empty before copying, and
will crash if empty.

Even if the hotkey is not enabled, always allow configuration of the
hotkey.  Fixes a bug where the hotkey configuration settings would not
save if the settings were changed.

Annoyingly this means that the hotkey will still be shown to the user,
possibly confusing the user as to whether they can use it, but for the
time being it's better than having their hotkey configuration removed
each time they change the mode.

The retry interval seconds could grow exponentially large.  Limit it to
a maximum of 15 minutes between retry intervals.

Instead of just having a limited number of video file types that can be
used, allow all files types that VLC supports.

Fixes performance issues with windows 10.0.14393.0

It's supposed to look for patch segments in ascending order, from the
smallest offset to the largest offset.  Patch type/comparison is
identical to the one it's being swapped with, so only the offsets need
to be swapped.

With this change "Movies & TV" (version 3.6.2251.0) and Firefox 47.0

rtmp-services: Add Boomstream service

Instead of saying "windows versions less than 8", say "windows versions
prior to 8".

The league lobby window can apparently be captured by game capture, and
may actually be useful to capture for some people.

Makes initialization in logs a bit more clean.

SetupOutputs is already called at the beginning of the function under
circumstances where it's needed, so remove it from being redundantly
called a second time.

This data isn't typically extremely important to have logged on startup,
and it's already included as part of shutdown.  There may be scenarios
where a program crashes and that information would be lost due to the
fact that the shutdown logging never occurs, but that information is
unlikely to be useful in that scenario.

(Note: This commit also modifies coreaudio-encoder, win-capture, and
win-mf modules)

This reduces logging to the user's log file.  Most of the things
specified are not useful for examining log files, and make reading log
files more painful.

The things that are useful to log should be up to the front-end to
implement.  The core and core plugins should have minimal mandatory
logging.

libobs: Fix possible null pointer dereference

These files were heavily modified but originally written by:

Prevents the common problem of injecting in to certain processes and
getting the hook DLL "stuck":
- windows explorer
- steam
- battle.net
- gog galaxy
- skype
- uplay
- origin
- microsoft visual studio
- task manager
- league of legends lobby window
- windows 10 system settings window

Changed the first property of game capture to be a "mode" list (with
"any fullscreen window", "specific window", and "hotkey").

When hotkey mode is set, it'll add a hotkey pair to hotkey settings to
activate/deactivate game capture.  When the hotkey to activate is
pressed, it'll treat the current foreground window as the target window
similar to "selected window" mode; it'll keep trying to capture the same
window even if the window or its application closes/reopens, and will
continue to do so until deactivated via the deactivate hotkey, or until
a new window is set via the activate hotkey.

Allows enumerating IP addresses so you can select the adapter/IP from
which to stream from.

Doing something like '#if TRUE' when 'TRUE' isn't defined is the
equivalent to '#if 0' because the preprocessor evaluates an undefined
macro as 0/false.

This should be checking true or false -- not whether it's defined or
not.
