This removes duplicate code from the chroma key filter from
when it was versioned.

ae7718a765 libobs, obs-filters: SRGB backwards compatibility
Add OBS_SOURCE_SRGB to indicate sources that support SRGB rendering. We
can use this flag to know which sources do not know how to handle SRGB,
and disable accordingly inside obs_source_main_render().

We can also use this flag to clean up the filter interface and remove
the SRGB-specific functions. We also need to disable direct rendering if
the filter source wants to render SRGB, but the parent source does not
support it.

Scenes and groups are marked as having SRGB support, and those are
internal sources that we control.

e55bfa8e20 obs-filters: Increase opacity precision
For v2 filters, switch Opacity settings from integer [0, 100] to
floating-point [0.0, 1.0] with four decimal places for granular blacks.

Also multiply alpha in shader to maintain precision.

Don't want to deal with regressions from using linear space right now.

47da18e26c obs-filters: Apply chroma key filter in linear space
Also consolidate behavior of contrast/brightness/gamma across chroma
key, color correction, and color key filters. The contrast range has
been expanded to approximtely match the range when the filter applied to
nonlinear colors.

f53df7da64 clang-format: Apply formatting
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed.  Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.

ff99ba7818 libobs: Allow filter processing function to return false
(Note: this commit also modifies the obs-filters and test-input modules)

Changes the obs_source_process_filter_begin return type so that it
returns true/false to indicate that filter processing should or should
not continue (for example if the filter is bypassed or if there's some
other sort of issue that causes the filtering to fail)

6285a47726 (API Change) libobs: Pass type data to get_name callbacks
API changed from:
obs_source_info::get_name(void)
obs_output_info::get_name(void)
obs_encoder_info::get_name(void)
obs_service_info::get_name(void)

API changed to:
obs_source_info::get_name(void *type_data)
obs_output_info::get_name(void *type_data)
obs_encoder_info::get_name(void *type_data)
obs_service_info::get_name(void *type_data)

This allows the type data to be used when getting the name of the
object (useful for plugin wrappers primarily).

NOTE: Though a parameter was added, this is backward-compatible with
older plugins due to calling convention.  The new parameter will simply
be ignored by older plugins, and the stack (if used) will be cleaned up
by the caller.

adb392e08a obs-filters: Add chroma key filter
This allows applying a mask based upon the chroma value (U/V) of a
specific color in YUV color space.  Commonly used to mask out
greenscreens and bluescreens in live video.
