Instead of having functions like obs_signal_handler() that can fail to
properly specify their actual intent in the name (does it signal a
handler, or does it return a signal handler?), always prefix functions
that are meant to get information with 'get' to make its functionality
more explicit.

API Removed:
- graphics_t obs_graphics();
Replaced With:
- void obs_enter_graphics();
- void obs_leave_graphics();

Description:
  obs_graphics() was somewhat of a pointless function.  The only time
that it was ever necessary was to pass it as a parameter to
gs_entercontext() followed by a subsequent gs_leavecontext() call after
that.  So, I felt that it made a bit more sense just to implement
obs_enter_graphics() and obs_leave_graphics() functions to do the exact
same thing without having to repeat that code.  There's really no need
to ever "hold" the graphics pointer, though I suppose that could change
in the future so having a similar function come back isn't out of the
question.

Still, this at least reduces the amount of unnecessary repeated code for
the time being.

Renamed:                         To:
-----------------------------------------------------------
obs_sceneitem_getscene           obs_sceneitem_get_scene
obs_sceneitem_getsource          obs_sceneitem_get_source
obs_sceneitem_setpos             obs_sceneitem_set_pos
obs_sceneitem_setrot             obs_sceneitem_set_rot
obs_sceneitem_setscale           obs_sceneitem_set_scale
obs_sceneitem_setalignment       obs_sceneitem_set_alignment
obs_sceneitem_setorder           obs_sceneitem_set_order
obs_sceneitem_getpos             obs_sceneitem_get_pos
obs_sceneitem_getrot             obs_sceneitem_get_rot
obs_sceneitem_getscale           obs_sceneitem_get_scale
obs_sceneitem_getalignment       obs_sceneitem_get_alignment

Changed:
- obs_source_gettype
To:
- enum obs_source_type obs_source_get_type(obs_source_t source);
- const char *obs_source_get_id(obs_source_t source);

This function was inconsistent for a number of reasons.  First, it
returns both the ID and the type of source (input/transition/filter),
which is inconsistent with the name of "get type".  Secondly, the
'squishy' naming convention which has just turned out to be bad
practice and causes inconsistencies.  So it's now replaced with two
functions that just return the type and the ID.

Rename source_audio to obs_source_audio to make it more consistent with
the rest of the API

Reanmed filtered_audio to obs_audio_data, to improve the naming and
prefix with obs_ for the sake with consistency with the rest of the API

For the sake of consistency, changed allow_direct_render to
obs_allow_direct_render

Prefix with obs_ for the sake of consistency

Renamed enums:
- order_movement (now obs_order_movement)

Affected functions:
- obs_source_filter_setorder
- obs_sceneitem_setorder

For the sake of naming consistency with the rest of obs.h, prefix this
structure and associated functions with obs_.

Renamed structures:
- struct source_frame (now obs_source_frame)

Renamed functions:
- source_frame_init (now obs_source_frame_init)
- source_frame_free (now obs_source_frame_free)
- source_frame_create (now obs_source_frame_create)
- source_frame_destroy (now obs_source_frame_destroy)

Affected functions:
- obs_source_output_video
- obs_source_get_frame
- obs_source_release_frame

Renamed functions:
- obs_source_getframe (rename to obs_source_get_frame)
- obs_source_releaseframe (rename to obs_source_release_frame)

For the sake of consistency and helping to get rid of the "squishy
function name" issue

Change obs_sceneitem_info structure to obs_transform_info - this
structure will not just be used with scene items in the future.

The naming here is a poor choice, a source type determines if a source
is either a regular input, a filter, or a transition.  The ID is the
actual unique identifier of a source.

Update information provided by pulseaudio plugin to pulse.

Add menu entry for obs on linux

The plugin now uses the generic name "OBS" to identify itself
to pulseaudio.

Until now the pulseaudio plugin used a placeholder icon for the
mixer to display. Now that we have a real icon installed to the
system we can use that instead.

The NSApplication delegate was changed from a setDelegate/delegate
method pair to a property, while the definition of NSApp didn't change
(its type is id while the type should be NSApplication* or similar)

Fixes jp9000/obs-studio#221

The bug here is that when conversion is active, the source video frame
is initialized with the destination height/width/format instead of the
source height/width/format.

Add obs icon and set it as window icon.

CMake changes for new real ffmpeg in debian experimental

Add libv4l2 as dependency for the v4l2 plugin

According to issue #204 on the obs-studio repository, always setting the
ABR rate control method fixes the issue.  I checked, and this was and
issue, and that does seem to fix the issue properly.

Improve module path handling

With the recent change to module handling by BtbN, I felt that having
this information might be useful in case someone is actually using make
install to set up their libraries.

Sources/Outputs/Services all use a find_* naming scheme, so it felt out
of place for the encoder to use a different naming scheme.

The OBSBasic UI will now allow the use of a subdirectory of the user
application data directory for third-party plugins.  Though I'm not
entirely sure if this ideal or not.  Regardless, this is one of the
first (of many) steps towards a plugin manager.

On windows, this is %appdata%/obs-studio/plugins
On linux, this is ~/.obs-studio/plugins
On mac, this is ~/Library/Application Support/obs-sudio/plugins

This functionality can now be handled automatically because locale can
now be freed seaparately from obs_module_unload with
obs_module_free_locale, which is called automatically when the module is
being freed.

Replaced by obs_get_version() API
