jp9000 cd97ce2a17 libobs: Add source output flag OBS_SOURCE_DO_NOT_DUPLICATE
Certain types of sources (display captures, game captures, audio
device captures, video device captures) should not be duplicated.  This
capability flag hints that the source prefers references over full
duplication.

jp9000 6ad8df8adb (API Change) libobs: Use single func for base effects
API removed:
--------------------
gs_effect_t *obs_get_default_effect(void);
gs_effect_t *obs_get_default_rect_effect(void);
gs_effect_t *obs_get_opaque_effect(void);
gs_effect_t *obs_get_solid_effect(void);
gs_effect_t *obs_get_bicubic_effect(void);
gs_effect_t *obs_get_lanczos_effect(void);
gs_effect_t *obs_get_bilinear_lowres_effect(void);

API added:
--------------------
gs_effect_t *obs_get_base_effect(enum obs_base_effect effect);

Summary:
--------------------
Combines multiple near-identical functions into a single function with
an enum parameter.

jp9000 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.

jp9000 e20ec366b2 Make capture sources w/o alpha use opaque effect
This fixes an issue primarily with filter rendering: when capturing
windows and displays, their alpha channel is almost always 0, causing
the image to be completely invisible unintentionally.  The original fix
for this for many sources was just to turn off the blending, which would
be fine if you're not rendering any filters, but filters will render to
render targets first, and that lack of alpha will end up carrying over
in to the final image.

This doesn't apply to any mac captures because mac actually seems to set
the alpha channel to 1.

jp9000 233004631f linux-capture: Mark captures as custom drawn
The linux window and monitor captures draw in a custom way, therefore
they must be marked as types of sources that do custom rendering.

jp9000 b277f2b737 Don't update video of sources if not displaying
This is a bit of an optimization to reduce load a little bit if any of
the video capture sources are not currently being displayed on the
screen.  They will simply not capture or update their texture data if
they are not currently being shown anywhere.

The mac and window game capture sources don't really apply due to the
fact that their textures aren't updated on the source's end (they update
inside of the hooks).

Add xcb screen structure to the source data for later use in the porting
process.

Add an internal function to check for all the extensions needed by the
xshm capture to work.

fryshorts cc56634e91 linux-xshm: Handle missing screens.
This adds a check to the screen enumeration in order to handle missing
screens by adding them to the list but disabling them.

fryshorts 67ca94f7e4 linux-xshm: Add server property.
This adds a property to the source properties which lets the user
specify the X server to capture from. Since this is probably something
thats only useful under certain circumstances it is implemented as
an advanced setting which is only shown when the corresponding option
for advanced settings is checked.

fryshorts 04a7db867f linux-xshm: Refactoring of setup code.
This moves the code to start/stop the capture to respectively named
function in order to clean up the update function.
This means that the capture is stopped/started whenever the settings are
changed. While this increases overhead for some settings, this will also
enable future settings that require a full restart of capture process.

fryshorts a4d09fe742 linux-xshm: Small change for texture update function.
This removes the entering/leaving of the graphics context from this
function and requires the calling code to make sure the context is
present.

fryshorts cc52b432e7 linux-xshm: Improve geometry update function.
This adds the screen id from the source properties to the source
struct and changes the geometry function to use that value instead
of requiring the settings object of the source.

fryshorts 08c9f39220 linux-xshm: Use macro for logging.
This adds a macro to automatically prepend the plugin name to debug
statements like it is done in other plugins.

fryshorts 1a51d5fab7 linux-xshm: Improve source struct.
This adds documentation to the source struct and moves one bool to the
end to avoid a hole due to alignment.

jp9000 c9df41c1e2 (API Change) Remove pointers from all typedefs
Typedef pointers are unsafe.  If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data.  I admit this was a fundamental mistake that must
be corrected.

All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.

This does not break ABI though, which is pretty nice.
