This is specific to when the waylandsink is not being embedded. In
this patch we pass the render lock to the window so it can safely
call gst_wl_window_set_render_rectangle() with the new size.
https://bugzilla.gnome.org/show_bug.cgi?id=722343
We already take the render lock from the wlqueue thread in some other
place which indicates that there is no use of this atomic instead of
a proper locking mechanism.
When we don't have a viewporter (scaling support), we can't use the
1x1 scaleup image trick. Instead, we need to allocate a buffer with
the same size as the area that need to have black background.
Currently dx9screencapsrc prints a verbose warning in case the screen
index is out of range for the current number of detected monitors. This
value is then dropped.
However there is no initial indication (beside the console print) if it
worked or not. This may result in capturing an unwanted screen as it
would capture the last set index that was not rejected.
This patch sets the index regardless. Instead, the element throws an
error when it tries to run or getting caps for an invalid index.

The linker flags for several plugins (dashdemux, mssdemux, hlsdemux) are missing
$(GST_PLUGINS_BASE_LIBS), so add them so they can find -lgsttag and -lgstapp.

This add support for non-standard strides to be used. Note that
some extra work is needed for multi-plane format which may have
a different GstMemory object per plane. This is not currently a
problem since SHM interface is limited to 1 memory.
The buffer pool API does not allow multiple of owner. This otherwise
lead to error when renegotiation take place. Aso consider the
allocation query "need_pool" boolean.
The default value of D-bit is changed to TRUE so discontinuity
is set for initial request and seek request as well.
Only set the e_bit flag for the CUSTOM_DOWNSTREAM event if
a cached buffer exists.

Fixes an assertion when moving from passthrough to non-passthrough
Without an explicit reconfigure, glfiter won't have created the GL
resources such as the FBO, GL bufferpool, etc and basetransform will
allocate sysmem buffers instead.
This makes the viewporter interface optional. The end result is
obviously far from optimal, though it greatly helps testing on older
compostitors or gnome-wayland. We can make it strictly needed later when
this new interface get widely adopted.
e.g. passing with_gl_api=gles2 would still build the glx code but not be
linking against the libGL library which is where the glX* functions are
located and would result in a linker error.
Solved by checking for the libGL library if either opengl or glx may be
needed and then disabling the corresponding deps as requested.
In most display sink, the logic is to use as much as possible
of the given window. In this case, the window is the screen,
hence it's logical to scale up.

The source region was scaled for display before being passed
to drmModeSetPlane, which resulted in a portion of the video
being cropped. While when crop meta was present, the rectangle
was not centered since we where using unscaled width/height.

Some kms drivers demands specific pitches over the ones calculated by
GstVideoInfo. For example, intel driver demands strides round up 64.
This patch queries the driver for the prefered pitch and overwrites it
in the pool's GstVideoInfo structure.
