Add functions to handle a new entry into video_source_type, representing
data with an encoding step between the source and sink. When running
through this route, buffers are allocated and mmaped on both the source
and the sink, then imported to the source to be filled before being queued
to the sink.

Add an enum to struct video_source that details the type of source
we're dealing with. This will be used to make decisions about buffer
allocation and handling in a more explicit way.
Use the video_source_type associated with a video_source to decide on
the appropriate allocation function and buffer handler at stream on time.
This is a more explicit method than relying on the presence of the
.alloc_buffers op and allows more flexibility.

We want to allow video sources whose data is generated in userspace.
Currently buffers are allocated on the V4L2-backed video source and
exported to the uvc-gadget's V4L2 device. Since a video source with
data generated in userspace will not be backed by a V4L2 device, we
allow a way for buffers to be allocated on uvc-gadget's V4L2 device.
As a corollary, the way the buffers are passed has to be changed as
well. Previously they were queued and dequeued between the V4L2 video
source and uvc and vice versa. To allow a video source not backed by
a V4L2 device, we allow an alternative flow where they are dequeued and
queued from and to uvc, and giving a chance to the video source to fill
the buffer in between.

Bringing in the meson infrastructure will enable extra warnings,
including -Wunused...
Directly reference the two locations that have known unused arguments.

We would like to be able to set the frame rate of the video source of a
stream. This patch adds such a function to set the source's frame rate
from the stream. The frame rate is set right after the format is set.
