Nicolas DufresneandLaurent Pinchart 0c4147c3b6 gst: libcamerasrc: Implement timestamp support 
This is an experimental patch adding timestamp support to the libcamerasrc
element. This patch currently assume that the driver timestamp are relative to
the system monotonic clock. Without a reference clock source, the timestamp are
otherwise unusable, and without timestamp only minor use case can be achieved.

Nicolas DufresneandLaurent Pinchart d1d1348228 gst: libcamerasrc: Implement initial streaming 
With this patch, the element is now able to push buffers to the next
element in the graph. The buffers are currently missing any metadata
like timestamp, sequence number. This will be added in the next commit.

Nicolas DufresneandLaurent Pinchart 5d6db0936f gst: pad: Add method to store retrieve pending buffers 
These will be useful for streaming. The requestComplete callback will
store the buffers on each pads so that the _run() can pick them up
and push them through the pads from a streaming thread.

Nicolas DufresneandLaurent Pinchart 71a28f9593 gst: Add pads to the source 
This simply adds the boiler plate for pads on the source element. The
design is that we have one pad, called "src", that will always be
present, and then more pads can be requested prior in READY or less
state. Initially pads have one property "stream-role" that let you
decide which role this pad will have.
