2023-01-16lib/video-source: Add video_source_import_buffersDaniel Scally
We need to be able to place encoded data into the sink device's bufs. To facilitate that add a video_source operation that allows the source to import buffers from the sink. Add a .import_buffers() callback so that the libcamera-source can access a sink's buffers.

2023-01-16lib: Add video_source_type enumerationDaniel Scally
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.
