Subject: test: Extract BufferSource class out of camera tests to libtest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The BufferSource class can be used by other tests other then the camera
buffer importer test, move it to libtest. The only changes to
BufferSource is for it to be allowed to be split in a header and source
file.

This change makes it necessary for libtest to have access to internal
libcamera headers. As the internal headers already are accessible to all
test cases this does not increase the exposure of libcamera internals to
the test cases.
