When the libcamera project was started, we had no public git tree hosted
on git.libcamera.org. The problem has been addressed a while ago, and
the git.linuxtv.org libcamera repository is now a mirror of the main git
tree. The mirror is useful to benefit from the linuxtv.org automated
compile tests, but it can also confuse users who don't know where the
official version is. To try and clarify this, use the git.libcamera.org
URL consistently through the project.
This doesn't void the validatity of the linuxtv.org repository which
will continue to mirror the libcamera.org repository.

In gstreamer, when elements are created, usually a floating [1]
reference is returned which simply means, there is no ownership
transfer (yet). Once can simply check for NULL and return through
an error path, without bothering to clean up. Hence, g_autoptr is
not much of help here.
If the NULL checks have been passed successfully, elements are ready
to use. However, we must claim ownership/reference it before using
them via g_object_ref_sink().
This patch build upon this principle and removes the g_autoptr
from gstreamer test base class (gstreamer_test.cpp) whereever
necessary to tide up the code.

When creating a DRM frame buffer, the dmabufs for the planes are
imported as GEM objects. For multi-planar formats, all planes may use
the same dmabuf, which results in multiple imports. This doesn't cause
any issue at import time, as DRM detects this situation and returns the
same GEM object. However, when destroying the frame buffer, the same GEM
object ends up being closed multiple times, which generates an error.
Fix this by avoiding multiple imports of the same dmabuf for the same
frame buffer. While the issue may theoretically occur with identical
dmabufs for different frame buffers, this is quite unlikely and is thus
not addressed.
