65536f25dd meson: Update option names to omit disable_ and with- prefixes
Also yield common options to the outer project (gst-build in our case)
so that they don't have to be set manually.

2bbe877a6e v4l2: rely on gst_v4l2_dup() to set no_initial_format and keep_aspect
gst_v4l2_dup() will now take care of setting
v4l2capture->no_initial_format and keep_aspect instead of doing it
manually.

Fix a typo as keep_aspect was set twice on v4l2output but never on
v4l2capture.

2d774554e9 v4l2object: Disable DMABuf for emulated formats
libv4l2 does not prevent exporting DMABuf even when emulated formats are
in use. As a side effect, userspace ends up with buffers of the original
formats which will cause issues.

ebf8a6d0c0 v4l2object: Only use BT2020_12 for BT2020 v4l2 colorspace
BT2020_12 is not represented in V4L2, so drivers providing full colority
for BT2020 will set V4L2_XFER_FUNC_709 transfer function. To fix the
issue, we bump this to BT2020_12 if the resoltion is 4K, but we should
only do that if the colorspace is BT2020 to start with, otherwise it's
not possible to use normal BT709 for 4K 8bit formats.

dd1c5aed65 v4l2object: Always set the colorimetry in S_FMT
So far we were only setting colorimetry for OUTPUT devices (v4l2sink or
m2m sink pad). This prevented selecting through caps negotiation the
colorimetry for CAPTURE devices (v4l2src or m2m src pad). This is rarely
selectable, but trying is harmless.

For a later release, once the elements have more testing, we can

21b01acef1 v4l2src: Maintain downstream caps order
The g_list_insert_sorted() will behave like prepend when the compare
function returns 0. In our case, we want to maintain the order hence
append. This fixes this issue and improve the sorting algorithm to make
a 10x10 prefered over 10x200 with a preference of 10x8 (and similar
cases which was badly handled). This fixes generally fixes issue were a
sub-optimal format / size is picked.

This is problematic in the current design at it seriously slow down
startup of applications. As of now, no known application uses the
colorimetry and the interlace-modes for anything (the two fields that
won't be probed). So let's disable it, in the long term we'll try and
find a way to interact with the provider so applicaiton could opt-in
these slow probing methods for more advance configuration.

4026211154 v4l2object: Don't use mmap64 if off_t is 64-bit
The difference between mmap and mmap64 is the type of 'offset' argument.
mmap64 always uses a 64-bit interger as offset, while mmap uses off_t,
whose size can vary on different operating systems or architectures.

However, not all operating systems support mmap64. Fortunately, although
FreeBSD only has mmap, its off_t is always 64-bit regardless of
architectures, so we can simply use mmap when sizeof(off_t) == 8.

5e05cadb17 v4l2videodec: Handle drivers that only round up height
Commit 1f31715c98 ("v4l2videodec: use visible size, not coded size,
for downstream negotiation filter") added support for removing the
padding obtained as the difference between width/height from G_FMT and
visible width/height from G_SELECTION from the probed caps obtained
via TRY_FMT.
This patch fixes the padding removal for drivers that only round up
height, but not width, to the padded frame size. This might happen
because horizontal padding can be handled by line stride (bytesperline),
but there is no such thing as plane stride in the V4L2 API for
single-buffer planar formats.

57d7ae8496 v4l2allocator: Add support for data_offset
In MPLANE mode, the driver may set data_offset, which represent some
padding at the start of the buffer used internally. This portion of the
data need to be skipped, though it is included in bytesused.

This patch removes frame size sanity check as the method used will no
longer work. This check was simply there to help detect broken kernel
drivers. It would be re-implement by estimating the plane size, which is
not totally trivial and may be too much work for a simple debug check.
