Map the application visibile formats::MJPEG format to the V4L2_PIX_FMT_JPEG
format.
Both V4L2_PIX_FMT_JPEG and V4L2_PIX_FMT_MJPEG to the same libcamera
MJPEG format.

The V4L2_PIX_FMT_JPEG and V4L2_PIX_FMT_MJPEG formats are under-specified
and are used interchangeably by kernel drivers.
Map both of them to formats::MJPEG and use the newly re-introduced
V4L2VideoDevice::toV4L2PixelFormat() to map to the one actually used by
the video device.

The toV4L2PixelFormat() function selects which V4L2 format variant to
use (contiguous planes vs non-contiguous version) by using video device
multiplanar API from the capabilities.
The isMultiplanar() function however verifies if the video device uses
the singleplanar or the multiplanar V4L2 API, something which is
unrelated to the format variant to use.
Add a 'multiplanar' flag, which defaults to false, to the
toV4L2PixelFormat() function to allow explicit selection of the format
variant.

Now that V4L2PixelFormat::fromPixelFormat() returns a list of formats
to chose from by checking which ones are actually supported by the video
device.
The first format found to match one of the device supported ones is
returned.
As V4L2VideoDevice::toV4L2PixelFormat() is a const function which uses
other functions of the class, those functions has to be made const as
well.
In particular:
- enumPixelformats() and enumSizes() do not modify the class state and
can safely be made const.
- formats() uses the above functions and does not itself modify the
class state and can be made const
- add a const version of V4L2Device::ioctl() to be used by the now const
functions

This is a partial revert of commit 395d43d6d75b ("libcamera:
v4l2_videodevice: Drop toV4L2PixelFormat()")
The function was removed because it incorrectly maps non-contigous V4L2
format variants (ie V4L2_PIX_FMT_YUV420M) to the API version supported
by the video device (singleplanar API and multiplanar API). It was
decided at the time to remove the function and let its users call
directly V4L2PixelFormat::fromPixelFormat() which accepts a
'multiplanar' flags.
As we now aim to associate multiple V4L2PixelFormat to a single
libcamera format, it is necessary to verify which of them is actually
supported by the video device.
Hence re-introduce V4L2VideoDevice::toV4L2PixelFormat() and convert all
the V4L2PixelFormat::fromPixelFormat() users to use it.
The V4L2 compatibility layer is the only outliner as it doesn't have a
video device to poke, hence it still uses
V4L2PixelFormat::fromPixelFormat() and defaults to the first format.
Next patches will implement the device format matching logic and handle
the non-contiguous plane issue in V4L2VideoDevice::toV4L2PixelFormat().

As we prepare to associate multiple V4L2 FourCC to a single libcamera
format, make the V4L2PixelFormat::fromPixelFormat() return a list of
formats and convert all its users to pick the first one.
This change prepares to re-introduce V4L2VideoDevice::toV4L2PixelFormat()
which will instead match the list of V4L2 FourCC against the formats
supported by the video device.
While at it, reword the V4L2PixelFormat::fromPixelFormat() documentation
to distinguish between planar/multiplanar and contiguous/non-contiguous.

The OpenGL ES shading language has no default precision declared
implicitly for floats in fragment shaders. The lack of an explicit
default precision results in shader compilation errors.
Specify a default precision of mediump for floats. This matches the
other fragment shaders, and is guaranteed by the OpenGL ES shader
language specification to be supported by all devices, while the higher
precision highp is optional.

The logic used to match asynchronous image and embedded buffers was being overly
aggressive by possibly allowing an unmatched image buffer to be sent to the IPA
if the matching embedded buffer had not yet been dequeued. This condition only
occurs when the system is heavily loaded and dropping frames.
Fix this by holding image buffer in the queue during these conditions until the
next embedded buffer dequeue event.

Previously, ControlList::get<T>() would use default constructed objects to
indicate that a ControlList does not have the requested Control. This has
several disadvantages: 1) It requires types to be default constructible,
2) it does not differentiate between a default constructed object and an
object that happens to have the same state as a default constructed object.
std::optional<T> additionally stores the information if the object is valid
or not, and therefore is more expressive than a default constructed object.

Support the X variants of the RGB pixel formats alongside the
equivalent Alpha component based versions.
The QImage::Format_RGB32 and QImage::Format_RGBX8888 formats only
specify that the alpha component must be 0xff. While the Qt
documentation doesn't guarantee that the alpha value will be ignored by
consumers, this seems to be the implemented behaviour, at least when
rendering with QPainter::drawImage().
The existing use of QImage::Format_RGBA8888 is updated to use the

Commit 6f539a6d2fa9 ("delayed_controls: Remove reduandant firstSequence_")
removed support for frame number start offset from the DelayedControls
class, as it is now guaranteed that the first sequence number as it comes
from the V4L2VideoDevice will always be 0.
However the delayed_controls.cpp unit still has two tests that passes
a non-zero first sequence number to the DelayedControl class, causing
the test to spin forever and consequentially fail.
Remove the two tests from the unit to fix this.
The first removed test was testing the class against frame start
sequence numbers greater than zero and can safely be removed.
The second test was instead validating the class against sequence number
overflow, which is now not possible to test anymore as the DelayedControls
class now assumes 0 as first frame sequence number.

The task run function races with two other threads that want to resume
the task: the requestCompleted() handler and the buffer-notify signal
handler. If the former queues completed requests or the latter queues
back buffers to the pool, and then resume the task, after the task run
handler checks the queues but before it attemps to pause the task, then
the task may be paused without noticing that more work is available.
The most immediate way to fix this is to take the stream_lock in the
requestCompleted() and buffer-notify signal handlers, or cover the whole
task run handler with the GstLibcameraSrcState lock. This could cause
long delays in the requestCompleted() handler, so that's not a good
option.
Instead, pause the task unconditionally at the beginning of its run
function, and track while processing buffers and requests if the task
needs to be resumed. It may also get resumed externally by the
buffer-notify signal handler or the request completion handler, which
are guaranteed not to race due to the lock taken by the gst_task_pause()
and gst_task_resume() functions.
