Now that we have camera sensor control application delay values in
the CameraSensorProperties class, remove the duplicated definitions
in the RPi IPA's CameraSensorHelpers and update the pipeline handler
to use the values from CameraSensorProperties.

This is the minimum permitted difference between the frame length and
coarse exposure (both measured in lines). The correct value, taken
from the datasheet, is 48.

The frameIntegrationDiff value should be 25, otherwise we see invalid
frames when integration times are set to large values.

The terms "shutter" and "shutter speed" are used through libcamera to
mean "exposure time". This is confusing, both due to "speed" being used
as "time" while it should be the inverse (i.e. a maximum speed should
correspond to the minimum time), and due to "shutter speed" and
"exposure time" being used in different places with the same meaning.
To improve clarity of the code base and the documentation, use "exposure
time" consistently to replace "shutter speed".
This rename highlighted another vocabulary issue in libcamera. The
ExposureModeHelper::splitExposure() function used to document that it
splits "exposure time into shutter time and gain". It has been reworded
to "split exposure into exposure time and gain". That is not entirely
satisfactory, as "exposure" has a defined meaning in photography (see
https://en.wikipedia.org/wiki/Exposure_(photography)) that is not
expressed as a duration. This issue if left to be addressed separately.

The IMX327 sensor is largely compatible with the already supported
Sony IMX290 so we can reuse the same helpers for the analogue gain
conversion functions.

OV7251 is a mono VGA global shutter sensor that has a mainline
driver and works with libcamera.
Add the supporting files for it. The tuning is copied from OV9281.

As described in the coding style document, libcamera favours <cmath>
over <math.h>. Replace the last few occurrences of the latter with the
former in the Raspberry Pi IPA and adapt the code accordingly. In some
cases, the <math.h> include is simply dropped as it isn't needed.

Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.
The change was generated with the following script:
----------------------------------------
dirs="include/libcamera src test utils"
declare -rA patterns=(
['c']=' \* '
['cpp']=' \* '
['h']=' \* '
['py']='# '
['sh']='# '
)
for ext in ${!patterns[@]} ; do
files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done
done
----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

The imx290 produces a single unusable frame on startup and mode switch.
This is signalled to the IPA in the mode switch case, but not the
startup case. Fix this.

The imx708 must drop a single frame on startup - but only when in HDR
mode. Non-HDR modes do not need to drop frames. Fix the logic in
hideFramesModeSwitch() which currently unconditionally advertises to
drop one frame.
Unfortunately there is no clear way to tell if the sensor is in the HDR
mode. So for now, look the resolution and framerate to deduce this.
Additionally ensure we override hideFramesStartup() and return the same
number as hideFramesModeSwitch().

Split the Raspberry Pi pipeline handler and IPA source code into common
and VC4/BCM2835 specific file structures.
For the pipeline handler, the common code files now live in
src/libcamera/pipeline/rpi/common/
and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/.
For the IPA, the common code files now live in
src/ipa/rpi/{cam_helper,controller}/
and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the
camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/.
To build the pipeline and IPA, the meson configuration options have now
changed from "raspberrypi" to "rpi/vc4":
meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4
