Look for the RAW mandatory stream flag in the pipeline handler config
file. If this flag is set, it guarantees that the application will
provide buffers for Unicam Image, so override the minUnicamBuffers and
minTotalUnicamBuffers config parameters in the following way:
- If startup drop frames are required, allocate at least 1 internal buffer.
- If no startup drop frames are required, do not allocate any internal buffers.
Look for the Output 0 mandatory stream flag in in the pipeline handler
config file. If this flag is set, it guarantees that the application
will provide buffers for the ISP, do not allocate any internal buffers
for the device.
Add a new rpi_apps.yaml pipeline handler config file that enables both
these flags. To use the file, set the following env variable for a
custom build:
export LIBCAMERA_RPI_CONFIG_FILE=/usr/local/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml
or for a packaged install:
export LIBCAMERA_RPI_CONFIG_FILE=/usr/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml

Add support for the following HDR modes in the Raspberry Pi IPA:
- Night mode
- Single exposure mode
- Multi-exposure (merged and unmerged)
The algorithm is updated to expect the HDR short channel to meter
explicitly for highlights. This means that it will not in general
under-expose the short channel more than is actually necessary.
When images don't have much saturation, it's good to detect this so
that some of the boost we want to apply to the dark areas can be
implemented as regular gain. This means we can then adjust the tone
curve less, leading to less flat looking images.
The impact on the HDR algorithm is then that this determines how we
build tonemaps dynamically. The highlights are more-or-less correct
now, so we have to build a power-type curve that gives us the
appropriately configured targets in the lower part of the histogram.
We allow the tuning file to supply the maximum spatial gain value,
rather than the whole curve (though it can supply this if it
wants). Some parameter defaults are tweaked to be generally better
across the range of our cameras.

If no ISP output streams are configured, the ISP output count is skipped
for the the low res stream, and causes the drop frame logic to fail
because of a count mismatch. This in-turn stops any requests from
completing correctly.
Fix this by ensuring the low res output is counted correctly when no ISP
output streams are configured.

We add an HdrMode control (to enable and disable HDR processing)
and an HdrChannel, which indicates what kind of HDR frame (short, long
or medium) has just arrived.
Currently the HdrMode supports the following values:
* Off - no HDR processing at all.
* MultiExposureUnmerged - frames at multiple different exposures are
produced, but not merged together. They are returned "as is".
* MultiExposure - frames at multiple different exposures are merged
to create HDR images.
* SingleExposure - multiple frames all at the same exposure are
merged to create HDR images.
* Night - multiple frames will be combined to create "night mode"
images.

AWB writes this out during prepare, so we may as well read it in AGC
prepare as well. Reading it in process is wrong on the PiSP platform
because process runs before prepare, so the AWB status won't be there

The current definition of operator*(Transform t1, Transform t0) follows
the function composition notion, where t0 is applied first then t1 is
applied last.
In order to introduce operator*(Orientation, Transform) where a
Transform is applied on top of an Orientation, invert the operand order
of operator*(Transform, Transform) so that usage of operator* with both
Orientation and Transform can be made associative.
For example:
Orientation o;
Transform t = t1 * t2
Orientation o1 = o * t
= o * (t1 * t2) = (o * t1) * t2 = o * t1 * t2

If the pipeline runs out of embedded data buffers, then it will pass
the frame to the IPA without the metadata. The IPA then has to use the
delayed controls as inputs to the algorithms. This can cause problems
with the subsequent algorithms if the sensor did not action the
controls, especially with the autofocus as that doesn't have controls
which can be passed in lieu of the metadata.
Reduce the likelihood of this by increasing the number of embedded data
buffers, as they are small so a generous number can be allocated.
