Currently, the stream configuration is stored in two vectors, rawStreams
and outStreams for convenience. However, these vectors are constructed
in both platformValidate() and platformConfigure().
This change caches these vectors in the RPiCameraConfiguration class to
construct them only once in platformValidate().
Pass a pointer to the current configuration to platformValidate() and
platformConfigure() so that they can access the streams vectors.

Handle the SensorConfiguration provided by the application in the
pipeline validate() and configure() call chains.
During validation, first make sure SensorConfiguration is valid, then
handle it to compute the sensor format.
For the VC4 platform where the RAW stream follows the sensor's

The IPA stores a list of the last 10 frame lengths applied to the
sensor for determining the timeout to use. This list gets reset on
start(), but there is a path through the code that accesses this list
in configure() which happens earlier, causing a logical error.
Fix this by constructing the list with 10 initial values of 0s.

The frame counter test to determine if we run the IPA algorithms has a
logic bug where it treats dropFrameCount_ and mistrustCount_ as frame
numbers, not counts of frames (which it is). The implication is that
startup convergence and initial settings take one extra frame to apply.

The Android CameraDevice class adds a sourceStream for each Mapped
stream requested by the framework.
When mapping multiple framework streams to the same sourceStream, the
implementation of CameraDevice::processCaptureRequest wrongly erases the
just added sourceStream from the list of streams to request to
libcamera.
Fix this by adding the stream instead of erasing it.

A channel constraint is somewhat similar to the upper/lower bound
constraints that we use elsewhere, but these constraints apply between
multiple AGC channels. For example, it lets you say things like "don't
let the channel 1 total exposure be more than 8x that of channel 0",
and so on. By using both an upper and lower bound constraint, you
could fix one AGC channel always to be a fixed ratio of another.
Also read a vector of them (if present) when loading the tuning file.

The switchMode, prepare and process methods are updated to implement
multi-channel AGC correctly:
* switchMode now invokes switchMode on all the channels (whether
active or not).
* prepare must find what channel the current frame is, and run on
behalf of that channel.
* process updates the most recent DeviceStatus and statistics for the
channel of the frame that has just arrived, but generates updated
values working through the active channels in round-robin fashion.
One minor detail in process is that we don't want to change the
DeviceStatus metadata of the current frame, so we now pass this to the
AgcChannel's process method, rather than letting it find the
DeviceStatus in the metadata.

This commit does the basic reorganisation of the code in order to
implement multi-channel AGC. The main changes are:
* The previous Agc class (in agc.cpp) has become the AgcChannel class
in (agc_channel.cpp).
* A new Agc class is introduced which is a wrapper round a number of
AgcChannels.
* The basic plumbing from ipa_base.cpp to Agc is updated to include a
channel number. All the existing controls are hardwired to talk
directly to channel 0.
There are a couple of limitations which we expect to apply to
multi-channel AGC. We're not allowing different frame durations to be
applied to the channels, nor are we allowing separate metering
modes. To be fair, supporting these things is not impossible, but
there are reasons why it may be tricky so they remain "TBD" for now.
This patch only includes the basic reorganisation and plumbing. It
does not yet update the important methods (switchMode, prepare and
process) to implement multi-channel AGC properly. This will appear in
a subsequent commit. For now, these functions are hard-coded just to
use channel 0, thereby preserving the existing behaviour.

The Agc::process() function returns an AgcStatus object in the
metadata as before, but Agc::prepare() is changed to return the values
it computes in a separate AgcPrepareStatus object (under the new tag
"agc.prepare_status").
The "digitalGain" and "locked" fields are moved from AgcStatus to
AgcPrepareStatus.

order in which prepare() and process() are called, without them

Handling ioctl's within applications is often wrapped with a helper such
as xioctl. Unfortunately, there are many instances of xioctl which
incorrectly handle the correct size of the ioctl request.
This leads to incorrect sign-extension of ioctl's which have bit-31 set,
and can cause values to be passed into the libcamera's v4l2 adaptation
layer which no longer represent the true IOCTL code.
Match the implementation of the Linux kernel and ensure that only 32
bits of the ioctl request are used by assigning to an unsigned int.

New TI SoCs from J7 and AM62 family have a camera pipeline that receives
data using Cadence's DPHY-RX and CSI-RX bridge. A pixel-grabbing "shim"
IP routes this incoming stream of data to the DMA subsystem, to finally
store the frame data in memory.
The driver for this is not merged in mainline yet, but v7 was posted [1]
on linux-media list a few months ago.
With some minor fixes, the work-in-progress v8 series [2] works with the
simple pipeline handler, so we enable support for this device.

Change the parameter type of `generateConfiguration()` from `const std::vector&`
to `libcamera::Span`. A span is almost always preferable to a const vector ref
because it does not force dynamic allocation when none are needed, and it allows
any contiguous container to be used.
A new overload is added that accepts an initializer list so that
cam->generateConfiguration({ ... })
keeps working.
There is no API break since a span can be constructed from a vector
and the initializer list overload takes care of the initializer lists,
but this change causes an ABI break.
