checkstyle.py uses single-quoted strings in most locations already.
There are a few locations where this wouldn't be convenient (when the
string itself contains a single quote, which would then require
escaping), but there are also a few other locations where double quotes
are used when single quotes would work fine. Change those to standardize
on single-quoted strings.

The LIBCAMERA_O_PTR() define adds the ';' at the end of the
templated call to _o().
While this works for the only current user in camera_manager.cpp, even
the statement there adds another semi-colon following it.

The documentation suggests to use CameraConfiguration::operator[] to
access the StreamConfiguration it contains, but as CameraConfiguration
instances are generated by the Camera class and are returned wrapped in
a unique_ptr<>, the usage of operator[] would require an awkward syntax such
as (*config)[i].
Better to suggest the usage of the CameraConfiguration::at() function
instead to access the StreamConfigurations.

Pipeline managers sets a default value to StreamConfiguration::size. The
original fixation code was attempting to use it, but as it was truncating
the caps to its first structure it would never actually find a best match.
In this patch, instead of truncating, we weight various matches using the
product of the width and height delta. We also split delta from ranges
apart and prefer fixed size over them as ranges are not reliable.
This patch also removes the related todo, as it seems that libcamera core
won't go further then providing this default value and won't be sorting the
format and size lists.

It's not allowed in GStreamer to push events while holding the object
lock. This reduce the scope into which we hold the object lock. In
fact we don't need to protect against gst_task_resume() concurrency

ASan needs to be loaded first before gstreamer is loaded. This was not
possible, so verify_asan_link_order was disabled. Better way to tackle
this issue was disabling forks on the gstreamer side.
verify_asan_link_order=0 disables the check on ASan side which checks if
ASan was loaded before any other shared objects. Since, gstreamer spawns
a child helper process while building the registry, we needed to disable
this check. But with gst_registry_fork_set_enabled() it is possible to
disable spawning this child helper process, so this ensures that ASan is
loaded before any other shared object is loaded.

Introduce a new algorithm to manage the tone mapping handling of the
IPU3.
The initial algorithm is chosen to configure the gamma contrast curve
which moves the implementation out of AWB for simplicity. As it is
initialised with a default gamma value of 1.1, there is no need to use
the default table at initialisation anymore.
This demonstrates the way to use process() call when the EventStatReady
comes in. The function calculates the LUT in the context of a frame, and
when prepare() is called, the parameters are filled with the updated
values.
AGC is modified to take the new process interface into account.

Introduce three functions in the Algorithm class to manage algorithms:
- configure which is called when IPA is configured only
- prepare called on EventFillParams event at each frame when the request
is queued
- process called on EventStatReady event at each frame completion when
the statistics have been generated.
The existing AGC implementation already has a function named process(),
though it has different arguments. Adding the new virtual process()
interface causes a compiler warning due to the AGC implementation
overloading a virtual function, even though the overload can be resolved
correctly.
Temporarily disable the warning in this commit to maintain bisection
until the AGC is converted to the new interface.

IPU3.
Not documenting the namespace may cause issues with Doxygen in libipa.

IPCMessage::payload() converts the IPCMessage into an IPCUnixSocket
payload. However, if IPCMessage is constructed with one of the
following constructors -
IPCMessage::IPCMessage(),
IPCMessage::IPCMessage(uint32_t cmd)
IPCMessage::IPCMessage(const Header &header)
The data_ vector of IPCMessage is empty and uninitialised. In that
case, IPCMessage::payload will try to memcpy() an empty data_ vector
which can lead to invoking memcpy() with a nullptr parameter, which
is then identified by the address sanity checker.. Add a non-empty
data_ vector check to avoid it.
The issue is noticed by running a test manually, testing the vimc
IPA code paths in isolated mode. It is only noticed when the test
is compiled with -Db_sanitize=address,undefined meson built-in option.

Regarding (de)serialization in isolated IPA calls, we have four layers:
- struct
- byte vector + fd vector
- IPCMessage
- IPC payload
The proxy handles the upper three layers (with help from the
IPADataSerializer), and passes an IPCMessage to the IPC mechanism
(implemented as an IPCPipe), which sends an IPC payload to its worker
counterpart.
When a FileDescriptor is involved, previously it was only a
FileDescriptor in the first layer; in the lower three it was an int. To
reduce the risk of potential fd leaks in the future, keep the
FileDescriptor as-is throughout the upper three layers. Only the IPC
mechanism will deal with ints, if it so wishes, when it does the actual
IPC. IPCPipeUnixSocket does deal with ints for sending fds, so the
conversion between IPCMessage and IPCUnixSocket::Payload converts
between FileDescriptor and int.
Additionally, change the data portion of the serialized form of
FileDescriptor to a 32-bit unsigned integer, for alightnment purposes
and in preparation for conversion to an index into the fd array.
Also update the deserializer of FrameBuffer::Plane accordingly.

Development and usage of isolated IPA's has identified bugs in the
transmission of the file descriptors between the pipeline handler and
the IPA through.
Add tests to identify these bugs and prevent regressions.
This tests basically checks for two things:
- Camera reconfigurations without stopping CameraManager
- Fd leaks across IPA IPC boundary [1]
Currently, it uses vimc, but can be easily changed to using another
platform (for e.g. IPU3) by changing kCamId_ and kIpaProxyName_.
The test performs kNumOfReconfigures_ (currently set to 10)
reconfigurations of the camera. Each reconfiguration runs
start(), capture(100ms), stop() of the camera. Hence, the test
runs approximately for 1 second.
For checking the fd leaks, the test monitors the /proc/$PROXY_PID/fd
directory for open fds. It compares the number of open fds after each
run to the number of open fds before the first run. If those two are
found to be mis-matched, the test shall report failure.
The test validates IPA IPC code paths which are used when the IPA is run
in isolated mode. The CameraTest is constructed with the isolate flag
set to enforce this.
