Support for the OmniVision OV8858 sensor is scheduled for inclusion in
the Linux kernel in version v6.3.
Add support for the sensor in libcamera by providing static properties
and a camera sensor helper in libipa.
The camera sensor helper expresses analogue gain increments in 1/128
step which differs from what is reported in the sensor documentation in
section "5.8 manual exposure compensation/ manual gain compensation" [0]
A more detailed analysis of the sensor gain model is reported at:
2022110617.166892-2-nicholas@rothemail.net/#142267
Record with a \todo note a reference to discussion on the gain model
implementation.

When an IPA module is loaded, the loadIPAModuleInfo() function validates
the ipaModuleInfo structure. As part of that process, it checks that the
ipaModuleInfo symbol size matches the expected structure size. This
check breaks with clang and ASan, as the LLVM's address sanitizer
implementation includes the redzone after the structure in the symbol
size, currently growing it by 156 bytes (on x86-64). This causes all IPA
modules to fail to load.
Fix the problem by relaxing the size check to only ensure that the
symbol is large enough to contain the structure.

Not all C libraries include support for locale objects (locale_t) and
the strto*_l() family of functions. A notable example is uClibc that can
be compiled with a hardcoded "C" locale. Compilation then fails as the
newlocale(), freelocale() and strtod_l() functions are not defined.
Fix the compilation breakage by checking for the availability of the
locale_t type, and fall back to strtod() when the type isn't available.
This may not lead to the correct result if support for locale objects
isn't available and the locale isn't hardcoded to "C", but that is such
a corner case that we will likely never encounter it.

strtod_l() to fix that issue, but that function is not available with

out of scope for the YamlObject class.
As a first step, add a strtod() helper function in the utils namespace

When parsing configuration files on systems with differing locales, the
use of strtod can produce different results, or in the worst case - fail

Fix this by using strtod_l() instead. To avoid constructing and
destructing a locale_t instance for every use of strtod_l(), create an
RAII class that wraps the locale_t and use it to provide a global "C"
locale.

In the simple capture tests, in the capture functions, the Requests were
auto-deallocated by the function going out of scope after the test
completed. However, before the end of the scope, the Framebuffers that
the Requests referred to were manually freed. Thus when the Requests
were deallocated, they tried to cancel their Framebuffers, which involve
setting the status to cancelled, which obviously causes a segfault
because the Framebuffers had already been freed.
Fix this by moving the list of Requests to a member variable and
deallocating them before deallocating the Framebuffers at stop() time.

The digital gain calculation uses a total exposure value computed with the
current AGC state. However, this is wrong in the case of manual shutter/gain
controls, as the total exposure value used must be the value computed when the
AGC sent the manual shutter/gain controls to the pipeline handler to action.
To fix this, the IPA now adds the historical AgcStatus structure to the metadata
(tagged with "agc.delayed_status"). This historical AgcStatus structure contains
the total exposure value calculated when the AGC sent the manual shutter/gain
controls to the pipeline handler.

per prepare()/process() invocation, when running the controller algorithms. This
allows historical metadata objects to be retained, and subsequently passed into
the controller algorithms on future frames. At present, only a single index into
this array is used.
This change provides a route to fixing a problem with the AGC algorithm, where
if a manual shutter/gain is requested, the algorithm does not currently retain
any context of the total exposure that it has calculated. As a result, the
wrong digital gain would be applied when the frame with the manual shutter/gain

- The params and stats buffers don't need to be allocated, and the
corresponding video nodes don't need to be started or stopped.
- The IPA module fillParamsBuffer() operation must not be called in
queueRequestDevice(). As a result, the IPA module thus doesn't emit

- The tryCompleteRequest() function must not to wait until the params
