Object instances are meant to be deleted from the thread they are bound
to, and this requirement is documented. There are however exceptions to
the rule, as threads may be stopped and restarted, with objects bound to
them not being deleted and recreated for every stop/restart cycle. Bound
objects may therefore need to be deleted after the thread has stopped,
making it impossible to use Object::deleteLater().
Document the lifetime requirements more precisely, and enforce them with
an assertion.

The TimeoutHandler used in the test is destroyed from the main thread,
which is invalid for a thread-bound object bound to a different thread.

Starting a timer from the wrong thread is expected to fail, and we test
this in the timer-thread unit test. This is however not something that a
caller is allowed to do, and libcamera will get assertion failures to
catch this invalid usage. The unit test will then fail.
To prepare for this, split the unit test in two, with a test that is
expected by meson to succeed, and one that is expected to fail. The
assertion will then cause an expected failure, making the test suite
succeed.

The slow receiver test verifies there's no race condition between
concurrent message delivery and object deletion. This is not a valid use
case in the first place, as objects are not allowed to be deleted from a
different thread than the one they are bound to. Remove the incorrect
test.

Objects can be scheduled for deletion with Object::deleteLater(), which
queues a deferred deletion to the thread's event loop. As the
deleteLater() function is meant to be called from a different thread,
this may race with thread termination, and deferred deletions queued
just before calling Thread::exit() may not be processed by the event
loop. Make sure they get processed when finishing the thread, before
stopping.
This eliminates the race condition that occurs when calling
Object::deleteLater() followed by Thread::exit() from the same thread.
Calling deleteLater() from neither the thread the object is bound to or
the thread calling Thread::exit() is still inherently racy.
The change fixes a failure in the object-delete unit test.

The signal.h header doesn't need to include object.h. Replace it with a
forward declaration, and instead include object.h in source files that
require it. It can speed up compilation a little bit, but more
importantly avoids unintended dependencies from the Signal class to the
Object class to be added later as the compiler will catch them.

The attributes checker ensures that .mojom files don't contain unknown
attributes. These check fail with the custom 'skipSerdes' and 'async'
libcamera attributes. Ideally the list of supported attributes should be
extended, but that can't easily be done without modifying the mojo
sources that we try to keep identical to the upstream version to make
updates easier. Disable the attributes checker completely for now to fix
this issue.
While at it, fix an indentation issue reported by checkstyle.py.

The update-mojo.sh script starts by removing all sources before copying
the new files from chromium. A bug in the 'rm' command makes the removal
a no-op: the glob pattern is quoted, which attempts to remove a file
name '*' in the tools directory, not all files in the directory. Fix it
by removing the whole utils/ipc/mojo/ directory.
While at it, also remove the utils/ipc/tools/ directory that contains
imported sources.

The pre-push hook validates the commit messages utilising 'echo' to send
the captured data from the git commit through grep.
Commit messages may occasionally contain strings that could appear to be
escape sequences such as doxygen style references to \struct.
The '\' 'c' escape sequence can be interpreted to supress all further
output [0] which then breaks the processing and string matching.
Unfortunatley for us, doxygen's class reference constructed in the same
form as \struct can be interpreted as the escape sequence to supress
further output.
[0] https://www.gnu.org/software/bash/manual/bash.html#Bash-Builtins
Update the pre-push hook to explicitly disable escape sequence
interpretation using the '-E' flag. This is not available on the
posix-compliant shell 'dash', so also switch to bash explicitly to
prevent potential failures.

All the Raspberry Pi official camera tuning files are updated for
HDR. As stated previously, there is no mechanism in the hardware for
combining images so all this does is enable multi-channel AGC to
produce short and long exposure frames. It will be up to the
application to deal with them.
The changes are identical in every tuning file.
1. The existing AGC tuning is duplicated twice so that we have 3 AGC
channels.
2. The first is left alone (the default AGC channel), the second is
tweaked to under-expose significantly (ev -3) and the final one is
tweaked to over-exposure slightly (ev +0.5)
3. Control parameters are provided to the "rpi.hdr" algorithm to
associate these AGC channels correctly with the HDR modes.

Sufficient plumbing is added so that the HDR mode control can be used
to engage HDR modes on platforms that support them. On the vc4
platform, this allows multi-channel AGC to run, though there is no
image merging.

The vector in question is destroyed when the item in the `buffers_` map
is destroyed as a result of the `erase()` call. A vector's destructor
already does all the things that `clear()` does,
so calling it earlier is not needed.

The IPADataSerializer::deserializer attempts to optimise code paths and
remove potentially unused code where multiple File Descriptors were not
expected to be utilised.
The addition of multiple SharedFD entries in the IPC highlights this as
a bug.
Clean up the conditionals to ensure that all File Descriptors are
correctly deserialized.

this outputs the ISP statistics as a uint8_t span through the Bcm2835StatsOutput

to a protected member variable. This makes it accessable to the VC4
