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.

Previously the code would brighten up images in case the Macbeth Chart
is slightly dark, and also zoom in on sections of it to look for
charts occupying less of the field of view. But it would not do both
together.
This change makes the search for smaller charts also repeat that
search for the brightened up images that it made earlier, thereby
increasing the chances of success for non-optimal tuning images.
There are also a couple of very small drive-by typo fixes.

The build environment may have been incorrect as the problem couldn't be

Starting with meson 0.59, the custom_target() function substitutes
'@BASENAME@' in the output parameter with the input file name, with the
extension removed. This is exactly what we implement manually when
generating the IPA interface .cpp files.
Furthermore, starting with meson 0.60, the 'name' positional parameter
to the custom_target() function is optional, and defaults to the
basename of the output file (including the extension). This is exactly
the name we compute manually and pass to the function.
As libcamera requires meson 0.60 or newer, we can depend on those two
features and drop manual computation of the base name. This fixes a
warning with recent meson versions that complain that passing a file
object to the format() function is a broken feature:

The GStreamer single stream test uses the following pipeline:
libcamerasrc ! videoconvert ! fakesink
The videoconvert element isn't useful as the data is thrown away by the
fakesink anyway. We can shorten the pipeline to
libcamerasrc ! fakesink
to save CPU time and to avoid depending on the gstreamer1.0-plugins-base
package to run the unit tests.
The test could be further simplified by replacing
gst_parse_bin_from_description_full() with gst_element_factory_make(),
now that we only add one element to the bin. The extra cost incurred by
the bin only impacts initialization time, and using a bin will make it
easier to add other elements in the future if needed. Keep the bin, and
only drop the videoconvert element.

Meson uses tags to sort installed files in categories, and makes it
possible to install a subset of the files using the '--tags' argument to
'meson install'. This is typically used by distributions to split the
runtime, development and documentation files into separate packages.
By default, meson tries to guess the correct tag for installed files,
but can't always do so properly. Mark the install targets that meson
can't guess with the correct install_tag.
As the feature has been introduced in meson 0.60, bump the minimum meson
version. The latest LTS release of all major distributions that
libcamera currently targets ship a recent enough meson version.

This commit implements renegotiation of the camera configuration and
source pad caps. A renegotiation can happen when a downstream element
decides to change caps or the pipeline is dynamically changed.
To handle a renegotiation the GST_FLOW_NOT_NEGOTIATED return value has
to be handled in GstLibcameraSrcState::processRequest(). Otherwise the
default would be to print an error and stop streaming.
To archive this in a clean way the if statement is altered into a switch
statement which now also has a case for GST_FLOW_NOT_NEGOTIATED. In the
case of GST_FLOW_NOT_NEGOTIATED every source pad is checked for the
reconfiguration flag with gst_pad_needs_reconfigure() which does not
clear this flag. If at least one pad requested a reconfiguration the
function returns without an error and the renegotiation will happen
later in the running task. If no pad requested a reconfiguration then
the function will return with an error.
In gst_libcamera_src_task_run() the source pads are checked for the
reconfigure flag by calling gst_pad_check_reconfigure() and if one pad
returns true and the caps are not sufficient anymore then the
negotiation is triggered. It is fine to trigger the negotiation after
only a single pad returns true for gst_pad_check_reconfigure() because
the reconfigure flags are cleared in the gst_libcamera_src_negotiate()
function.
If any pad requested a reconfiguration the following will happen:
1. The camera is stopped because changing the configuration may not
happen while running.
2. The completedRequests queue will be cleared by calling
GstLibcameraSrcState::clearRequests() because the completed buffers
have the wrong configuration.
3. The new caps are negotiated by calling gst_libcamera_src_negotiate().
When the negotiation fails streaming will stop.
4. The camera is started again.

We make a few small improvements to the code:
* The arrayToSet method is prevented from overwriting the end of the
array if there are too many values in the input table. If you supply
a table, it will force you to put the correct number of elements in
it.
* The arrayToSet and setStrength member functions are turned into
static functions. (There may be a different public setStrength
member function in future.)
* When no tables at all are given, the configuration is flagged as
being disabled, so that we can avoid copying tables full of zeroes
around. As a consequence, the pipeline handler too will disable this
hardware block rather than run it needlessly. (Note that the tuning
tool will put in a completely empty "rpi.cac" block if no CAC tuning
images are supplied, benefiting from this behaviour.)
* The initialise member function is removed as it does nothing.

The recent change where time-filtering is done before sorting out the
digital gain means that the target exposure without digital gain is no
longer set, breaking the 'AeLocked' calculation.
We can use the regular (full) target exposure instead.

Label draft controls and properties through the "draft" vendor tag
and deprecate the existing "draft: true" mechanism. This uses the new
vendor tags mechanism to place draft controls in the same
libcamera::controls::draft namespace and provide a defined control id
range for these controls. This requires moving all draft controls from
control_ids.yaml to control_ids_draft.yaml.
One breaking change in this commit is that draft control ids also move
to the libcamera::controls::draft namespace from the existing
libcamera::controls namespace. This is desirable to avoid API breakages
when adding new libcamera controls. So, for example, the use of
controls::NOISE_REDUCTION_MODE will need to be replaced with
controls::draft::NOISE_REDUCTION_MODE.
