Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.
The change was generated with the following script:
----------------------------------------
dirs="include/libcamera src test utils"
declare -rA patterns=(
['c']=' \* '
['cpp']=' \* '
['h']=' \* '
['py']='# '
['sh']='# '
)
for ext in ${!patterns[@]} ; do
files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done
done
----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

Replace the manual CTRL+Q key sequence with QKeySequence::Quit. This
automatically maps to the native shortcut for the quit action,
regardless of the platform. Even though we don't expect qcam to run on
non-Linux platform, using a QKeySequence is still a good practice when
one exists.
This doesn't change qcam's behaviour, as the native quit key sequence is
CTRL+Q on Linux systems.

When file output is requested from cam app, it simply dumps the
processed data and it must be converted to a readable image format
manually. Let's add support for PPM output file format to make files
produced by cam directly readable by image display and processing
software.
For now, only BGR888 output format, which is the simplest one to use, is
supported but nothing prevents adding support for other output formats
if needed. Nevertheless, they would typically need byte reordering or
other conversions for PPM file format. It may be better to find a way to
dump the image data in other output formats directly using some of the
already existing file formats or raw file format converters.

When a request fails to queue it is completed but with its status set to
RequestCancelled. Add a check in the requestComplete callback to make
sure that the request was completed successfully.
For the SimpleCaptureUnbalanced test we need to do this check only if
the capture isn't over yet, otherwise the few extra requests that get
cancelled at the end, which is the normal behavior, will make the test
fail.

parseRectangles currently always parses Rectangle controls as an array
of Rectangles. This causes non-array Rectangle controls to not be parsed
correctly, as when the ControlValue is get()ed, the non-array assertion
will fail.

has been specified in the yaml capture script to fix that.

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.

When packaging libcamera, distributions may break IPA module signatures
if the packaging process strips binaries. This can be fixed by resigning
the modules, but the process is error-prone.
Add a command line ipa-verify utility that tests the signature on an IPA
module to help packagers. The tool takes a single argument, the path to
an IPA module shared object, and expects the signature file (.sign) to
be in the same directory.
In order to access the public key needed for signature verification, add
a static function to the IPAManager class. As the class is internal to
libcamera, this doesn't affect the public API.

Now that `Camera::generateConfiguration()` takes a `libcamera::Span`
of `StreamRole`, remove the `StreamRoles` type, which was an alias
to `std::vector<libcamera::StreamRole>`.
The removal has two reasons:
- it is no longer strictly necessary,
- its presence may suggest that that is the preferred (or correct)
way to build/pass a list of `StreamRole`.

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.
