The 16-bit padded raw 10 and raw 12 formats are stored in memory in
little endian order, regardless of the machine's endianness. Read pixel
data as uint8_t values and hardcode bit shifting to little endian to fix
scanline packing.

The 16-bit padded raw 10 and raw 12 formats are stored in memory in
little endian order, regardless of the machine's endianness. Swap the
16-bit values on big-endian machines when reading pixels from memory to
generate thumbnails.

Add support for RAW10 and RAW12 to the dng_writer. This is needed on
imx8mp to produce tuning images. Both formats were tested on a debix
som with a imx335.

Add a thumbnail function for raw formats that are 16bit aligned.
This is needed for the upcoming RAW10 and RAW12 implemntation.
Use the new function for RAW16 as the thumbScanlineRaw_CSI2P produces
incorrect results for that format (it averages over adjacent bytes,
which works for the CSI formats).

In libtiff version 4.5.1 and later the CFA* tags were missing. This got
fixed in https://gitlab.com/libtiff/libtiff/-/commit/49856998c3d82e65444b47bb4fb11b7830a0c2be
Unfortunately the fix is not released yet, but the faulty libtiff is
contained in current buildroot. As a local fix is pretty easy and
without side effects, let's workaround that.

Multiple local functions are defined in the global namespace without the
static keyword. This compiles fine for now, but will cause a missing
declaration warning when we enable them. To prepare for that, move the
function declaration to an anonymous namespace.
While at it, for consistency, include an existing static function in the
namespace and drop the static keyword.

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.

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.

Clearly all cases in the switch are already satisfied, but some

Add a default case for the switch-case on a modulo to silence this.

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`.

Multiple source files in the src/apps/cam/ directory are used by cam,
qcam and lc-compliance. They are compiled separately for each
application. Move them to a new src/apps/common/ directory and compile
them in a static library to decrease the number of compilation
operations.
