626172a16b libcamera: Drop file name from header comment blocks
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.

fd98779d78 libcamera: transform: Make the transformFromOrientation() function static
Now that the transformFromOrientation() function isn't used outside of
transform.cpp, make it static to remove it from the public API.

53b4419986 libcamera: transform: Fold transformToOrientation() in its only caller
The transformToOrientation() function is called from

Orientation operator*(const Orientation &o, const Transform &t);

only. Fold the code in the caller and drop the transformToOrientation()
function to drop what can be considered as an ill-defined operation from
the API.

8bb0f472c3 libcamera: transform: Add operations with Orientation
Add two operations that allows to combine Transform with Orientation.

- Transform operator/(const Orientation &o1, const Orientation &o2)
  allows to easily get back the Transform that needs to be applied to
  Orientation2 to get Orientation1

- Orientation operator*(const Orientation &o, const Transform &t)
  allows to apply a Transform to an Orientation and obtain the
  combination of the two

These two operations allow applications to use Transforms to
manipulate the Orientation inside the CameraConfiguration, if they
wish.

0a64cf8b76 libcamera: Convert to pragma once
Remove the verbose #ifndef/#define/#endif pattern for maintaining
header idempotency, and replace it with a simple #pragma once.

This simplifies the headers, and prevents redundant changes when
header files get moved.

edf19e4c72 libcamera: Add Transform enum to represent 2D plane transforms.
We implement 2D transforms as an enum class with 8 elements,
consisting of the usual 2D plane transformations (flips, rotations
etc.).

The transform is made up of 3 bits, indicating whether the transform
includes: a transpose, a horizontal flip (mirror) and a vertical flip.
