Introduce a new video device structure representing a device in a
video pipeline. Each video device embeds a pointer to its "source"
device and other "video" characteristics.
This structure give the video framework an access to all video features
of the device and a hierachical view of the video pipeline that the
device belongs to.

file(GENERATE ...) does not update the output file if the content is
unchanged. Since the metadata in build_info.yml mostly depends on the
build configuration, the timestamp of the intermediate file does not get
updated on most rebuilds, while the final file does, due to immediate
file(WRITE ...) calls. Since the latter is newer, no post-process step
is executed and the file is left with commented genexes.
Touching the intermediate file ensures that the post-process step is
performed every time, even if the content is unchanged, restoring the
expected behavior.

Switching the intermediate file format from JSON to YAML has a very
significant benefit: the file is now loaded via yaml_load(), which
internally calls Python to parse the file into the JSON format that
CMake expects. This means that the file contents are now automatically
escaped properly for JSON; it is a huge improvement over the previous
implementation, which was escaping everything given as input to
to_yaml().
With the removal of the now-redundant call in to_yaml(), escaping is
applied exactly once per value or list, when it is passed to yaml_set().
This allows to convert the logic in zephyr_string(ESCAPE ...) to a more
robust "escape everything" approach.
These changes fix the handling of strings with backslashes and different
types of quotes passed either directly or via generator expression. The
existing tests are updated to cover these cases.
Two other small changes are made in this commit:
- a small check in internal_yaml_list_append() is removed, as the same
issue is already detected by the caller yaml_set() logic.
- the to_yaml() function is modified to initialize the YAML output
variable at the top level, which is the expected behavior. This
resulted in genex temp files sometimes having duplicate lines.

The intermediate file used to expand the generator expressions is now in
YAML format. This allows for a more robust handling of the data, as the
single quoted strings are a lot easier to escape: inside them every
character is a literal except for two single quotes (which intuitively
map to a literal single quote).
When saving a simple YAML file without genexes, the single quotes in
strings need to be escaped. However, doing so when saving the
intermediate file would make it harder to properly escape them later,
since it could be possible that the expansion of the generator
expressions would introduce new single quotes. For this reason, when
genexes are enabled, the escaping is now done in a single pass inside
the yaml-filter.cmake script.

Store strings in YAML as single-quoted entries to avoid issues with

MCUboot has a configuration for single application slot RAM loading, in
which the single loader (or a hook thereof) can load an application from
an arbitrary flash location to RAM. Applications that are to be loaded
in this way need to specify, in their mcuboot header, the load address
in RAM they are meant to be loaded.
This patch adds a new Kconfig for this mode. The load address used comes
from devicetree chosen property "mcuboot,ram-load-dev", if it exists,
and if not, "zephyr,sram".

MODULE_EXT_ROOT allows Zephyr modules to provide glue code for Zephyr
modules using `cmake-ext: True` and/or `kconfig-ext:True`.
A module ext root provides a `modules.cmake` file which defines
variables like: `set(ZEPHYR_FOO_CMAKE_DIR <glue-code-path>/foo)`
It is intended that a downstream module can replace Zephyr's default
glue code, which again can be replaced further downstream.
Setting values in first modules.cmake (Zephyr's) are replaced by later
processed modules.cmake (downstream) when the setting name is identical.
Therefore the module ext root list should not be reversed, and Zephyr
itself should be placed as first entry in the list.

As of c952f09a79 the calls to west
sign were replaced with imgtool but a lingering integration with
WEST_TOPDIR was allowed to remain which is not needed when there
are absolute paths available for the configuration. So, this
attempts to refactor the code to allow a few things
- allow a search of relative paths to application config and
then west topdir
- only fatal error when a west workspace is needed but not found,
so if the config is all absolute files then a west workspace is
not required

All in all this makes cmake linker generator able to work for at least
most of the kernel tests and samples, on cortex m4.
Make the cmake linker generator have a file-structure more similar to
the ld-skeletons.
Add or edit groups, sections and logic to make the generator reflect
what the ld-skeletons do, esp. for kobjects and APP_SMEM, nonint and
some other details are also effected.
Use the new zephyr_linker_include_generated() and
zephyr_linker_include_var() functions to to handle
${DEVICE_API_LINKER_SECTIONS_CMAKE}, the kobject-prebuilt-*.h files and
APP_SMEM partition. Essentially the output from gen_app_partitions.py,
gen_kobject_placeholders.py.
Add ALIGN_WITH_INPUT on sections being put into DATA_REGION. This makes
the init layout work for ld.
This leverages the updates in gen_app_partitions.py to generate its

Add methods for the linker-script generator to pick up information
from previus linkerpasses:
* zephyr_linker_include_generated(FILE f.cmake [PASS X] [KCONFIG])
cmake-includes f.cmake in the relevant PASSes. This allows scripts
to generate any content (e.g. sections or section configs) as if
it was generated by the main cmake machiery. This is intended to
cover the case of ld-script snippets generated by e.g.
gen_app_partitions.py
It can also parse KCconfig files to capture @CONFIG_FOO@ variables
* @FOO[,undef:v]@ in an value or expression in the zephyr_linker_*
inputs. This looks for a defintion of FOO (se below), and uses its
value if found. If FOO is not defined, the whole @@ thing is left
untouched, unless ,undef: is used, in which case v is used instead.
* zephyr_linker_include_generated(FILE f.h [PASS x]) greps for f.h
for #define FOO value to be accessed as @FOO@
* zephyr_linker_include_var(VAR FOO VALUE V) allows the main
cmake-script to set a @FOO@ variable.
Note that the #define support is VERY basic, and does not use a proper
pre-processor. It works for the current use of files generated by e.g.
gen_kobject_placeholders.py but is not a general solution.

Recently 0ae0c3dc44 allowed for three digit priorities, this resulted
in objects potentially matching multiple sections, for example:

.z_init_PRE_KERNEL_2_?_*
.z_init_PRE_KERNEL_2_???_*

unambiguous, this has the extra value of making it easier to interpret,
