Add a libjpeg based JPEG resize tool.
Simple resizer that can resize JPEGs using
"jpgresize input.jpg output.jpg scale_denom(1,2,4,8) quality%".
Tries to use little memory by scanning per line.

Update the workflow in nuttx-apps to match the
corresponding workflow in the main NuttX repository, ensuring
consistency across both CI configurations.
This synchronization follows the guidance from:
https://lupyuen.org/articles/ci3\#sync-to-nuttx-apps
* Aligns CI triggers, job structure, and naming conventions.
* Maintains consistency between NuttX and nuttx-apps CI setups.

Fix invalid preprocessor directive in elf_main.c by changing
`# Warning "No file system selected"` to `# warning "No file system selected"`.
The incorrect uppercase "Warning" directive would cause compilation
errors, while the proper lowercase "warning" directive generates
the intended compiler warning when no file system is selected.

The problem probably arises from an incompatibility issue
between the shv-libs4c and pyshv libraries. The fix is to downgrade
the library for now and then revert back.

The update enables interoperability with a Silicon-Heaven
SHV3 protocol broker implemented in Rust language
https://github.com/silicon-heaven/shvbroker-rs
New commits from shv-libs4c project
https://github.com/silicon-heaven/shv-libs4c
- shv_pack_head_reply: correct reply head for non single element
CID array
When servicing request from the SHV3 protocol version broker
itself then CID array is empty and missing TAG_CALLER_IDS
for empty array breaks encoding scheme.
- shv_process: even in case of unsuccessful attempts to connect
respect request to stop
The request to stop initiate by signal caused the high priority
thread to enter busy-loop and block a system. Check for request
to stop (running flag cleared) even in disconnected state after
unsuccessful attempt.

Fix two error message issues in the framebuffer example:
* Add missing newline character to fbmem2 error message in fb_init_mem2()
* Correct mmap() error message that incorrectly referenced FBIOGET_PLANEINFO
These changes improve error reporting clarity and consistency for debugging framebuffer initialization issues.

Remove the previous guard logic and use a proper CMake
`exclude` rule to prevent `cxx-oot-build` from being
included when building projects with CMake.
* Ensures OOT test project is not pulled into normal apps.
* Keeps CI and export tests isolated from regular builds.

Add the source content for the out-of-tree build test
under `apps/testing/cxx-oot-build`. This supports the
new CI check in NuttX to prevent regressions in the
`make export` workflow.
The test project provides:
* Sample OOT build structure.
* Integration with exported `nuttx-export`.
* Verification of successful build and link.

This commit marks the end of my GSoC 2025 project in the NuttX section.
All changes:
- Silicon Heaven protocol (SHV) implementation:
The library is cloned from github.com/silicon-heaven/shv-libs4c
and compiled here. The library has out-of-the-box support
for NuttX and possibly all posix systems.
The library is compiled with CONFIG_SHV_LIBS4C_PLATFORM define
set to "nuttx". The library's dependancy is Pavel Pisa's ULUT
and originates from Michal Lenc's GSoC.
- examples/shv-nxboot-updater:
An example which constructs a SHV tree with which you can perform
firmware updates using a SHV "file node". The file node wraps
around NXBoot's update partition.
The application also allows for NXBoot confirmation of the images.
This application is to be meant used as a "background service",
started before any apps, possibly using rcS. The tree is allocated
as GAVL (see below).
- examples/shv-test:
An example which constructs a SHV tree and gives the user
the ability to choose which type of construction should be used,
either:
- GAVL: dynamic SHV tree allocation encapsulated within
an AVL tree.
- GSA: dynamic SHV tree allocation encapsulated within
a continuous array with binary search
- GSA_STATIC: SHV tree is defined as static const, this means
all the data structures are placed in .rodata.
Extremely beneficial for embedded systems,
as .rodata is located in flash and embedded
systems usually have more flash than sram,
thus reducing sram usage. The downside is that
the definitions are rather tedious, but can
be automated in case of some code generation
(like in pysimCoder).
All of it is places in a continuous array with
binary search.

This commit implements the loopback mode for the i2schar example
application. This mode - available only when both RX and TX are
enabled - allows the user to test the I2S buses when the TX pin is
connected to the RX pin. This is done by pre-filling a buffer with
known data (additionally, it checks the peripheral's data width to
format the data in the buffer accordingly) and passing it for both
the transmitter and the receiver threads. This buffer is written to
the TX and the received buffer is compared to the known buffer.

Following steps led to incorrect behavior:
- upload update image
- restart device and perform the update
- upload the same update image again without confirming
This led to the unwanted confirm of the update image. This change
ensures the update image is not confirmed by uploading the same
image to the update slot. The correct behavior is to perform revert
to the last stable image if this occurs.
