Add a minimal VNC viewer application that connects to a VNC server
and renders the remote desktop on a local LCD.
Features:
- RFB 3.8 protocol with VNC Authentication (DES, pure software)
- Raw encoding with pixel format auto-detected from LCD driver
- Row-by-row rendering via LCDDEVIO_PUTAREA (minimal RAM usage)
- LCD resolution and format queried at runtime via LCDDEVIO_GETVIDEOINFO
- Auto-reconnect on connection loss with 2-second retry
Usage:
vncviewer <host> [port]
vncviewer -p <password> <host> [port]
vncviewer -p <password> -d <lcd_devno> <host> [port]

The upper-half RMT driver is no longer available on NuttX. Instead,
Espressif's RMT peripheral was bound directly to the lirc driver.
For testing purposes, use the `irtest` application. NuttX OS PR
https://github.com/apache/nuttx/pull/18654 removed the upper-half
driver interface used by this application, so removing it does not
break any existing feature on NuttX.

Value zero in tm_isdst means daylight saving time (or summer
time) is not in effect. This is obviously not true for half of the year
in most timezones and keeping it at zero leads to incorrect time
being set. This commit sets tm_isdst to -1, which means the information
is not available and it should be handled according to timezone rules.

Add -m command line option to enable horizontal mirror on the
camera sensor via VIDIOC_S_CTRL + V4L2_CID_HFLIP. This uses
the sensor hardware mirror (e.g. GC0308 register 0x14 bit[0])
with zero CPU overhead.
Also refactor parse_arguments to use a loop-based parser so
options can appear in any order.
Usage: camera 0 -m (mirror preview)
camera -jpg -m (mirror still capture)

Some image sensors on 8-bit DVP buses (e.g. GC0308) produce RGB565X
(big-endian) pixel data — the high byte is clocked out first and
stored first in PSRAM by the ESP32-S3 CAM controller.
The V4L2 framework does not negotiate formats automatically, so try
RGB565 first and fall back to RGB565X if S_FMT fails.
When the sensor reports RGB565X:
- Invalidate D-Cache after DQBUF so the CPU reads fresh DMA data
- Byte-swap each pixel in place from BE to LE RGB565 for display

Use MMAP buffer allocation by default so the driver can manage
DMA-capable memory with proper alignment and cache attributes.
Fall back to USERPTR if the driver does not support MMAP.
Also fix NX framebuffer stride calculation to use the actual
display width instead of hardcoded values.

The patch step currently uses a phony target, so it is executed
again when the build is repeated in the same source tree. In that
case `patch -N` detects previously applied patches and returns 1,
which make treats as a failure.
Replace the phony patch target with a stamped `.patched` file so
the patch step is not re-run unnecessarily.

This is necessary because new defconfig were recently added to
Xtensa-based Espressif SoCs and the build job may exceed 2 hours.
In order to avoid increasing job timeout, a specific job for each
supported SoC (ESP32, ESP32-S2 and ESP32-S3) was created instead.

When a command has no arguments (e.g., 'q', 'quit', 'stop'), the strtok_r()
function returns NULL for the arg parameter. The argument trimming loop was
dereferencing this NULL pointer without checking, causing undefined behavior
and system hang on ESP32-S3.
This commit adds a null check before dereferencing the arg pointer in the
leading space trimming loop.
Tested on ESP32-S3 (lckfb-szpi-esp32s3) - quit command now works correctly.

SOCK_CLOEXEC and SOCK_NONBLOCK were incorrectly passed as the
third argument (protocol) instead of being OR'd into the second
argument (type). This caused socket() to fail with EPROTONOSUPPORT
(errno 93) on NuttX.

protocol to 0.

Two hardening fixes for nxboot power-loss resilience:
1. Add flash_partition_flush() calls between critical partition
operations in perform_update(). Without explicit flush barriers,
writes may remain buffered in RAM (e.g. via FTL rwbuffer) when
nxboot proceeds to the next phase. A power loss between phases
can leave the recovery image uncommitted while the staging
partition has already been consumed.
Flush points added:
- After copy_partition(primary, recovery) completes
- After copy_partition(update, primary) completes, before
erasing the staging first sector
2. Replace validate_image_header() with validate_image() in the
final primary validation path of nxboot_perform_update(). The
header-only check validates magic and platform identifier but
does not CRC-check the image body. After an interrupted update,
a corrupt primary with an intact header would pass this check
and be booted, resulting in a persistent boot failure.

X86 support for Rust needs more test and verification, and not
upstreamed to Rust side yet.
It's better to use custom target triples for x86 by json files for now,
and it can be upstreamed to Rust side if stable enough.
Changed the Rust target triples in the CMake configuration to reference JSON files for x86_64 and i486 architectures. This improves the build process by providing more detailed target specifications.
* Added JSON files for i486 and x86_64 targets
* Updated CMake functions to use the new target triples
* Enhanced build directory structure for Rust crates
