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]

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.
Move SOCK_CLOEXEC | SOCK_NONBLOCK to the type parameter and set
protocol to 0.

This patch adds support for dumping binary contents from noteram via the
`trace dump -b <file>` command. Changes include:
- Add a `binary` parameter to `trace_dump()` and the public header
`system/trace/trace.h` to indicate binary output mode.
- Update `trace_dump()` to set the noteram read mode to binary using
`NOTERAM_SETREADMODE` when requested.
- Update `trace dump` CLI parsing in `system/trace/trace.c` to accept
the `-b` flag and pass it through to `trace_dump()`.
- Update usage/help text to include the new `-b` option.

The sigint() function uses siginfo->si_user but was declared with
only one parameter (int sig). This causes compilation error because
siginfo is undeclared.
Fix by:
1. Rename sigint to cu_exit with proper sigaction signature
2. Use sa_sigaction instead of sa_handler to receive siginfo_t
3. Pass cu pointer via sa.sa_user for signal handler access

the kernel can only prevent the concurrency of s/getsockopt, but
iptables will call these interfaces multiple times at a time. We
need to wait for one iptables to complete before executing the second
one, otherwise the data will be overwritten.
iptables flow:
get current iptables entries [1] -> add new entry 2 [1,2] -> set to kernel [1,2]
get current iptables entries [1] -> add new entry 3 [1,3] -> set to kernel [1,3]
entry 2 is lost

Due to DMA-based transfers, the rx buffer can receive a large amount
of data at once. The previous character-by-character processing approach
was inefficient.
Modify character-by-character read to block read of the entire buffer.
This improves throughput and reduces CPU overhead, especially for high-speed
serial communication or other DMA-based transfers.
