This commit adds CMUX (GSM 07.10) protocol support to netutils.
CMUX allows multiplexing multiple virtual serial connections
over a single physical serial link.
Changes include:
- CMUX protocol implementation
- CRC table for frame validation
- Basic frame handling

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.

Add support for Xedge, an embedded software toolkit for IoT applications
using Lua scripting with HTTP(S), WebSockets, MQTT, and device I/O.
* netutils/xedge: Dependency manager that downloads BAS library
and BAS-Resources, generates XedgeZip.c during build
* examples/xedge_demo: Complete example showing Xedge integration
with HTTP server, Lua runtime, and SNTP time synchronization

Currently NANOPB_UNPACK step in Makefile uses nanopb binary name with
hardcoded suffix '-linux-x86' that is not suitable for MACOS x86.
This commit replaces the hardcoded nanopb binary name with name that
is derived from NANOPB_NAME variable that reflects the nanopb binary
that is selected based on host OS selected in the build system

remove empty strings from FetchContent to eliminate cmake build warnings like this:
CMake Warning (dev) at /usr/share/cmake/Modules/FetchContent.cmake:1564 (cmake_parse_arguments):
The BUILD_COMMAND keyword was followed by an empty string or no value at
all. Policy CMP0174 is not set, so cmake_parse_arguments() will unset the
ARG_BUILD_COMMAND variable rather than setting it to an empty string.

If a PPP peer disconnects and then tries to reconnect it will send an 'LCP configure request' packet. The code that handles that scenario seems to be clearing the wrong lcp_state flag (LCP_RX_UP instead of LCP_TX_UP) and thus the nuttx ppp client will keep sending IPCP packets which are rightfully dropped by the new peer since it is still in the LCP negotiation phase.
