This change fixes NuttX’s CMake support when NuttX is embedded
in another project via add_subdirectory(). CMake’s CMAKE_SOURCE_DIR
and CMAKE_BINARY_DIR refer to the outermost project, causing NuttX
to access its .config, generated files, host tools, and build artifacts
in the parent project’s directories. The fix introduces NUTTX_DIR and
NUTTX_BINARY_DIR, based on CMAKE_CURRENT_SOURCE_DIR and
CMAKE_CURRENT_BINARY_DIR, and consistently uses them for NuttX
self-references while preserving existing standalone builds. It fixes
the Kconfig initialization failure reported in #19697 and allows an
embedded sim:nsh build to configure, build, and boot successfully.
The change affects only the CMake build system (not Make or Kconfig
defaults), requires the corresponding nuttx-apps change, and does not
extend add_subdirectory() support to cross-compiled non-sim boards due
to CMake’s toolchain-file limitation.
Fixes#19697.

During the Toybox port to NuttX, Claude noticed that changes in the
menuconfig weren't taking affect. This issue exists for a long time on
NuttX, in fact BayLibre's presentation from 2017 make jokes about our
building system not been reliable:
https://www.youtube.com/watch?v=XUJK2htXxKw&t=320s
Stale archive members from $(AR)'s additive-only behavior can linger
after Kconfig toggles change which files provide a symbol, causing dead
weight or "multiple definition" link errors on incremental builds.
Fixed by splitting ARCHIVE into two macros: ARCHIVE keeps the original
additive behavior for apps/libapps.a, which many independent
subdirectories contribute to across a build, while the new
ARCHIVE_REBUILD deletes then archives for the far more common case
of a single Makefile building its own self-contained $(OBJS)
- all 39 such call sites now use it.

There was another small issue on sixlowpan_input.c code, it was
processing protosize and 8-bit instead of 16-bit.
It was working because the max tcp->tcpoffset was 0xf0, so
protosize = ((uint16_t)tcp->tcpoffset >> 4) << 2;
Will be protosize = 15 * 4 = 60 and will fit inside 8-bit.

Both the UART and PTY serial drivers previously assumed all
VT100/ANSI escape sequences were fixed 3-byte CSI sequences, causing
longer CSI and SS3 key sequences (such as Home, End, Delete, and
modified keys) to leak stray characters into the terminal when local
echo was enabled. This patch replaces the fixed-length logic with a
state machine that correctly recognizes and suppresses escape
sequences of any length, while preserving the data delivered to
applications. The change only affects local echo behavior, is fully
backward compatible, and has been validated with both interactive NSH
sessions and automated PTY tests.
