Add a du command to NSH that recursively summarizes the size of each
path argument in 1K-blocks, or human-readable form with -h.
Supports -s (summary only), -a (all files), -d N (max-depth), and -h,
matching GNU du semantics.
Testing:
Built and ran on sim:nsh with:
```bash
cmake -B out/nuttx_sim_nsh -S nuttx -DBOARD_CONFIG=sim:nsh -GNinja
ninja -C out/nuttx_sim_nsh
./out/nuttx_sim_nsh/nuttx

Report password policy failures clearly from useradd and passwd when a
password does not meet complexity requirements.

Migrate passwd encrypt/verify to PBKDF2 modular crypt format using
kernel cryptodev (CRYPTO_PBKDF2_HMAC_SHA256 via /dev/crypto). Add
passwd_pbkdf2 wrapper, base64url helpers, complexity validation, and
pbkdf2_test for RFC 6070 vector coverage. FSUTILS_PASSWD selects
CRYPTO, ALLOW_BSD_COMPONENTS, and CRYPTO_CRYPTODEV so existing sim
defconfigs keep building. Change NSH_LOGIN_USERNAME default to root and
remove fixed-login password defaults.
BREAKING CHANGE: TEA-encoded /etc/passwd entries no longer verify.
Regenerate each entry after upgrading. Pair with the nuttx host mkpasswd
changes in apache/nuttx#19209. Boards must enable the appropriate
software or hardware crypto backend for PBKDF2 at runtime. When
CONFIG_NSH_LOGIN_FIXED=y, set CONFIG_NSH_LOGIN_PASSWORD in the board
defconfig or menuconfig; there is no default password.

Integrated SSH daemon authenticating against FSUTILS_PASSWD, with an
ECDSA P-256 host key and an NSH session over a PTY per connection. Built
from the upstream Dropbear tarball (pinned commit) and patched for
NuttX, using Dropbear's bundled libtomcrypt for all crypto. setsid()
(apache/nuttx#19184) and link() now come from NuttX, not local stubs.

Add minimal chmod/chown support to NSH using the
existing libc/VFS syscall interfaces.
Supported forms:
- chmod <octal-mode> <path>
- chown <uid>[:gid] <path>
The chown implementation supports the numeric
ownership forms already handled by the underlying
NuttX chown() implementation, including unchanged
uid/gid semantics via omitted fields.
Only numeric permission modes and numeric uid/gid
forms are supported in this initial implementation.
This adds interactive filesystem permission and
ownership management support to NSH and aligns the
shell more closely with standard POSIX environments.

BREAKING: In an effort to simplify board initialization logic for NuttX,
NSH will no longer support architecture initialization. This will happen
during boot via the BOARD_LATE_INITIALIZE option. The boardctl command
BOARDIOC_INIT is also no longer available from user-space.
Quick fix:
Any application relying on BOARDIOC_INIT should now enable
BOARD_LATE_INITIALIZE to have initialization performed by the kernel in
advance of the application running. If control over initialization is
still necessary, BOARDIOC_FINALINIT should be implemented and used.
Boards relying on NSH for initialization should also enable
BOARD_LATE_INITIALIZE instead.

1. Input redirect flags currently is hardcode, passing by arguments maybe better.
2. Only support redirect to path_name, redirect to fd is needed for pipeline.
Test
1. Redirect in
cat < /etc/init.d/rc.sysinit
2. Redirect with FIFO
mkfifo /dev/testfifo
cat /dev/testfifo &
ls > /dev/testfifo
3. NSH Params

This command looks through the currently running processes and kills
the those that match the selection criteria. This way system can send
signal to processes by name and without knowing the IDs.
Example (kill application hello):
pkill -15 hello
The command can be turned off by NSH_DISABLE_PKILL option and depends
on FS_PROCFS.

Currently NSH prompt is defined at build time, thus improper for AMP cases
where the same NSH binary is used on different nodes as the same NSH prompt
shows on all nodes.
This patch attempts to support runtime prompt string population from ordered
sources:
- the environment variable defined by NSH_PROMPT_ENV plus suffix
- the NSH_PROMPT_STRING
- the HOSTNAME plus suffix
The suffix is defined by NSH_PROMPT_SUFFIX so that to clearly separate the
command inputs.
Changes in `nshlib/`
- Kconfig: add configs NSH_PROMPT_MAX/ENV/SUFFIX etc
- nsh.h: adjust g_nshprompt defs, add nsh_update_prompt
- nsh_parse.c relocate g_nshpromt to nsh_prompt.c
- nsh_init.c revise to use nsh_update_prompt once
- nsh_session.c revise to use methods in nsh_prompt.c
- Makefile add nsh_prompt.c
- CMakeLists.txt add nsh_prompt.c
New additions in `nshlib/`
- nsh_prompt.c prompt related data structures and methods.
