This commit implements stderr redirection in HSN, support
Bash-like syntax for redirecting standard error output.
Support both foreground and background commands.
example:
- nsh> ls noexists 2> err.log
- nsh> ls noexists 2> err.log &
- nsh> ls noexists 2>> err.log
- nsh> sh < /dev/ttyS0 > /dev/ttyS0 2> /dev/ttyS1 &
- nsh> sh < /dev/ttyS0 > /dev/ttyS0 2>&1 &

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

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
set name `uname`
echo $name

Locking the scheduler prior to calling posix_spawn() might lock the
scheduler for a relatively long time, if the file to be loaded is large.
posix_spawn() loads the process into memory, possibly linking it as well
if the binary format is linkable (elf). This can take tens / hundreds of
milliseconds, which basically destroys the OS's real time performance.
Missing the death-of-child signal is a very trivial penalty considering
the alternative.
When an application is used as a loadable ELF module, the priority and
stack size of the application task is always fixed at the default values.
This commit changes to get the priority and stack size of the application
from the bulitin list. If it is not on the list, it still works as before.
1.Remove void cast for function because many place ignore the returned value witout cast
2.Replace void cast for variable with UNUSED macro
