This adds support for more complex alias handling, such as:
$ alias ls='ls -l'
Previously such an alias was not split into the command verb and the
argument correctly, instead the full alias string was handled as the
verb, which obviously fails.
This commit fixes this by expanding the alias, checking whether it has
arguments and if so, it merges the expanded alias + the old command line
together, resulting in a completely new command line.
Example (assuming the alias above has been created):
$ ls /bin
Results in a new command line: "ls -l /bin" which is then parsed and
executed.
switchboot <image path>
Switch to the updated or specified boot system. This command depends on
hardware support CONFIG_BOARDCTL_SWITCH_BOOT. `<image path>` point to a
partion or file which contain the firmware to boot.

boot [<image path> [<header size>]]
Boot a new firmware image. This command depends on hardware support
CONFIG_BOARDCTL_BOOT_IMAGE. <image path> may point to a partion or file
which contain the firmware to boot. The optional, numeric argument
<header size> may be useful for skipping metadata information preprended
to the firmware image.

CONFIG_FILE_STREAMS now defaults to 'n' when DEFAULT_SMALL is enabled. This
is a good change, but this source file fails to compile when file streams
are disabled.
Fix this by using dprintf.
Summary:
- I noticed that the ps command shows the wrong format due to
recent changes on sigmask length from 32bits to 64bits
- This commit fixes this issue
Impact:
- None
Testing:
- Tested with sabre-6quad:smp on qemu-7.1

ostest contains some logic that depends on internal implementation of signal sets and ostest must be updated to match those changes.
There is no particular impact from this PR. This PR is the result of impact from nuttx 8885.
Tested with nuttx 8885
A resulting word that is identified to be the command name word of a
simple command shall be examined to determine whether it is an unquoted,
valid alias name.
The keyword here being "a simple command", arguments are not subject to
expansion.
This adds support for string aliases into nsh. There are some nuances that
are not handled correctly yet:
- Reserved words can be overloaded, which is a clear POSIX violation
The parser is modified to detect, handle and remove quotes from the
command string. Whatever is inside the quotes is treated as a string
literal. If no matching end quote is found, the terminal prints out
and error.
Let remote machine handle special character except Ctrl-C, make cu's behavior more close to linux/bsd system.

The test consists of two parts:
- A tester that tries to trigger wrong states of work queue
- A verifier that checks whether the wqueue is still working properly
The tester is trying to queue and cancel work several times with
priority lower/same/higher than the work queue.
Most wrong cases are likely to happen with high priority like:
- If `cancel` never decreases semcount, the count may keep growing
and finally overflow
- If `cancel` is decreasing semcount too much, the `work_thread` may
be waken up less times than expected
The lower/same priority testers are just added for covering other
unexpected situations.
The verifier is trying to queue some works and check they are called as
expected:
- Frist queue a 'sleep' worker, to let a work queue thread be in busy
status and not waiting on sem, while other work queue thread(s) (if
any) still waiting for sem. If sem is in wrong state, it may cause
wrong behavior in either thread waiting/not waiting on the sem.
- Then queue a few count works, if the work queue(s) are still working
properly, these works should finally be all called once.

The timer is for connect timeout, but is not cancelled on connect error,
then it may be triggered after ftpc quit and cause heap-use-after-free.
