Because there is no pre-encoding length of the ssid, the ssid including
the Chinese characters whose length is less than 32 after encoding
cann't be translated.
For example, the ssid name is `word人`. After encoding it is `world\xe4\xba\xba` and will not be decoded.

These flags are not used in the code.
SERIAL_HAVE_RXDMA and SERIAL_HAVE_TXDMA flags are used instead.
STM32_UART_TXDMA flag is not even defined in Kconfig
Connecting the static page tables to each other was done with the page
table virtual address (riscv_pgvaddr) when the page table physical address
is needed.
I can never remember whether the static page table list contains the
table's physical or kernel virtual address.. Add the fact as a comment
there.
Also add the limitations that come from this static page table approach
for Sv32.
1. fs_epoll: try again when epoll_teardown() return 0
when poll_notify() called larger than twice when epoll_wait() blocked
in the eph->sem, the semcount will be larger than 1 when epoll_wait()
unblocked and will return 0 directly at the next epoll_wait.
So retry to wait the eph->sem again when epoll_teardown return 0.
2. fs_epoll: poll_setup the fd again even this fd got non-expected event
Some poll implementations need call poll_setup again when their internal
states changed (e.g., local socket), so should add the fd to the epoll
teardown list and poll_setup again at the next epoll_wait even this fd
got the user non-expected event.

The SSID can be configured with special symbols suach as single
quotations, double quotations and backslashes, which need to be escaped.

In `drivers/rptun/rptun.c`, we have a `rptun_is_recursive` function,
which lets rptun thread run recursively. Then the `usrsock_rpmsg_ept_cb`
may be called inside `usrsock_rpmsg_ept_cb`, which can cause some
unexpected behavior, so we add a queue to keep the order of incoming
messages to reduce the complexity.

Add a minimal implementation to suppress warnings when building
application code shared with other operating systems.
For example:
When building with a c++ compiler and GCC 12.2.0, the following warning is emitted:
nuttx/include/spawn.h:178:40: warning: statement has no effect [-Wunused-value]
178 | #define posix_spawnattr_destroy(attr) (0)

This adds option to do PMP configuration via mpfs_board_pmp_setup instead
of just opening up everything. In this case, it is up to the specific
board to implement the PMP configuration in whichever way it sees fit.
Set the newly spawned process's signal mask, if the caller has instructed
to do so by setting POSIX_SPAWN_SETSIGMASK.
This is called after the task has been created but has NOT been started
yet.
Like the name implies, it is supposed to set the spawn attributes for
the NuttX specific "spawn proxy task" which was historically used as
a proxy to spawn new tasks. The proxy handled file actions and the signal
mask which are inherited from the parent.
The proxy task does not exist anymore, thus the proxy task attributes
do not need to be set anymore either.
Also, the function is currently still used, but the signal mask is set
for the spawning process, not the proxy process, and this is most
DEFINITELY an error (as the spawning process's signal mask changes
unexpectedly).
Setting the signal mask for the newly spawned process is simple, just
set it directly, if instructed to do so. This will be done in a later
patch!
