This triggers `mm_free_delaylist()` before dumping status in PROTECTED
build, otherwise the `free` command still shows delaylist as `used`.

According to the POSIX standard, `fstat` and `stat` should return 0
(`OK`) on success. This commit changed the underlying `spiffs`
implementation to follow the POSIX standard.
Unbinding `ff_currentcluster` and `f_pos`:
1. Added `ff_pos` in `struct fat_file_s`.
2. Added function `fat_zero_cluster` for doing zeroing for gap
between EOF and new position beyond EOF.
3. Added function `fat_get_sectors` for getting the sector where
`f_pos` is located, allocting new cluster when `f_pos` is beyond
EOF.
4. Modify function `fat_read`, and `fat_write` with above functions.
5. Remove redundant logics in `fat_seek` since now new cluster is
allocated when writing instead of seeking.

pointer comparison is unsigned, when returning -errno will be converted
to a large positive number, can not enter the error handling branch,
therefore, the error code is returned directly and the sem is returned
through the parameters.

otherwise, it will only remove inode.

Pre-allocated files to avoid allocator access during thread creation
phase, For functional safety requirements, increase
CONFIG_NFILE_DESCRIPTORS_PER_BLOCK could also avoid allocator access
caused by the file descriptor exceeding the limit.
For Task Termination, the time consumption will be reduced ~3us (Tricore TC397 300MHZ):
10.65(us) -> 7.35(us)
NOTE:
This commit will not waste of extra heap, just pre-allocates the list of files for task_group.

Currently at runtime it is hard to know the exact build config of
the current NuttX instance. Thus it is inconvenient when there are
multiple configs for the same board. This patch attempts to solve
the issue by adding build config to /proc/version.

When we close a socket fd, it will call get path on sockets.
`close(socket_fd)` -> `file_closelk(filep)` -> `file_fcntl(F_GETPATH)`
It causes a heavy stack load for each socket close operation.
(We have `GETPATH` for sockets to be used for `fdinfo`)
But the socket fds are not intended to be used for file locks.
And so do some other file types, so we may just limit the usage of flock.
