* For C, wchar_t is provided by the OS. On NuttX, it's uint16_t.
(Except wide character literals, which uses the compiler
built-in knowledge of wchar_t.)
* For C++, wchar_t is a built-in type. It's provided by the compiler.
* The compilers built-in wchar depends on the compiler configuration.
For the sim, the compilers are usually configured with wchar_t == int,
which is 32-bit.
* wchar_t should be compatible between C and C++.
This commit fixes the mismatches by telling the compiler to use
16-bit wchar_t.
An alternative is to make NuttX use 32-bit wchar_t if the compiler
is configured with 32-bit wchar_t. It can increase the runtime
footprint. While it might be ok for the sim, it might be a problem
for real devices.
let's call either nx_dup/nx_dup2 or file_dup/file_dup2
instead just like other fs api: xxx->nx_xxx->file_xxx

the argument passed to file_dup2 doesn't always come from task file list
so it doesn't make sense to hold the file list lock and then it is better
to do the protection in the new function files_dupfd2

An empty extension for sed -i is not widely available.
* Where it isn't available (eg. macOS's sed) "sed -i -e" will
create a backup file with the "-e" suffix.
* Even GNU sed documentation says it's "not recommended".
This commit deals with it by:
* Replace it with a more appropriate tool (kconfig-tweak)
* Or, specify the extension (.bak)
let's replace the content of file in place instead

NULL inode passed to files_allocate doesn't mark file struct in the
allocated state, so other threads which invovle in file allocation
(e.g. open or dup) may allocate the same file struct again.

Withtout this change, I was not able to read images built
with the following tools:
* https://github.com/igrr/mkspiffs
* spiffsgen.py from ESP-IDF
Introduce a new Kconfig option, SPIFFS_COMPAT_OLD_NUTTX,
for those who prefer to keep the on-disk (bug-to-bug?) compatibility
with the older NuttX.
If boardconfig changed, '/configure.sh -e board:config menuconfig'
would finally call 'make distclean menuconfig' which results in
build break. It also applies to nconfig and qconfig.
