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.
