Follow up commit for [1] in response to the request to make the mount
behaviour configurable whether the number of free clusters is read
from the fsinfo section or computed (as the white paper suggests).
Default is the original behaviour of NUTTX, just read fsinfo.

Since 7a046358d9 the top-level COPYING
file has been deleted and replaced by DISCLAIMER, LICENSE, and NOTICE
files. However, some references to the old COPYING file remained in
Kconfig help text and documentation.

* Updates stale references to the old top-level COPYING file to
either LICENSE or NOTICE (or both), as appropriate in each
instance.
New CONFIG_FAT_LFN_UTF8: UTF8 strings are converted to UCS2-LFN
Bugfix in fat_createalias: space is now also converted to underbar.
Change (bugfix) in fat_getlfname: init characters (0xff) and '\0' are rewound as well.
Pullreq FAT improvements
* NuttX: Add CONFIG_FAT_LFN_ALIAS_HASH to speed up creating long filenames.
Long filenames on FAT filesystems have associated 8.3 character alias
short filenames. The traditional form of these is FILENA~1.EXT with
a running count of the number of similar names. However creating this
unique count can take several seconds if there are many similarly named
files in the directory. Enabling FAT_LFN_ALIAS_HASH uses an alternative
format of FI0123~1.TXT where the four digits are a hash of the original
filename. This method is similar to what is used by Windows 2000 and
later.
* NuttX: Add CONFIG_FAT_LFN_ALIAS_TRAILCHARS alternative format for 8.3 filenames.
Traditional format for long filename 8.3 aliases takes first 6
characters of long filename. If this option is set to N > 0,
NuttX will instead take first 6-N and last N characters to form
the short name. This is useful for filenames like "datafile12.txt"
where the first characters would always remain the same.
* NuttX: FAT32: Fix file date corruption in fat_truncate().
* NuttX: if SD card wait seems to be a long one, give time for other threads to run.
