This adds support for f2fs casefolding. Similarly to ext4 casefolding,
this is controlled per-folder via the +F attribute. It can be toggled on
empty directories only. It is not currently compatible with encryption,
but that will likely change.
When enabling the casefold feature, use the -C flag. The format is:
-C encoding[:flag1,flag2,etc]

GCC 7.2.0 is unhappy with the usage of major/minor:
fibmap.c: In function ‘print_stat’:
fibmap.c:70:13: warning: In the GNU C Library, "major" is defined
by <sys/sysmacros.h>. For historical compatibility, it is
currently defined by <sys/types.h> as well, but we plan to
remove this soon. To use "major", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"major", you should undefine it after including <sys/types.h>.
printf("dev [%d:%d]\n", major(st->st_dev), minor(st->st_dev));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is because config.h is not included first, as a result, macros
defined in config.h is not recognized. So let's include f2fs_fs.h
before other header files.

These funcs are provided by sys/sysmacros.h, so include the header
directly. Building with alternative C libraries can fail otherwise
like so:

fibmap.c:36:32: warning: implicit declaration of function 'major' [-Wimplicit-function-declaration]
printf("dev [%d:%d]\n", major(st->st_dev), minor(st->st_dev));

printf("dev [%d:%d]\n", major(st->st_dev), minor(st->st_dev));

* removed unused includes.
* removed unused parameters.
* Fixed a bunch of warnings around:
int i;
if (i < some_uint) ...
and
u32 x;
...
if (x < 0) return error;
* Protect BLKDISCARD usage if it is not available.

Include sys/types.h for major/minor macros.
This fixes the following compile error with musl libc:

This patch shows devname and start_lba based on zero sector.
fibmap reports related lba, sometimes we want to know absolute lba of
file to compare with blktrace.
