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.

It's migrated from e4crypt.

v2, migrate those micro defines for encrypt to f2fs internal,
drop unless of libsha etc.
