The "uuid/" directory is actually part of the include path. This usually still
works because most people have the path one level up in their default include

Current Makefile.am included the 'include' directory
directly as -I./include, but this doesn't guarantee that
said directory exists when building outside of the source
directory.
By adding $(srcdir) instead of '.' this gets fixed automatically.

Add a copy command to f2fs_io, to allow testing direct I/O writes where
the source page is from a different file (mmap) or an internal kernel
page (sendfile). It could be useful for other tests in the future too.

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
