This patch introduces a new parser helper, parse_u64_with_suffix(),
which has a better error handling, following all the parse_*()
helpers to return non-zero value for errors.
This new helper is going to replace parse_size_from_string(), which
would directly call exit(1) to stop the whole program.
Furthermore most callers of parse_size_from_string() are expecting
exit(1) for error, so that they can skip the error handling.
For those call sites, introduce a wrapper, arg_strtou64_with_suffix(),
to do that. The only disadvantage is a little less detailed error
report for why the parse failed, but for most cases the generic error
string should be enough.

The fixes involve the following changes:
- Unexport functions which are not utilized out of the file
* print_path_column()
* parse_reflink_range()
* btrfs_list_setup_print_column()
* device_get_partition_size_sysfs()
* max_zone_append_size()
- Include related headers before implementing the function
* change-uuid.c
* convert-bgt.c
* seed.h
- Add missing headers caused by the above header changes
* include <uuid/uuid.h> for tune/tune.h.

The CI build on musl warns:

On glibc the header directly includes fcntl.h.

[FALSE ALERT]
Unlike gcc, clang doesn't really understand the comments, thus it's
reportings tons of fall through related errors:
cmds/reflink.c:124:3: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
case 'r':
^
cmds/reflink.c:124:3: note: insert '__attribute__((fallthrough));' to silence this warning
case 'r':
^
__attribute__((fallthrough));
cmds/reflink.c:124:3: note: insert 'break;' to avoid fall-through
case 'r':
^
break;
[CAUSE]
Although gcc is fine with /* fallthrough */ comments, clang is not.
[FIX]
So just introduce a fallthrough macro to handle the situation properly,
and use that macro instead.
