  * btrfs_list_setup_print_column()
  * device_get_partition_size_sysfs()
  * max_zone_append_size()

- Include related headers before implementing the function

David Sterba 5c663502bf btrfs-progs: build: use plain fcntl.h instead of sys/fcntl.h
The CI build on musl warns:

    [CC]     cmds/balance.o
In file included from cmds/inspect.c:19:
/usr/include/sys/fcntl.h:1:2: warning: #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h> [-Wcpp]
    1 | #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h>
      |  ^~~~~~~

On glibc the header directly includes fcntl.h.

Qu Wenruo 3a1d4aa089 btrfs-progs: fix fallthrough cases with proper attributes
[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.
