Qu Wenruo 425c950cc6 libbtrfsutil: Convert to designated initialization for QgroupInherit_type
[BUG]
When compiling btrfs-progs with libbtrfsutil on a python3.8 system, we
got the following warning:

  qgroup.c:110:2: warning: initialization of ‘long int’ from ‘void *’ makes integer from pointer without a cast [-Wint-conversion]
    110 |  NULL,     /* tp_print */
        |  ^~~~
  qgroup.c:110:2: note: (near initialization for ‘QgroupInherit_type.tp_vectorcall_offset’)

[CAUSE]
C definition of PyTypeObject changed in python 3.8.
Now at the old tp_print, we have tp_vectorcall_offset.

So we got above warning.

[FIX]
C has designated initialization, which can assign values to each named
member, without hard coding to match the offset.
And all the other uninitialized values will be set to 0, so we can save
a lot of unneeded "= 0" or "= NULL" lines.

Just use that awesome feature to avoid any future breakage.

Omar Sandoval bad4208da3 libbtrfsutil: add qgroup inheritance helpers
We want to hide struct btrfs_qgroup_inherit from the user because that
comes from the Btrfs UAPI headers. Instead, wrap it in a struct
btrfs_util_qgroup_inherit and provide helpers to manipulate it. This
will be used for subvolume and snapshot creation.
