Qu Wenruo a528cbeead libbtrfsutil: Convert to designated initialization for BtrfsUtilError_type
[BUG]
When compiling btrfs-progs with libbtrfsutil on a python3.8 system, we
got the following warning:

  error.c:169:2: warning: initialization of ‘long int’ from ‘void *’ makes integer from pointer without a cast [-Wint-conversion]
    169 |  NULL,      /* tp_print */
        |  ^~~~
  error.c:169:2: note: (near initialization for ‘BtrfsUtilError_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.
Also, uninitialized values will be 0, so we can also save a lot of
unneeded "= 0" or "= NULL" lines.

Just use that awesome feature to avoid any future breakage.

Omar Sandoval 23c01b3c1b libbtrfsutil: add Python bindings
The C libbtrfsutil library isn't very useful for scripting, so we also
want bindings for Python. Writing unit tests in Python is also much
easier than doing so in C. Only Python 3 is supported; if someone really
wants Python 2 support, they can write their own bindings. This commit
is just the scaffolding.
