[PATCH nft 0/4] remove xfree() and add free_const()+nft_gmp_free()

[Thomas Haller <thaller@redhat.com>]

- add and use a nft_gmp_free() for freeing memory allocated by gmp.
- add a free_const() for the many places where we intentionally want
  to free a const pointer. It still just wraps free(), as the name
  indicates. Unlike xfree(), which sounds as if xmalloc()/xfree()
  were a distinct set of allocators.
- drop xfree() and use plain free() (or free_const()) everywhere.

Thomas Haller (4):
  datatype: don't return a const string from cgroupv2_get_path()
  gmputil: add nft_gmp_free() to free strings from mpz_get_str()
  all: add free_const() and use it instead of xfree()
  all: remove xfree() and use plain free()
