[PATCH nft v2 0/8] fix compiler warnings with clang

[Thomas Haller <thaller@redhat.com>]

Building with clang caused some compiler warnings. Fix, suppress or work
around them.

Changes to v1:
- replace patches
    "src: use "%zx" format instead of "%Zx""
    "utils: add _NFT_PRAGMA_WARNING_DISABLE()/_NFT_PRAGMA_WARNING_REENABLE helpers"
    "datatype: suppress "-Wformat-nonliteral" warning in integer_type_print()"
  with
    "include: drop "format" attribute from nft_gmp_print()"
  which is the better solution.
- let SNPRINTF_BUFFER_SIZE() not assert against truncation. Instead, the
  callers handle it.
- add bugfix "evaluate: fix check for truncation in stmt_evaluate_log_prefix()"
- add minor patch "evaluate: don't needlessly clear full string buffer in stmt_evaluate_log_prefix()"

Thomas Haller (8):
  netlink: avoid "-Wenum-conversion" warning in dtype_map_from_kernel()
  netlink: avoid "-Wenum-conversion" warning in parser_bison.y
  datatype: avoid cast-align warning with struct sockaddr result from
    getaddrinfo()
  evaluate: fix check for truncation in stmt_evaluate_log_prefix()
  src: rework SNPRINTF_BUFFER_SIZE() and handle truncation
  evaluate: don't needlessly clear full string buffer in
    stmt_evaluate_log_prefix()
  src: suppress "-Wunused-but-set-variable" warning with
    "parser_bison.c"
  include: drop "format" attribute from nft_gmp_print()
