      Fix remaining pointer-signedness warnings for base64. · 1edcf521
      Niels Möller authored
      * sexp-transport-format.c (base64_encode_in_place): New helper
      function.
      (sexp_transport_vformat): Use it.
      
      * testsuite/base64-test.c (test_fuzz_once): Update to use char
      type where appropriate.
      (test_main): Use helper functions base64_encode_in_place and
      base64_decode_in_place (copied to this file).
      
      * tools/pkcs1-conv.c (base64_decode_in_place): New helper
      function.
      (decode_base64): Use it.
