* pack.c (pack_pack, pack_unpack): 'm0' format (base64) complies with

  RFC 4648.  It adds no line feed when encoding, and raise ArgumentError
  if the encoded string contains non-alphabet (including CR and LF).

* lib/base64.rb: added.  This provides encoding/decoding method for
  Base64 in standard RFC 2045, Base64 in standard RFC 4648 and ``Base 64
  Encoding with URL and Filename SafeAlphabet'' in RFC 4648.

* test_pack.c, test/base64/test_base64.rb: add tests for above.
