Convert stdio fmode to open(2) mode, filtering out zlib/bzlib flags.

 returns stdio[0] = NUL on error.
Todo:
glibc also supports ",ccs="
  • glibc: m use mmap'd input
  • glibc: c no cancel
  • gzopen: [0-9] is compession level
  • gzopen: 'f' is filtered (Z_FILTERED)
  • gzopen: 'h' is Huffman encoding (Z_HUFFMAN_ONLY)
  • bzopen: [1-9] is block size (modulo 100K)
  • bzopen: 's' is smallmode
  • HACK: '.' terminates, rest is type of I/O
