1-wire improvements.

1) Functions reading bit from PAL now return ioline_t type.
2) Functions that handle acquired buffer with acquired bits
   now use uint8_t type because it corresponds to buffer type.
3) Cryptic bit shifting in bit storage functions replaced by
   dividion operations because all modern compilers perfectly
   optimise such operations.
