* Makefile: Enable -O2 to reduce CPU cycles used by code (especially 1wire code)
* onewire.h: Define separate functions for work in host mode and in client mode.
* onewire.c: Rename functions and variables for host mode. Define several macros
  	     for client mode. Define full set of functions for work in client mode,
	     but final `ow_client_send_rom' function not use generic
	     `ow_client_bit_io' function. Instead `ow_client_send_rom' use separate
	     code for read 1 byte and send 8 byte.
* bprocessor.c: Two new `lcd_display_*' functions. Also new logic of work: first we
  		get rom code from iButton key, then we send this code in cycle to
		door.
