* changed data format of text files for save/restore (looks like C/C++ structures,
similar to the format used in old save/restore branches)
* don't set the initial value of shadow bool parameters
* don't set the initial value of bool parameters twice
* cpu/init.cc: missing #undef added
* ne2k.cc: variable tx_timer_active was never set to 1 (type now bx_bool)
* floppy.cc: missing initialization of the 'eot' array in reset() added
* pic.h: type of member 'byte_expected' changed to Bit8u
* pit_wrap.h: unused members removed
