*BREAKING changes*: func naming, types moved to br.h, etc...

- int types definitions moved to br.h
- bits_implementation() -> print_bitops_impl()
- 64 bitops use ...ll builtins instead of ...l
- add lsb and msb macros
- bit_for_each -> bit_for_each_1 (count from 1)
- bit_for_each_2 -> bit_for_each (count from 0)
