Some consts for function arguments
Patch from Pavel Tvrdik
Add get_u64() and put_u64() into lib/unaligned.h
Include "lib/string.h" instead of <string.h>. It should give us bzero()and other non-portable functions on all systems.
Wrote real version of unaligned data access functions (needed for BGP).
Added generic functions for unaligned data access.
First look at data structures. More to come tomorrow...
