Initial commit on integrated BIRD
New data types net_addr and variants (in lib/net.h) describing network addresses (prefix/pxlen). Modifications of FIB structures to handle these data types and changing everything to use these data types instead of prefix/pxlen pairs where possible. The commit is WiP, some protocols are not yet updated (BGP, Kernel), and the code contains some temporary scaffolding. Comments are welcome.
