Add support for source-specific IPv6 routes to BIRD core This patch adds support for source-specific IPv6 routes to BIRD core. This is based on Dean Luga's original patch, with the review comments addressed. SADR support is added to network address parsing in confbase.Y and to the kernel protocol on Linux. Currently there is no way to mix source-specific and non-source-specific routes (i.e., SADR tables cannot be connected to non-SADR tables). Thanks to Toke Hoiland-Jorgensen for the original patch. Minor changes by Ondrej Santiago Zajicek.

Build system reworked to one global Makefile with includes and no nesting Also removed the lib-dir merging with sysdep. Updated #include's accordingly. Fixed make doc on recent Debian together with moving generated doc into objdir. Moved Makefile.in into root dir Retired all.o and birdlib.a Linking the final binaries directly from all the .o files.

Netlink on FreeBSD support Netlink support was added to FreeBSD recently. It is not as full-featured as its Linux counterpart yet, however the added subset is enough to make a routing daemon work. Specifically, it supports multiple tables, multipath, nexthops and nexthops groups. No MPLS support yet. The attached change adds 'bsd-netlink’ sysconf target, allowing to build both netlink & rtsock versions on FreeBSD.

Memory pages are not munmapped, instead we just madvise() Memory unmapping causes slow address space fragmentation, leading in extreme cases to failing to allocate pages at all. Removing this problem by keeping all the pages allocated to us, yet calling madvise() to let kernel dispose of them. This adds a little complexity and overhead as we have to keep the pointers to the free pages, therefore to hold e.g. 1 GB of 4K pages with 8B pointers, we have to store 2 MB of data.

Netlink: MPLS routes in kernel Anyway, Bird is now capable to insert both MPLS routes and MPLS encap routes into kernel. It was (among others) needed to define platform-specific AF_MPLS to 28 as this constant has been assigned in the linux kernel. No support for BSD now, it may be added in the future.
