Ticket:
This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.
The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.
bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use. This is bad practice and would break when the
memtype are made static.

We realize VRFs with linux netns by default. The main job is
to associate a VRF with a netns. Currently this is done by
the configuration:
[no] vrf N netns <netns-name>
This command is also available in vtysh and goes to only
zebra, because presently only zebra supports multiple VRF.
A file descriptor is added to "struct vrf". This is for the
associated netns file. Once the command "vrf N netns NAME"
is executed, the specified file is opened and the file
descriptor is stored in the VRF N. In this way the
association is formed.
In vrf_socket(), we first switch to the specified VRF by
using the stored file descriptor, and then can allocate
a socket which is working in the associated netns.

zebra: atomic FIB updates

This removes the BSD specific usage of struct sockaddr_dl
hardware address. This unifies to use explict hw_addr member for
the address, and zebra specific enumeration for the link layer
type.
Additionally the zapi is updated to never send platform specific
structures over the wire, but the ll_type along with hw_addr_len
and hw_addr are now sent for all platforms.
Based on initial work by Paul Jakma.

The IPv6 RA code also receives ICMPv6 RS and RA messages.
Unfortunately, by bad coding practice, the buffer size specified on
receiving such messages mixed up 2 constants that in fact have different
values.
The code itself has:
#define RTADV_MSG_SIZE 4096
While BUFSIZ is system-dependent, in my case (x86_64 glibc):
/usr/include/_G_config.h:#define _G_BUFSIZ 8192
/usr/include/libio.h:#define _IO_BUFSIZ _G_BUFSIZ
/usr/include/stdio.h:# define BUFSIZ _IO_BUFSIZ
As the latter is passed to the kernel on recvmsg(), it's possible to
overwrite 4kB of stack -- with ICMPv6 packets that can be globally sent
to any of the system's addresses (using fragmentation to get to 8k).
(The socket has filters installed limiting this to RS and RA packets,
but does not have a filter for source address or TTL.)
Issue discovered by trying to test other stuff, which randomly caused
the stack to be smaller than 8kB in that code location, which then
causes the kernel to report EFAULT (Bad address).
