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.

When braces (optional parameters) are used in the quagga parser, there
was a small leak on every iteration. Since this construct is primarily
used in the configuation process rather than show commands, it was not
readily apparent. With the addition of the "show ip bgp {json}" form of
the commands, each time one was run, memory was leaked.

In "lib/cli: reduce strcmp in CLI hot paths", I failed to notice that
CMD_VARIABLE as a boolean test covers a superset of the other types of
variables. Thus, the patch broke processing of IP/IPv6/Integer range
parameters in the CLI.
Fix by some reordering and introducing TERMINAL_RECORD macro (which
marks whether a given terminal type is a parameter) to be used in places
where the check is really for all kinds of variables.
