Since zebra might be sending srcdest routes down to the various daemons,
they need to understand the presence of the field at the very least.
Sadly, that's also the best we can do at this point since none of the
protocols has support for handling srcdest routes. The only consistent
thing to do is to ignore them throughout.
If an administrator wants to have the srcdest route as non-srcdest in a
protocol, setting a non-srcdest static route (possibly blackhole) is
probably the best way to go.

This introduces ZAPI_MESSAGE_SRCPFX, and if set adds a source prefix
field to ZAPI IPv6 route messages sent from daemons to zebra. The
function calls all have a new prefix_ipv6 * argument specifying the
source, or NULL. All daemons currently supply NULL.
Zebra support for processing the field was added in the previous patch,
however, zebra does not do anything useful with the value yet.

The problem reported was that routers downstream from the ABR would have
prefixes in the IPv6 rib that should have been summarized. Testing showed
that the prefixes were absent in the lsdb but not removed from the rib.
The problem (and others) stemmed from determining the link-state id to use
for the area-range statement only from other entries in the range-table. Since
the area range statement creates inter-prefix LSAs (summaries) which are in all
aspects identical to other inter-prefix LSAs, the number space for the lsid
needs to be unique across all inter-prefix LSAs, not just unique between area
range statements. This fix removes the use of range-table specific lsids and
acquires the lsid just as any other inter-prefix LSA.

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.

Issue:
BFD client registrations are not being sent to PTM from BGP/OSPF clients when the quagga clients have no BFD configuration. This can create stale BFD sessions in PTM when BFD is removed from quagga configuration before quagga is restarted.
BFD client de-registrations from BGP/OSPF also go missing sometimes when quagga is restarted. This also will cause stale BFD sessions in PTM.
Root Cause:
BFD client registrations were being sent at the time of BGP/OSPF daemon initialization. But, they were being sent to zebra before the socket connection between zebra and BGP/OSPF was established. This causes the missing BFD client registrations.
BFD client de-registrations are sent from zebra when zebra detects socket close for BGP/OSPF daemons. Based on the timing, the de-registrations may happen after socket between PTM and zebra is closed. This will result in missing de-registrations.
Fix:
Moved sending of BFD client registration messages to zebra connected callback to make sure that they are sent after the BGP/OSPF daemons connect with zebra.
Added BFD client de-registrations for BGP/OSPF to be also sent when zebra daemon gets restart signal. They are sent from the signal handler only if it was not already handled in zebra client socket close callback.
Prior to this change, interface bandwidth could not be defined above 10G. With
the use of higher speed interfaces, the ability to effectively define the path
links was highly impacted. Additionally, the default auto-cost reference-bandwidth
for ospf and ospfv3 was set to 100M, which relects a much earlier time. Changed both
the range of interface bandwidth definitions and reference bandwidths to be up to
100G. Set the default interface bandwidth (if not defined) to 10G to make the ratio
continue to cause a cost of 10 as before. Manual testing as well as ospf-min and
ospf-smoke passed successfully.
