We shouldn't have platform-agnostic code (e.g. zebra/interface.c)
calling platform-specific functions (e.g. netlink_neigh_update).
This commit introduces the kernel_neigh_update() function, which then
has to be implemented by all supported platforms. Currently only Linux
implements this function, which is only used by the RTADV code.

Testing Done: Manual testing succesful. bgp-min and ospf-smoke successful. redistribute-neighbor-smoke
has the same failures as the base image.
Problem was due to considering imported /32 arp entries as elible next-hops for other routes
(in this case a static route.) This confuses the rib since this next-hop is considered both
recursive and onlink. Disallowed the use of this imported arp entry in next-hop determination.
Added a default log file named /var/log/quagga/Quagga.log to every daemon
to capture log entries if no log file is defined. This also allows the
capture of logged information prior to reading each daemon's config file.
If a log file is defined manually, it will override this default file name.

Resolved several memory leaks caused by ifdown/ifup the vrf device or
a swp port. For bgp/zebra/ospf/ospf6, bouncing the vrf device would cause
a linked list, Interface, and route-table to get leaked. For ospf6,
bouncing the swp device also caused leaks of Connected and Prefix entries.

Testing: Unit, PTM smoke, OSPF smoke, BGP Smoke
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.
Some bitfields for zebra_debug_* flags were being modified
with bitwise operators instead of the purpose-built macros
in lib/zebra.h. Changed such instances to use the macros.

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.
