Merge quagga mainline into the google ISIS code.

The steps were:

  $ git checkout google-is-is
  $ git merge quagga
  $ git checkout google-is-is -- isisd

  # Resolve conflicts in the following:
  lib/md5.h
  zebra/rt_netlink.c
  zebra/zebra_rib.c
  zebra/zserv.c

Note that the content in the isisd directory is left unchanged in the
merge. As a result, changes made to isisd as part of the following
commits on the quagga mainline are dropped.

  # 8ced4e82 is the merge base, e96b3121 is the current quagga master
  $ git log --oneline --reverse 8ced4e82..e96b3121 -- isisd
