Add a function to check if the route_info array
has all types specified with data in it. Specifically,
test the 'key' attribute for non-zero data. Ignore
ZEBRA_ROUTE_SYSTEM as it should be zero key anyway.

With flooding control added recently we were not properly handling
the new flood control parameter in zebra_vxlan.c handler functions.
The error message that was being repeatedly seen:
2019/05/01 00:47:32 ZEBRA: [EC 100663311] stream_get2: Attempt to get out of bounds
2019/05/01 00:47:32 ZEBRA: [EC 100663311] &(struct stream): 0x7f0f04001740, size: 22, getp: 22, endp: 22
The fix was to ensure that both the _add and _del functions kept proper
sizing of amount of data read *and* the _del function was not
reading the flood_control data from the stream.

Solve issue #4198
Link-ID and Remote IP address must be set accordingly to the interface type
(Point-to-Point or Broadcast) from the neighbor information. However, this
information are only valid once the Network State Machine (NSM) is Full i.e.
when the adjacency is up. The original TE code only look to Interface State
Machine (ISM) change which not allow to collect valid neighbor information.
The patch move setup of Link-ID and Remote-IP TE parameters from
ospf_mpls_te_ism_change() to ospf_mpls_te_nsm_change() function.

Again, the FIFO_* stuff in lib/fifo.h is no different from a simple
unsorted list. Just use DECLARE_LIST here so we can get rid of FIFO_*.

Historically, isisd has been carrying around its own red-black tree to
manage its LSP DB in. This replaces that with the newly-added
DECLARE_RBTREE_*. This allows completely removing the dict_* code.

Typesafe red-black tree, built out of the OpenBSD implementation and the
macro soup layered on top. API compatible with skiplists & simple
lists.
Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
By the power of the C preprocessor, these macros provide type-safe
warppers for simple lists, skiplists and hash tables. Also, by changing
the instantiation macro, it is easily possible to switch between
algorithms; the code itself does not need to be changed since the API
is identical across all algorithms.

The upcoming gRPC-based northbound plugin will run on a separate
pthread, and it will need to have access to the running configuration
global variable. Introduce a rw-lock to control concurrent access
to the running configuration. Add the lock inside the "nb_config"
structure so that it can be used to protect candidate configurations
as well (this might be necessary depending on the threading scheme
of future northbound plugins).

The ability to lock the running configuration to prevent other users
from changing it is a very important one. We already supported
the "configure exclusive" command but the lock was applied to
the CLI users only (other clients like ConfD could still commit
configuration transactions, ignoring the CLI lock). This commit
introduces a global lock for the running configuration that is
shared by all northbound clients, and provides a public API to
manipulate it. This way other northbound clients will also be able
to lock/unlock the running configuration if required (the upcoming
gRPC northbound plugin will have RPCs for that).
NOTE: this is a management-level lock for the running configuration,
not to be confused with low-level locks used to avoid data races.

Problem reported that route-maps applied to "ip protocol table bgp"
would not be invoked if the ip protocol table command was issued
after the bgp prefixes were installed. Found that a recent change
improving how often nexthop_active_update runs missed causing this
filtering to be applied. This fix resolves that issue as well as
a couple of other places that were problematic with the recent
change.
