Add error handling for top level failures (not able to
execute command, unable to find vrf for command, etc.)
With this error handling we add a new zapi message type
of ZEBRA_ERROR used when we are unable to properly handle
a zapi command and pass it down into the lower level code.
In the event of this, we reply with a message of type
enum zebra_error_types containing the error type.
The sent packet will look like so:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

Also add appropriate hooks for clients to subscribe to for
handling these types of errors.

frr_with_mutex(...) { ... } locks and automatically unlocks the listed
mutex(es) when the block is exited. This adds a bit of safety against
forgetting the unlock in error paths & co. and makes the code a slight
bit more readable.

The correct cast for these is (unsigned char), because "char" could be
signed and thus have some negative value. isalpha & co. expect an int
arg that is positive, i.e. 0-255. So we need to cast to (unsigned char)
when calling any of these.

zvni setup in zebra is controlled via bgpd i.e. advertise_all_vni
from bgpd triggers this setup. As a part of zvni creation we may need
to setup BUM mcast SG entries which are propagated to pimd for MDT setup.
Now pimd may not be present at the time of zvni creation or may restart
post zvni creation so we need a mechanism to replay (on pimd startup) and
to cleanup (on pimd stop). This is addressed via zebra_vxlan_sg_replay and
zebra_evpn_pim_cfg_clean_up.

libunwind provides an alternate to backtrace() for printing out the call
stack of a particular location. It doesn't use the frame pointer, it
goes by the DWARF debug info. In most cases the traces have exactly the
same information, but there are some situations where libunwind traces
are better.
(On some platforms, the libc backtrace() also uses the DWARF debug info
[e.g.: ARM backtraces are impossible without it] but this is not the
case everywhere, especially not on BSD libexecinfo.)

Corrections so that the BGP daemon can work with the label manager properly
through a label-manager proxy. Details:
- Correction so the BGP daemon behind a proxy label manager gets the range
correctly (-I added to the BGP daemon, to set the daemon instance id)
- For the BGP case, added an asynchronous label manager connect command so
the labels get recycled in case of a BGP daemon reconnection. With this,
BGPd and LDPd would behave similarly.

The library changes add 3 new messages to exchange between daemons and
ZEBRA.
- ZEBRA_TABLE_MANAGER_CONNECT,
- ZEBRA_GET_TABLE_CHUNK,
- ZEBRA_RELEASE_TABLE_CHUNK,
the need is that routing tables identifier are shared by various
services. For the current case, policy routing enhancements are planned
to be used in FRR. Poliy routing relies on routing tables identifiers
from kernels. It will be mainly used by the future policy based routing
daemon, but not only. In the flowspec case, the BGP will need also to
inject policy routing information into specific routing tables.
For that, the proposal is made to let zebra give the appropriate range
that is needed for all daemons.

PR #1739 added code to leak routes between (default VRF) VPN safi and unicast RIBs in any VRF. That set of changes included temporary CLI including vpn-policy blocks to specify RD/RT/label/&c. After considerable discussion, we arrived at a consensus CLI shown below.
The code of this PR implements the vpn-specific parts of this syntax:
router bgp <as> [vrf <FOO>]
address-family <afi> unicast
rd (vpn|evpn) export (AS:NN | IP:nn)
label (vpn|evpn) export (0..1048575)
rt (vpn|evpn) (import|export|both) RTLIST...
nexthop vpn (import|export) (A.B.C.D | X:X::X:X)
route-map (vpn|evpn|vrf NAME) (import|export) MAP
[no] import|export [vpn|evpn|evpn8]
[no] import|export vrf NAME
User documentation of the vpn-specific parts of the above syntax is in PR #1937
