843b10c8b0 Nest: Handle non-MPLS on MPLS case in recursive route update
When non-MPLS recursive route resolves to MPLS underlying route,
then it should get MPLS labels from the the underlying route.

9eace84342 Nest: Handle PtP links in recursive route update
Underlying (IGP) route may lead to PtP link, in this case it does not
need gateway. Which is different than direct route without gateway.

When recursive (BGP) route uses PtP route, it should not use recursive
next hop as immediate next hop, while for direct routes it should.

759b204be3 Lib: Support for 64-bit numbers in bvsnprintf()
Use 'l' for s64/u64 instead of for long/ulong, as that is much more
useful. Also make number() correct with regard to signed/unsigned
typecasts.

24493e9169 Fixed undefined behavior on signals.
The C11 specification allows only sig_atomic_t and _Atomic variable
access. All other accesses to global variables are undefined behavior.

Using int was probably OK on x86 and x86_64; yet there were some reports
from other architectures (especially some MIPS) that in rare cases,
after issuing SIGHUP, BIRD did strange things.

3f477ccb03 Filters: Function body comparison result now used.
Function bodies were compared in post-parse time, yet the result was not
used and the functions were incorrectly considered the same as before.

Now the result is used to reload affected protocols.

b7d7599ce3 BGP: implement Adj-RIB-Out
The patch implements optional internal export table to a channel and
hooks it to BGP so it can be used as Adj-RIB-Out. When enabled, all
exported (post-filtered) routes are stored there. An export table can be
examined using e.g. 'show route export table bgp1.ipv4'.

f6a6a77640 BGP: Fix 'deterministic med' to work with 'merge paths'
The 'deterministic med' option is implemented by suppressing other than
best-in-group routes (grouped by ASN) from best route selection. This
interferes with 'merge paths' as supressed routes are no longer mergable
with best route. This is fixed by suppressing only those routes that are
not mergable with best-in-group route.

should be called 'graceful restart' instead of 'graceful down', as the
later should be reserved for graceful shutdown in style of RFC 8326.

18f70a6229 Nest: VRF of protocol can be explicitly specified as 'default'
Protocol can have specified VRF, in such case it is restricted to a set
of ifaces associated with the VRF, otherwise it can use all interfaces.

The patch allows to specify VRF as 'default', in which case it is
restricted to a set of iface not associated with any VRF.
