f40e2bc270 Nest: Fix bug in recursive routes with MPLS-labeled nexthops 
When a recursive route with MPLS-labeled nexthop was exported to kernel
and read back, the nexthop_same() failed due to different labels_orig
field and kernel protocol reinstalled it unnecessarily.

For comparing hext hops, route cache has to distinguish ones with
different labels_orig, but KRT has to ignore that, so we need two
nexthop compare functions.

Thanks to Marcel Menzel for the bugreport.

In attribute cache, adata structures were stored densely in one memory
block, without regard to alignment. Let's force at least u32 alignment.

bcf2327425 BGP: Send hold timer 
Implement BGP Send hold timer according to draft-ietf-idr-bgp-sendholdtimer.
The Send hold timer drops the session if the neighbor is sending keepalives,
but does not receive our messages, causing the TCP connection to stall.

3fb06fea1d BGP: Add options to require BGP capabilities 
Some BGP capabilities change the BGP behavior in a significant way, so if
the configuration depends on it, it is better to not establish BGP
session when the capability is not available.

Add several BGP option to require individual BGP capabilities during
session negotiation.

b5e9e5197b MPLS: Fix issue with recursive MPLS routes 
Recursive MPLS routes used hostentry from the original route, which

c5c3a22bcc Conf: Bytestrings with hex: should use the same general format as ones without. 
Either hex:01234567, or hex:01:23:45:67. No confusing formats like
hex:0123:4567🆎cdef, which looks like there is an implicit zero byte.

e83beb70bd KRT: Allow to learn routes with RTPROT_KERNEL 
The Kernel protocol, even with the option 'learn' enabled, ignores
direct routes created by the OS kernel (on Linux these are routes
with rtm_protocol == RTPROT_KERNEL).

Implement optional behavior where both OS kernel and third-party routes
are learned, it can be enabled by 'learn all' option.

ba01a6f2e6 MPLS: Handle compatibility with old configs 
Old configs do not define MPLS domains and may use a static protocol
to define static MPLS routes.

When MPLS channel is the only channel of static protocol, handle it
as a main channel. Also, define implicit MPLS domain if needed and
none is defined.

6a242b3ec6 IO: Fix race condition in event processing 
When regular event was added from work event, we did remember that

reconfiguration.

d8130da86b BGP, L3VPN: Fix MPLS channel reload 
When a MPLS channel is reloaded, it should reload all regular MPLS-aware
channels. This causes re-evaluation of routes in FEC map and possibly
