The MH datastructures were being released before the paths that were
referencing them. Fix is to do the MH cleanup last.
The MH finish function has also been stripped down to only do a
datastructure cleanup i.e. avoid sending route updates etc.

rpki config can be displayed in the 'show running-config'.
there is a fix to be done yet, this is related to the order of rpki per
vrf configuration. actually, the output is not saveable in the
running-config since the rpki commands are swapped. this prevents from
running rpki config at startup.
That commit also changes the identation, since rpki configure node was
with one extra space. reducing this, and add the changes for vrf
configuration too.

SIGHUP is ostensibly supposed to reload configuration
from a fresh slate. This is currently horribly broken
so much so that bgp just crashes. I see no point
in trying to make this work considering the yang
work coming down the pike.

Add -s X or --socket_size X to the bgp cli to allow

that hook is called back when default vrf name changes.
note that the hook is bgp_vrf_enable, and that the function is slightly
modified in order to be able to move bgp vrf instance from vrf to
default instance. for this, rfapi contexts are allocated.

Found that previous fix for this issue caused collatoral damage and
reverted that fix. This fix clears the vrf_bitmaps when the vrf is
disabled/deleted and then re-applies the redist config when the vrf
is re-enabled.

FRR_DAEMON_INFO should now contain an array of 'frr_yang_module_info'
structures describing the YANG modules implemented by the daemon.
This array will be used by frr_init() function to load all YANG modules

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.

Because a VRF name can be used for default VRF, or an alias of an
already created VRF can be passed as parameter, the default VRF name
must be found out. This avoids creating double BGP instances for
example.

The process of BGP shutdown hard free's memory irrelevant to

This option is only implemented by 4 daemons:
- BGPD
- RIPD
- RIPNGD
- Zebra
Manpages and documentation say that the option causes routes to not be
uninstalled from zebra when the daemon terminates. This is true for RIPD
and RIPNGD. This is not true for BGPD; in that daemon it only prevents
transmission of Cease / Peer Unconfig NOTIFICATION messages to peers.
Moreover, when any daemon disconnects from Zebra, all of its routes are
uninstalled from Zebra and the kernel regardless of this option,
rendering the option largely vestigial.
It is still useful in Zebra, where it prevents all routes from being
uninstalled when Zebra shuts down, so it is left there.

This capability, when used, is mapped over linux sys_admin capability.
This is necessary from the daemon perspective, in order to handle NETNS
based VRFs, because calling setns() requires sys admin capability.

NETNS is initialised from the VRF, instead of being directly called,
because this is not up to BGP daemon to initialise the various VRF
backend.
