sbuf variable is used among other things to store IS-IS database output.
Future commits will introduce the output of extended access groups in
the "show isis database detail" output.
Extend the sbuf size to have chance to store all information.

Add a function to copy a bitfield_t structure.
Add a ‘void *’ to ‘word_t *’ converstion in bf_init() to avoid the
following error:

Filter out keys in JSON output with "grep -v" does not work when JSON
does not use the pretty format.
Use native python code to filter out keys.

When `bgp_evpn_vni_rt_cmd` deals with "both" type, it wrongly created
only one node ( should be two nodes ) for lists of both `vpn->import_rtl` and
`vpn->export_rtl`. At this time, the two lists are already wrong.
In `no route-target both RT`, it will free the single node from lists of both
`vpn->import_rtl` and `vpn->export_rtl`. After freed from `vpn->import_rtl`,
it is "use-after-free" at the time of freeing it from `vpn->export_rtl`.
It causes crash sometimes, or other unexpected behaviours.
This issue is introduced by commit `3b7e8d`, which have adjusted both
`bgp_evpn_vni_rt_cmd` and `bgp_evpn_vrf_rt_cmd`.
Since `bgp_evpn_vrf_rt_cmd/no_bgp_evpn_vrf_rt_cmd` works well again
unintentionally with commit `7022da`, only `bgp_evpn_vni_rt_cmd` needs to
modify - add two nodes for "both" type and some explicit comments for this
special case of "both" type.

BGP was modified in a0b937de42
to grab the peer->io_mtx before validating the header to ensure
that the input Queue was not being modified by anyone else at that
moment in time. Unfortunately validate_header can detect a problem
and attempt to relock the mutex, which deadlocks. This deadlock in
the bgp_io pthread is the lone deadlock at first, eventually though
bgp attempts to write another packet to the peer( say when the
it's time to send the next packet ) and the main pthread of bgpd
becomes deadlocked and then the whole bgpd process is stuck at that
point in time leaving us dead in the water.
The point of locking the mutex earlier was to ensure that the input
Queue wasn't being modified by anyone else, (Say reading off it )
as that we wanted to ensure that we don't hold more packets then necessary.
Let's grab the mutex long enough to look at the input Q size, this
ensure that we have room and then we can validate_header and do the right
thing from there. We'll need to lock the mutex when we actually move it
into the input Q as well.

Initial commit: 23b2a7ef52
changed the json output of `show bgp <afi> <safi> json` to
not have pretty print because when under a situation where
there are a bunch of routes with a large scale ecmp show
output was taking forever and this commit cut 2 minutes out
of vtysh run time.
Subusequent commit: f4ec52f7cc
changed this back.
When upgrading to latest version the long run time was noticed
due to testing. Let's add back this functionality such that
FRR can have reduced run times with vtysh when it's really
needed.
