This code always used double-linked list before this rework in 8.0 that
introduced all these crashes and memory leaks. Using single-linked list
is actually a performance regression, because there are frequent removes
here and single-linked list obviously handles removes much worse.

Add a terse option to show bgp summary to shorten output.
Do not show the following information about the BGP
instances: the number of RIB entries, the table version and the used memory.
The "terse" option can be used in combination with the "remote-as", "neighbor",
"failed" and "established" filters, and with the "wide" option as well.
Before patch:
ubuntu# show bgp summary remote-as 123456
IPv4 Unicast Summary (VRF default):
BGP router identifier X.X.X.X, local AS number XXX vrf-id 0
BGP table version 0

Do a straight conversion of `struct bgp_info` to `struct bgp_path_info`.
This commit will setup the rename of variables as well.
This is being done because `struct bgp_info` is not descriptive
of what this data actually is. It is path information for routes
that we keep to build the actual routes nexthops plus some extra
information.

Problem reported that some bgp and ospf json commands did not return
any json output at all if the bgp/ospf instance did not exist.
Additionally, some bgp and ospf json commands did not return any json
output if the instance existed but no neighbors were defined. This
fix makes these commands more consistent in returning empty braces for
json output and issue a message if not using json output. Additionally,
made the flag "use_json" a bool to make it consistent since previously,
it had been defined as an int, char, u_char, and bool at various places.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

* bgpd/bgp_damp.c: Make bgp_damp_reuse_time_vty() accept a buffer and
