The issuing of `show bgp nexthop A.B.C.D` fails even if that
nexthop exists:
eva# show bgp nexthop 192.168.119.120
specified nexthop does not have entry
Fixed:
eva# show bgp nexthop 192.168.119.120

In bgp_open_option_parse the code is checking that the
stream has at least 2 bytes to read ( the opt_type and
the opt_length). However if BGP_OPEN_EXT_OPT_PARAMS_CAPABLE(peer)
is configured then FRR is reading 3 bytes. Which is not good
since the packet could be badly formateed. Ensure that
FRR has the appropriate data length to read the data.

As an example, Arista EOS allows this behavior.
Configuration something like:
```
neighbor PG peer-group
neighbor PG remote-as 65001
neighbor PG local-as 65001
neighbor 192.168.10.124 peer-group PG
```
Or without peer-group.

When more than 2 routers are present in LAN and the querier
goes down, the other routers will wait for other querier
present timer to expire to elect a new querier.
This issue will be seen when the router having next lower ip
address expires the other querier present timer first and it
starts sending the query message. Now on the other non-querier
routers it will receive this query and reset its other
querier present timer but the querier is still the old one
and since it is lowest ip, it never gets updated to the newly
elected querier.
Reset the other querier timer only if query is received from
the previously elected querier or a better new querier
This will make sure that non-querier elects the new querier
whose ip address is higher than the old querier
when the old querier goes down via other querier querier
timer expiry

The current service file configures restarts on-abnormal, which translates to "unclean signal", "timeout", or "watchdog". This patch updates it to always restart, as there's never really a time watchfrr should exit by itself at all.
