1) stream allocation cannot fail
2) some warnings were removed when functions safely ignored
the calling parameters being wrong.
3) some warnings were removed when functions did not consider
the state as an error since we did not return an error code.

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 Vrf aliases can be known with a specific hook. That hook will then,
from zebra propagate the information to the relevant zapi clients.
The registration hook function is the same for all daemons.

The problem is seen where speed mismatch caused ECMP route
not being reflected with correct number paths (NHs).
During cold boot, some interface speed updated by zebra as
part of one shot timer and triggers interface add to clients.
In this case, ospf already have created interface (bond interface),
but speed was not updated, trigger to do interface speed change
as part of interface add, which will trigger all Router LSA to
use updated speed into cost calculation.
Ticket:CM-22170
Testing Done:
Bring up CLOS config with Spine and leafs. Leaf have CLAG pair,
with same VRR ip address.
At spine one of the bond connecting to leaf node was having
higher speed than the paired device, With this fix, at spine (DUT)
bond interface speed is equal from all peer nodes.

The ospf_external_route_lookup function was not
being used so let's just remove it.
Unfortunately the removal was not quite so simple as
that ospf_asbr.h was being used to generate a reference
for the `struct ospf_route` data structure, so we
need to fix up the compile by fixing up header
inclusions so that ospf_route.h is actually included

In all but one instance we were following this pattern
with ospf_lsa_new:
ospf_lsa_new()
ospf_lsa_data_new()
so let's create a ospf_lsa_new_and_data to abstract
this bit of fun and cleanup all the places where
it assumes these function calls can fail.

* Stop headers from including themselves
* Use uniform relative include conventions

There is no need to check for failure of a ALLOC call
as that any failure to do so will result in a assert
happening. So we can safely remove all of this code.

Don't show BFD commands with timers since it might confuse users
("show running-config" won't display timers in client daemons anymore),
but keep accepting this command from previous configurations.

When BFD timers are configured, don't show it anymore in the daemon
side. This will help us migrate the timers command from daemons to
`bfdd`.

When calling route_map_finish, every place that we do we must
first set the deletion event to NULL, or we will create an infinite
loop, if we are using the delayed route-map application code.
As such we might as well just make the route_map_finish code
do this work, as that there is really no viable alternative here
and route_map_finish should only be called on shutdown.
This fixes an infinite loop in zebra on shutdown when there
are route-maps.

Programs that link to libnetsnmp must be compiled using a special set
of flags as specified by the "net-snmp-config --base-cflags" command
(whose output is stored in the SNMP_CFLAGS variable). The problem is
that "net-snmp-config --base-cflags" can output -std=c99 in addition to
other compiler flags in some platforms, and this breaks the build since
FRR souce code makes use of some GNU compiler extensions (e.g. allow
trailing commas in function parameter lists). In order to solve this
problem, append -std=gnu99 after SNMP_CFLAGS in all makefiles where this
variable is used. This way the -std=c99 flag will be overwritten when it's
present. Source files that don't link to libnetsnmp will be compiled using
either -std=gnu99 or -std=gnu11 depending on the compiler availability.
Fixes#1617.

Currently, interface packet transmit queue is created/deleted
as part of Interface UP/Down event. This results in
a rare condition where port came up but queue
was not created. The creation of queue occupies only few bytes.
Moving fifo queue creation to interface create
would add few bytes of fifo creation but at least it guaranteed
to be available during Up/down -->Up event.
Initialize ospf packet fifo queue during ospf
interface creation.
Drain queue during interface down event.
Drained and free the queue as part of the interface
delete/cleanup.
Ticket:CM-20744
Testing Done:
Bring up ospfv2 topology with multiple neighbors.
1) Trigger multiple shut/no shut events and validate
all queues are freed.
2) configure/deconfigure router ospf and validate
all ospf instance and interface underneath are freed.
