Replace the LSDB callbacks with LSA update and delete hooks using the
the FRR hook mechanism. Remove redundant callbacks by placing the LSA
update and delete hooks in a single place so that deletes don't need
to be handled by the update hook. Simplify existing OSPF TE and OSPF
API Server callbacks now that there is no ambiguity or redundancy.
Also cleanup the debugging by separating out opaque-lsa debugging
from the overloaded event debugging.

When originating a default AS-External LSA in one OSPF instance,
it wasn't working if the criteria route was installed by another OSPF
instance. This required more flexible processing of the OSPF external
route information.
Also fix problem multi-instance display for "show ip ospf
<instance> database ...".

Under certain timing conditions, the current logic asserts in
ospf_lsa_refresh_delay(). While this isn't readily reproducible,
the only explanation is that the conversion from struct timeval
to milliseconds is 0 due to rounding off the microseconds.

The configured OSPF refresh interval was not being used for opaque LSA (it always used the constant). Also, modified the timers lsa min-arrival command to have a maximum of 5000 msecs as well as providing a path for backward command compatibility.
Added missing user documentation for both timers lsa min-arrival and timers throttle lsa all.

Our standard says when in a .h file and declaring a function all parameters
must have their variables spelled out. Let's do this for ospf_lsa.h
Modified ospf_lsa.c to also use event instead of thread, and uint8_t instead
of unsigned short.

Include an event ptr-to-ptr in the event_execute() api
call, like the various schedule api calls. This allows the
execute() api to cancel an existing scheduled task if that
task is being executed inline.

When setting an loopback's cost, set the value to 0, unless the operator
has assigned a value for the loopback's cost.
RFC states:
If the state of the interface is Loopback, add a Type 3
link (stub network) as long as this is not an interface
to an unnumbered point-to-point network. The Link ID
should be set to the IP interface address, the Link Data
set to the mask 0xffffffff (indicating a host route),
and the cost set to 0.
FRR is going to allow this to be overridden if the operator specifically
sets a value too.

This is a first in a series of commits, whose goal is to rename
the thread system in FRR to an event system. There is a continual
problem where people are confusing `struct thread` with a true
pthread. In reality, our entire thread.c is an event system.
In this commit rename the thread.[ch] files to event.[ch].

Problem:
Multiple memory leaks after pr12366
RCA:
ospf_lsa_unlock was not happening for the few of the LSAs in
ospf_lsa_refresh_walker after pr12366 due to which memory
related to lsas was leaking.
Fix:
Moved the ospf_lsa_unlock outside if check.

Description:
After area range config, summary lsas are aggerated to configured
route but later it was being flushed instead of the actual summary
lsa. This was seen when prefix-id of the aggregated route is same
as one of the actual summary route.
Here, aggregated summary lsa need to be returned to set the flag
SUMMARY_APPROVE after originating aggregated summary lsa but its not.
Which is being cleaned up as part of unapproved summary cleanup.
Corrected this now.
Issue: #13028
Signed-off-by: Rajesh Girada <rgirada@vmware.com>
Description:
OSPF ABR will summarise the networks based on configured range
and re-advtertise the summarised route. But if configured range
prefix id is same as one of the subset of routes prefix id then
as per rcf2328 Appendex-E recommendation, it will prepare the LSID and originate.
While re-advertising, it is using ospf LSDB instead of area specific
LSDB which is making it fail to re-advertise the summary lsa.
Fixed this by passing correct LSDB pointer.

Description:
Code changes involves.
1. Count the no.of router LSAs received with DC options bit set,
supporting do not age(DNA).
2. If no of router LSAs received with DC bit set is equal to total
no of LSAs in the router lsdb, then all the routers in the
area support do not age processing.
3. Flood the self originated LSAs with DNA flag if all routers in the area
supports the feature.
4. Stop aging of the LSAs recived with DO_NOT_AGE bit set from
other routers.
5. Self originated DO_NOT_AGE lsas will still be aging in their own
database.

Steps to reproduce:
--------------------------
1. ANVL: Establish full adjacency with DUT for neighbor Rtr-0-A on DIface-0 with DUT as DR.
2. ANVL: Listen (for up to 2 * <RxmtInterval> seconds) on DIface-0.
3. DUT: Send <OSPF-LSU> packet.
4. ANVL: Verify that the received <OSPF-LSU> packet contains a Network- LSA for network N1
originated by DUT, and the LS Sequence Number is set to <InitialSequenceNumber>.
5. ANVL: Establish full adjacency with DUT for neighbor Rtr-0-B on DIface-0 with DUT as DR.
6. ANVL: Listen (for up to 2 * <RxmtInterval> seconds) on DIface-0.
7. DUT: Send <OSPF-LSU> packet.
8. ANVL: Verify that the received <OSPF-LSU> packet contains a new instance of the
Network-LSA for network N1 originated by DUT, and the LS Sequence Number
is set to (<InitialSequenceNumber> + 1).
Both the test cases were failing while verifying the initial sequence number for network LSA.
This is because currently OSPF does not reset its LSA sequence number when it is going down.

Description:
ospf process is crashing when the current router acts
as GR helper and it received a new lsa.
Here, ospf_lsa_different() is being called without checking
'old' pointer. It is asserted in ospf_lsa_different() api
if the 'old' pointer is NULL.
corrected this by validaing old pointer before calling
ospf_lsa_different() api.
