The vrrpd one conflicts with the standalone vrrpd package; also we're
installing daemons to /usr/lib/frr on some systems so they're not on
PATH.

Commit: ddbf3e6060
This commit modified the interface up handling code in
ZAPI such that the zclient handled the decoding for you.
Prior to this commit ospf assumed that it could use the
old ifp pointer to know state before reading the stream.
This lead to a situation where ospf would `smartly` track
and do the right thing in this situation. This commit
changed this assumption and in certain scenarios, say
a interface was changed after it was already up would
lead to situations where ospf would not properly handle
the new interface up.
Modify ospf to track data that is important to it in
it's interface->info pointer.
This code pattern was followed in both eigrp and pim.
In eigrp's case it was just behaving weirdly in any event
so fixing this pattern is not a big deal. In pim's
case it was not properly using this so it's a no-op
to fix.

Switch the zclient->interface_add functionality to have everyone
use the interface create callback in lib/if.c
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
Start the conversion to allow zapi interface callbacks to be
controlled like vrf creation/destruction/change callbacks.
This will allow us to consolidate control into the interface.c
instead of having each daemon read the stream and react accordingly.
This will hopefully reduce a bunch of cut-n-paste stuff
Create 4 new callback functions that will be controlled by
lib/if.c
create -> A upper level protocol receives an interface creation event
The ifp is brand spanking newly created in the system.
up -> A upper level protocol receives a interface up event
This means the interface is up and ready to go.
down -> A upper level protocol receives a interface down
destroy -> A upper level protocol receives a destroy event
This means to delete the pointers associated with it.
At this point this is just boilerplate setup for future commits.
There is no new functionality.

User pass the string match large-community 1 exact-match from CLI.
Now route map lib has got the string as "1 exact-match". It passes the string
to call back for compilation. BGP will parse this string and came to know
that for "1" it has to do exact match. Routemap lib has to save "1" in it’s
dependency table. Here routemap is saving this as a “1 exact-match”
which is wrong. The solution is used the compiled data.

Introducing a 3rd state for route_map_apply library function: RMAP_NOOP
Traditionally route map MATCH rule apis were designed to return
a binary response, consisting of either RMAP_MATCH or RMAP_NOMATCH.
(Route-map SET rule apis return RMAP_OKAY or RMAP_ERROR).
Depending on this response, the following statemachine decided the
course of action:
State1:
If match cmd returns RMAP_MATCH then, keep existing behaviour.
If routemap type is PERMIT, execute set cmds or call cmds if applicable,
otherwise PERMIT!
Else If routemap type is DENY, we DENYMATCH right away
State2:
If match cmd returns RMAP_NOMATCH, continue on to next route-map. If there
are no other rules or if all the rules return RMAP_NOMATCH, return DENYMATCH
We require a 3rd state because of the following situation:
The issue - what if, the rule api needs to abort or ignore a rule?:
"match evpn vni xx" route-map filter can be applied to incoming routes
regardless of whether the tunnel type is vxlan or mpls.
This rule should be N/A for mpls based evpn route, but applicable to only
vxlan based evpn route.
Also, this rule should be applicable for routes with VNI label only, and
not for routes without labels. For example, type 3 and type 4 EVPN routes
do not have labels, so, this match cmd should let them through.
Today, the filter produces either a match or nomatch response regardless of
whether it is mpls/vxlan, resulting in either permitting or denying the
route.. So an mpls evpn route may get filtered out incorrectly.
Eg: "route-map RM1 permit 10 ; match evpn vni 20" or
"route-map RM2 deny 20 ; match vni 20"
With the introduction of the 3rd state, we can abort this rule check safely.
How? The rules api can now return RMAP_NOOP to indicate
that it encountered an invalid check, and needs to abort just that rule,
but continue with other rules.
As a result we have a 3rd state:
State3:
If match cmd returned RMAP_NOOP
Then, proceed to other route-map, otherwise if there are no more
rules or if all the rules return RMAP_NOOP, then, return RMAP_PERMITMATCH.

Say, more than one sequence of a route-map uses the same named entity
in its match clause. After that entity is removed from any one of the
route-map sequences, any further changes made to that entity doesn't
dynamically take effect.
A reference counter, that allows the named entity to keep a count of
the route-maps dependent on it, has been introduced to address this issue.
