To ensure we read all the datagrams availabe from a socket when the
read task is scheduled, make the read helper return and error or
continue enum and loop unitl an error is received.
This requires the read from the socket to be non blocking

Let's cleanup the ospf6_sendmsg api and not pass in a pointer
to the ifindex to use. It's an integer.
Also remove the assert(*ifindex); We never use ifindex of 0

1. The socket() call is changed to vrf_socket().
2. The ospf6 instance creation api added.
3. The global socket fd is replaced with ospf6->fd.
4. All dependency of the global socket is resolved.
5. Added the ospf6 receive timer in the global structure.
6. Performed the thread off on receive timer when we do "no router ospf6".

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.

If we fail to set any socket's buffer size, try again with a smaller value
and keep going until it succeeds. This is better than just giving up or,
even worse, abort the creation of a socket (ospf6d and ripd).

Since we have autoconf results from a wide swath of target platforms, we
can go remove checks that have the same result on all systems.
This also removes several "fallback" implementations of functions that,
at some point in the history, weren't available on all target platforms.

When sending ancillary data on OpenBSD, we need to tell the compiler
that the ancillary data buffer should be aligned on the stack to the
minimum alignment of the first ancillary data object that will be sent.
Additionally, HAVE_SIN6_SCOPE_ID is not defined anywhere, check for
HAVE_STRUCT_SOCKADDR_IN6_SIN6_SCOPE_ID instead.

Fix lots of warnings. Some const and type-pun breaks strict-aliasing
warnings left but much reduced.
* bgp_advertise.h: (struct bgp_advertise_fifo) is functionally identical to
(struct fifo), so just use that. Makes it clearer the beginning of
(struct bgp_advertise) is compatible with with (struct fifo), which seems
to be enough for gcc.
Add a BGP_ADV_FIFO_HEAD macro to contain the right cast to try shut up
type-punning breaks strict aliasing warnings.
* bgp_packet.c: Use BGP_ADV_FIFO_HEAD.
(bgp_route_refresh_receive) fix an interesting logic error in
(!ok || (ret != BLAH)) where ret is only well-defined if ok.
* bgp_vty.c: Peer commands should use bgp_vty_return to set their return.
* jhash.{c,h}: Can take const on * args without adding issues & fix warnings.
* libospf.h: LSA sequence numbers use the unsigned range of values, and
constants need to be set to unsigned, or it causes warnings in ospf6d.
* md5.h: signedness of caddr_t is implementation specific, change to an
explicit (uint_8 *), fix sign/unsigned comparison warnings.
* vty.c: (vty_log_fixed) const on level is well-intentioned, but not going
to fly given iov_base.
* workqueue.c: ALL_LIST_ELEMENTS_RO tests for null pointer, which is always
true for address of static variable. Correct but pointless warning in
this case, but use a 2nd pointer to shut it up.
* ospf6_route.h: Add a comment about the use of (struct prefix) to stuff 2
different 32 bit IDs into in (struct ospf6_route), and the resulting
type-pun strict-alias breakage warnings this causes. Need to use 2
different fields to fix that warning?
general:
* remove unused variables, other than a few cases where they serve a
sufficiently useful documentary purpose (e.g. for code that needs
fixing), or they're required dummies. In those cases, try mark them as
unused.
* Remove dead code that can't be reached.
* Quite a few 'no ...' forms of vty commands take arguments, but do not
check the argument matches the command being negated. E.g., should
'distance X <prefix>' succeed if previously 'distance Y <prefix>' was set?
Or should it be required that the distance match the previously configured
distance for the prefix?
Ultimately, probably better to be strict about this. However, changing
from slack to strict might expose problems in command aliases and tools.
* Fix uninitialised use of variables.
* Fix sign/unsigned comparison warnings by making signedness of types consistent.
* Mark functions as static where their use is restricted to the same compilation
unit.
* Add required headers
* Move constants defined in headers into code.
* remove dead, unused functions that have no debug purpose.

SYMPTOM:
With quagga running on Linux, 'ifdown <if-name>' followed by 'ifup <ifname>
can cause OSPFv3 to not receive Hello packets on the interface.
ISSUE:
Operating System's interface IPv6 readiness may not be guaranteed at the
time of interface-up event. Thats because the ipv6 components in an OS may
also be listening to the same interface-up event that (in this case) is
relayed to OSPFv3.
In this failure case, setsockopt with option IPV6_JOIN_GROUP on the interface
returned EINVAL.
Error logs -
OSPF6: Zebra Interface state change: swp1 index 3 flags 11043 metric 1 mtu 1500
OSPF6: Interface Event swp1: [InterfaceUp]
OSPF6: Network: setsockopt (20) on ifindex 3 failed: Invalid argument
FIX:
To take care of this possible race condition, any address-family related
setting should be retried. Given it's a rare condition and window of this
race should be short, the patch adds a limited retry mechanism for the
IPV6 membership setting on the socket.

IPv6 supports the same concept of differentiated service for routing
protocols as IPv4, but like too many things, the standards committee
decided that having two names for the same thing wasn't good enough and
introduced a third more generic term transport class.
The socket option to set transport class works the same as IPv4, but the
arguments are different.
