In some situations rtrlib does not release the locks for its internal
data structures before calling a callback. This can lead to deadlocks
when a lot of routes must be revalidated because the sync socket buffer
will fill up and block the rtrlib thread. The bgpd main thread then
waits for rtrlibs internal locks to be released indefinitely.
This is fixed by using nonblocking sockets instead of blocking ones and
setting a flag to revalidate everything, if it would block.

this function had to be used only inside zebra ( this was written in the
header vrf.h). To keep the functionality, a more generic API is used.

Make the wart slightly less bad... also there is still a possible write
after free here. This needs to be fixed again, properly, by some
structure changes.

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.

In order for connected routes to be installed the if_is_operative
function is called. This function checks the status of ptm
and decides to use ptm enabled/disabled on the interface.
The call to zebra_ptm_get_enable was returning true and causing
the interface subsystem to do the wrong thing. Modify the
internal bfd case to when checking for ptm enabled to say it
is not enabled.
