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].

Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.

When rip is configured to work on secondary addresses
on an interface, rip was not properly sending out
the packets on secondary addresses because the source of the
packet was never properly being setup and rip would
send the packet out multiple times for the primary address
not once for each address on the interface that is setup to work.

Currently, it is possible to rename the default VRF either by passing
`-o` option to zebra or by creating a file in `/var/run/netns` and
binding it to `/proc/self/ns/net`.
In both cases, only zebra knows about the rename and other daemons learn
about it only after they connect to zebra. This is a problem, because
daemons may read their config before they connect to zebra. To handle
this rename after the config is read, we have some special code in every
single daemon, which is not very bad but not desirable in my opinion.
But things are getting worse when we need to handle this in northbound
layer as we have to manually rewrite the config nodes. This approach is
already hacky, but still works as every daemon handles its own NB
structures. But it is completely incompatible with the central
management daemon architecture we are aiming for, as mgmtd doesn't even
have a connection with zebra to learn from it. And it shouldn't have it,
because operational state changes should never affect configuration.
To solve the problem and simplify the code, I propose to expand the `-o`
option to all daemons. By using the startup option, we let daemons know
about the rename before they read their configs so we don't need any
special code to deal with it. There's an easy way to pass the option to
all daemons by using `frr_global_options` variable.
Unfortunately, the second way of renaming by creating a file in
`/var/run/netns` is incompatible with the new mgmtd architecture.
Theoretically, we could force daemons to read their configs only after
they connect to zebra, but it means adding even more code to handle a
very specific use-case. And anyway this won't work for mgmtd as it
doesn't have a connection with zebra. So I had to remove this option.

Most users of if_lookup_address_exact only cared about whether the
address is any local address. Split that off into a separate function.
For the users that actually need the ifp - which I'm about to add a few
of - change it to prefer returning interfaces that are UP.
(Function name changed due to slight change in behavior re. UP state, to
avoid possible bugs from this change.)
