The eigrp->eiflist is a linked list and should just
be a hash instead. The full conversion to a hash
like functionality is goingto wait until the connected
eigrp data structure is created.

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.

This code addition allows eigrp to set/unset the router-id
value. At this point I am not 100% sure that we do all the necessary
rework when a router-id changes. But on startup if read in before
a network statement we should be ok.

In eigrp we were using a uint32_t to hold the `struct in_addr` data
for the router id values. This caused us to do unnecessary conversions
pre and post for in/out. Let's just use the standard `struct in_addr`

a distribute_ctx context pointer is returned after initialisation to the
calling daemon. this context pointer will be further used to do
discussion with distribute service. Today, there is no specific problem
with old api, since the pointer is the same in all the memory process.
but the pointer will be different if we have multiple instances. Right
now, this is not the case, but if that happens, that work will be used
for that.
distribute-list initialisation is split in two. the vty initialisation
is done at global level, while the context initialisation is done for
each routing daemon instance.
babel daemon is being equipped with a routing returning the main babel
instance.
also, a delete routine is available when the daemon routing instance is
suppressed.
a list of contexts is used inside distribute_list. This will permit
distribute_list utility to handle in the same daemon to handle more than
one context. This will be very useful in the vrf context.

The keychain authentication code under eigrp was
using the wrong argv numbers for keychain lookup. Convert

I do not actually know if this allows eigrp authentication to

Ignore the return value of some functions in the places we know they
can't fail, and other small fixes.
Regarding the change in bgpd/rfapi/rfapi_rib.c, asserting that
rfapiRaddr2Qprefix() didn't fail is the common idiom inside the rfapi
code.

This improves code readability and also future-proofs our codebase

This is an important optimization for users running FRR on systems with
a large number of interfaces (e.g. thousands of tunnels). Red-black
trees scale much better than sorted linked-lists and also store the
elements in an ordered way (contrary to hash tables).
This is a big patch but the interesting bits are all in lib/if.[ch].

If the user configures some command that is already in the config we
should return CMD_WARNING instead of CMD_WARNING_CONFIG_FAILED
Using the previously-added vty_frame() support, this gets rid of all the
pointless empty "interface XYZ" blocks that get added for any interface
that shows up in the system (e.g. dummys, tunnels, etc.)
