As part of the conversion to a `struct peer_connection` it will
be desirable to have 2 pointers one for when we open a connection
and one for when we receive a connection. Start this actual
conversion over to this in `struct peer`. If this sounds confusing
take a look at the bgp state machine for connections and how
it resolves the processing of this router opening -vs- this
router receiving an open. At some point in time the state
machine decides that we are keeping one of the two connections.
Future commits will allow us to untangle the peer/doppelganger
duality with this abstraction.

BGP tracks connections based upon the peer. But the problem
with this is that the doppelganger structure for it is being
created. This has introduced a bunch of fragileness in that
the peer exists independently of the connections to it.
The whole point of the doppelganger structure was to allow
BGP to both accept and initiate tcp connections and then
when we get one to a `good` state we collapse into the
appropriate one. The problem with this is that having
2 peer structures for this creates a situation where
we have to make sure we are configing the `right` one
and also make sure that we collapse the two independent
peer structures into 1 acting peer. This makes no sense
let's abstract out the peer into having 2 connection
one for incoming connections and one for outgoing connections
then we can easily collapse down without having to do crazy
stuff. In addition people adding new features don't need
to have to go touch a million places in the code.
This is the start of this abstraction. In this commit
we'll just pull out the fd and input/output buffers
into a connection data structure. Future commits
will abstract further.

Even if some of the attributes in bgp_path_info_extra are
not used, their memory is still allocated every time. It
cause a waste of memory.
This commit code deletes all unnecessary attributes and
changes the optional attributes to pointer storage. Memory
will only be allocated when they are actually used. After
optimization, extra info related memory is reduced by about
half(~400B -> ~200B).

When running all daemons with config for most of them, FRR has
sharpd@janelle:~/frr$ vtysh -c "show debug hashtable" | grep "VRF BIT HASH" | wc -l
3570
3570 hashes for bitmaps associated with the vrf. This is a very
large number of hashes. Let's do two things:
a) Reduce the created size of the actually created hashes to 2
instead of 32.
b) Delay generation of the hash *until* a set operation happens.
As that no hash directly implies a unset value if/when checked.
This reduces the number of hashes to 61 in my setup for normal
operation.

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].

The route-distinguisher string can be expressed in different
ways when the AS number is part of the RD. And the configured
string value has to be kept intact.
The following vty commands store the string value internally:
- router bgp / address-family ipv4 unicast / rd vpn export <>
- router bgp / address-family l2vpn evpn / rd <>
- router bgp / address-family l2vpn evpn / vni <> / rd <>
The vty commands where RD is configured in the below places is
not considered:
- router bgp / rfapi related commands
- router bgp / address-family xxx xxx / network .. rd <>

RD may be built based on an AS number. Like for the AS, the RD
may use the AS notation. The two below examples can illustrate:
RD 1.1:20 stands for an AS4B:NN RD with AS4B=65536 in dot format.
RD 0.1:20 stands for an AS2B:NNNN RD with AS2B=0.1 in dot+ format.
This commit adds the asnotation mode to prefix_rd2str() API so as
to pick up the relevant display.
Two new printfrr extensions are available to display the RD with
the two above display methods.
- The pRDD extension stands for dot asnotation format
- The pRDE extension stands for dot+ asnotation format.
- The pRD extension has been renamed to pRDP extension
The code is changed each time '%pRD' printf extension is called.
Possibly, the asnotation may change the output, then a macro defines
the asnotation mode to use. A side effect of forging the mode to
use is that the string could not be concatenated with other strings
in vty_out and snprintfrr. Those functions have been called multiple
times. When zlog_debug needs to display the RD with some other string,
the prefix_rd2str() old API is used instead of the printf extension.
Some code has been kept untouched:
- code related to running-config. Actually, wherever an RD is displayed,
its configured name should be dumped.
- bgp rfapi code
- bgp evpn multihoming code (partially done), since the logic is
missing to get the asnotation of 'struct bgp_evpn_es'.
