ip: Protocol Independent IP Neighbors

Type: feature

- ip-neighbour: generic neighbour handling; APIs, DBs, event handling,
aging
- arp: ARP protocol implementation
- ip6-nd; IPv6 neighbor discovery implementation; separate ND,
MLD, RA
- ip6-link; manage link-local addresses
- l2-arp-term; events separated from IP neighbours, since they are not
the same.

vnet retains just enough education to perform ND/ARP packet
construction.
arp and ip6-nd to be moved to plugins soon.

misc: Fix python scripts shebang line

Type: fix

Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python'
as a valid shebang line. It requires scripts to explicitly chose
between python2 or python3.

api: autogenerate api trace print/endian

In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files.
In two formats, "custom-dump" and "dump". "dump" gives a human friendly list,
and "custom-dump" is meant to give a list of commands that can be fed to VAT.
This patch only deals with "dump".
Prior to this fix, auto-generation was only done for the basic types.
This fix adds support for any type, including lists, and supports pretty-printing
of enums, strings, IP addresses, MAC addresses and so on.

Usage: api trace dump <api-trace-file>

For example

fib: fib api updates

Enhance the route add/del APIs to take a set of paths rather than just one.
Most unicast routing protocols calcualte all the available paths in one
run of the algorithm so updating all the paths at once is beneficial for the client.
two knobs control the behaviour:
is_multipath - if set the the set of paths passed will be added to those
that already exist, otherwise the set will replace them.
is_add - add or remove the set

is_add=0, is_multipath=1 and an empty set, results in deleting the route.

It is also considerably faster to add multiple paths at once, than one at a time:

vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11
100000 routes in .572240 secs, 174751.80 routes/sec

init / exit function ordering

The vlib init function subsystem now supports a mix of procedural and
formally-specified ordering constraints. We should eliminate procedural
knowledge wherever possible.

The following schemes are *roughly* equivalent:

static clib_error_t *init_runs_first (vlib_main_t *vm)
{
clib_error_t *error;

... do some stuff...

if ((error = vlib_call_init_function (init_runs_next)))
return error;
...
}
VLIB_INIT_FUNCTION (init_runs_first);

and

static clib_error_t *init_runs_first (vlib_main_t *vm)
{
... do some stuff...
}
VLIB_INIT_FUNCTION (init_runs_first) =
{
.runs_before = VLIB_INITS("init_runs_next"),
};

The first form will [most likely] call "init_runs_next" on the
spot. The second form means that "init_runs_first" runs before
"init_runs_next," possibly much earlier in the sequence.

Please DO NOT construct sets of init functions where A before B
actually means A *right before* B. It's not necessary - simply combine
A and B - and it leads to hugely annoying debugging exercises when
trying to switch from ad-hoc procedural ordering constraints to formal
ordering constraints.

API: Fix shared memory only action handlers.

directly. That breaks Unix domain socket API transport.

registred interest. That scheme never worked correctly.

acl-plugin: acl-as-a-service: VPP-1248: fix the error if exports.h included in more than one C file

Including the exports.h from multiple .c files belonging to a single plugin results in an error.

Rework the approach to require the table of function pointers to be filled in by
the initialization function.

Since the inline functions are compiled in the "caller" context,
there is no knowledge about the acl_main structure used by the ACL
plugin. To help with that, the signature of inline functions is slightly
different, taking the p_acl_main pointer as the first parameter.

That pointer is filled into the .p_acl_main field of the method
table during the initialization - since the calling of non-inline variants
would have required filling the method table, this should give
minimal headaches during the use and switch between the two methods.

ACL based forwarding

A poor man's flow switching or policy based rounting.

An ACL is used to match packets and is associated with a [set of] forwarding paths
that determine how to forward matched packets - collectively this association is a
'policy'.
Policies are then 'attached', in a priority order, to an interface when thaey are
encountered as an input feature. If a packet matches no policies it is forwarded
normally in the IP FIB.

This commit is used to test the "ACL-as-a-service" functionality,
which currently compiles, and the existing traffic ACL tests pass in both hash and linear modes.
