Two similar CLI paths "nat44" and "nat44 add interface address"
caused unexpected behavior. If "nat44 add interface address"
command would fail the vlib cli processing function would
call "nat44" handler. This would also clean any previously
set errors from the first command and basically return
same error returned by "nat44" handler for every failed
command that starts with the same path string.
Fixes nat44-ed and nat44-ei plugin.

This patch affects how destination fib is choosen during session
creation. Default behavior of choosing fib based on output
interfaces is kept.
Configuration gives you the ability to change default behavior
to direct or restrict traffic between different FIB tables.
NAT specific VRF routing options:
a) keeping communication in the same VRF
b) option to add multiple destination VRFs
c) option to control the resolution order of destination VRFs
TX FIB resolution is based on looking up RX FIB entry in NATs
VRF table and picking the first FIB that resolves
destination address.

Implement proper state machine based on above RFCs. ACKs to SYNs/FINs
are no longer required/tracked. This is more friendly to peers and
accounts for lost packets and retransmits.
This change also means that all traffic is translated and forwarded
while in transitory timeout, which helps delivering e.g. retransmitted
FINs, FINACKs and other messages.
Also support reopening a session in transitory timeout after seeing both
FINs by seeing both SYNs again. This helps quick connection
reestablishment if the peers want to.

Change [1] put static mappings in flow hash. This change also broke
relationship between nat pool addresses and static mappings. Port and
address are no longer reserved in nat pool address records for a new
static mapping.
Because of this change both nat objects and their configuration can
function independently. This change also removed already broken logic of
having static-mapping-only configuration.
In this patch i have cleaned up and removed unnecessary logic for static
mapping configuration functions, address configuration functions,
interface configuraiton functions and all callback functions used for
resolving interface address bound records.
No more viable configuration option static-mapping-only is also removed
because there is no more option to run traffic through vpp for static
mappings without having flow hash table allocated. Instead user is now
able to create static mapping records without using nat pool addresses.
Fixed and improved management of required fib entries (ensuring VPP will
reply to ARP for all external addresses on outside interfaces) through
holding a refcount for their creation and removal.

This patch improves algorithm responsible for choosing nat pool address
during dynamic session creation.
Patch synchronizes nat pool address attributes with vpp interfaces doing
so gives nat option to determine correct nat pool address when creating
dynamic session.
Improvements:
* match dst address subnet and src fib with nat pool address
* for output-feature also fallback match of tx_sw_if_index with nat
pool address

Put static mappings in flow hash, drop existing hash tables used for
static mappings. Drop refcount variables and use hash table as a single
point of truth. Allow creating a static mapping conflicting with dynamic
mapping, which will take precedence after dynamic mapping is freed, so
that the existing flow can finish transferring data.

Fix coverity warning by initialising proto variable to a dummy value.
This value is never used because consuming function uses this
parameter value only if is_addr_only flag is not set and this flag is
always set if proto value is not provided by user.

Fixed FIB entry per interface, pool and
static mapping registrations in NAT control plane.
Improved FIB configuration handling in NAT -
added functions to generalize handling of FIB & NAT,
cleaned up interface callback functions. Changed "is_"
macros to inline functions for easier debugging.
