vnet: create L2 feature arc infrastructure

This commit adds two new nodes in the L2
datapath in input and output direction respectively.

These nodes fork the traffic into three feature
arcs: ip4, ip6 and nonip, which later join
to continue the usual L2 processing.
The vnet_l2_feature_enable_disable() function
with the same signature as
vnet_feature_enable_disable() takes care of
enabling the L2 datapath feature bits as needed, when
the features are enabled/disabled.

Thus, L2 features may use the similar plumbing as

function, with the assumption that the current_data in the buffer is at
the L3 header. This is not the case for the single loop fastpath,
where the vlib_buffer_advance() call is made after the call to
determine_next_node(), as a day1 behavior. As a result - that path
incorrectly sets the l3_hdr_offset.

Solution: move the vlib_buffer_advance() call to before determine_next_node()

vnet: ethernet-input incorrectly sets l3_hdr_offset in some cases

The issue surfaced when developing the tap GSO code, with
an iteration where output path is reliant on
vnet_buffer (b0)->l3_hdr_offset being set correctly in
the input path, during performance testing.

Adding a workaround in the TX path shows that
the issue surfaces only for relatively few packets
during the test (about 100 out of 600000).

Analysis shows the issue arises if the ethernet-input
is handling two untagged packets with different sw_if_index
values - then the accelerated path punts to slow path,
before the setting of the l2.l2_len values is done,
thus resulting in them being 0, and l3_hdr_offset being
the same as l2_hdr_offset, wreaking havoc on TX path.

The solution is to move the l2_hdr_offset calculation
into a place where it is done for all the packets,
and move the l3_hdr_offset calculation into
the determine_next_node() function - as that function is
also the one setting the special-case l2.l2_len value for
tagged packets and moving the current_data for the L2 case.

acl-plugin: tuplemerge: avoid batch-resize of the applied entries vector - VPP-1352

If the number of rules within a given partition exceeds the limit,
the split_partition() might get called, in which we calculate
the relaxed mask, create a new partition with that mask and
attempt to reallocate some entries from the overcrowded partition.

The non-TM code was pre-expanding the vector with rules by
the number of rules in the new ACL being applied - which
caused the split_partition() to iterate over the rules
filled with zeroes. Most of the time it is benign, but
if a newly created relaxed partition is such that these
entries can be "relocated", then the code attempts to
do so, which does not end well.
