sflow: replace VAPI with DLAPI
Remove the requirement to coordinate between linux-cp and sflow at
build time via cmake. Also, remove 350 lines of awkward thread-forking
VAPI code. Replace it with a dynamically retrieved function from the
linux-cp plugin, called lcp_itf_pair_get_vif_index_by_phy().
Remove build inhibit based on Netlink headers, and only inhibit the
build for FreeBSD. This plugin can now run regardless of Linux CP
being built or loaded, and then return VPP ifIndex numbers instead.
Also, fix a flaky test where non-ephemeral source ports throw off
packet captures.
Type: improvement
