userspace: Add OXM field MFF_PACKET_TYPE
Allow packet type namespace OFPHTN_ETHERTYPE as alternative pre-requisite
for matching L3 protocols (MPLS, IP, IPv6, ARP etc).
Change the meta-flow definition of packet_type field to use the new
custom format MFS_PACKET_TYPE representing "(NS,NS_TYPE)".
Parsing routine for MFS_PACKET_TYPE added to meta-flow.c. Formatting
routine for field packet_type extracted from match_format() and moved to
flow.c to be used from meta-flow.c for formatting MFS_PACKET_TYPE.
Updated the ovs-fields man page source meta-flow.xml with documentation
for packet-type-aware bridges and added documentation for field packet_type.
Added packet_type to the matching properties in tests/ofproto.at.
If dl_type is unwildcarded due to later packet modification, make sure it
is cleared again if the original packet_type was not PT_ETH.
