openflow_input: add TLVs for LACP gentable
openflow_input: remove queue_get_config_request/reply

These messages are not part of the OF 1.4 standard. They were causing
java compile errors because the corresponding type enum values had
been removed from ofp_type.
java_model: more informative error msg for enum lookup failures

They are still triggered for a ton of different cases, where
the lookup target isn't really an enum in the first place.

This should be fixed.
OFVersion: add constant for OF1.4
java_gen: pass version to custom templates
java_gen: OFMatch add support for OF1.4 (and fix OF1.2)

pulled the custom Match code from OFMatchV3Ver13 out into generic
templates for OFMatchV3, that's included for OF1[234].
java_gen: add ChannelUtilsVer14

not really useful anymore, should get rid of it, but currently
still referenced from some generated code.
test_data: fix port_desc_stats_reply for Java

port_desc_stats_reply hat values for config and state that
do not correspond to valid enum value combinations, so it couldn't
be read by Java. Changed the values and added a Java definition for
full testing.

loci: automatically derive show emitters

Previously you needed to add a macro for each (member type, member name). This
was a common stumbling block for people contributing to the input files. Now
you only need to modify LOCI's show code if you want to customize how the field
is displayed (hex, for example).

loci: use class metadata in push_wire_values

This needs the same special cases as build_class_metadata, but they weren't in
sync.
loci: inline push_wire_values into new

The difference between push_wire_types and push_wire_values was always
confusing. Now that push_wire_values is simple enough we can inline it.
