Add support for port mods in an OpenFlow 1.4 bundle, as required for
the minimum support level by the OpenFlow 1.4 specification. If the
bundle includes port mods, it may not specify the OFPBF_ATOMIC flag.
Port mods and flow mods in a bundle are always applied in order and
the consecutive flow mods between port mods are made available to
lookups atomically.
Note that ovs-ofctl does not support creating bundles with port mods.

This patch adds support for OFPR_ACTION_SET as the packet-in reason when
a Packet-In message is triggered by an output action within an
action-set. By default reason code OFPR_ACTION_SET is enabled for async
messages when Openflow 1.4+ is used. A test case is included.

When the Packet-In message is triggered by a group action, OFPR_GROUP is
passed internally as the reason. The wire_reason() function converts the
reason to OFPR_ACTION if the wire protocol is earlier than OF1.4.
The wire_reason() function also converts other unsupported reasons
(i.e., OFPR_ACTION_SET and OFPR_PACKET_OUT) to OFPR_ACTION if it detects
a wire protocol earlier than OF1.4.
By default reason code OFPR_GROUP for Packet-In will be enabled for
async messages as in ofconn_flush(). Upon a connection being established
with a controller, the protocol version is checked and OFPR_GROUP will
be disabled in async config if the protocol is lower than OF1.4. Any
controller running OF1.4+ is still be able to enable OFPR_GROUP at its
will without being affected by this check.
The patch also includes tests cases for both OF1.3 and OF1.4 to ensure
proper reason code is given for packet-in message triggered by group
action.

Converts the majority of docs over to use the Markdown language for
pretty printing on GitHub. It's a rough first convertion without
exploiting the full potential of Markdown at this point. Section
titles and indentation are fixed as needed. Minimal docs interlinking
is added.
