Brandon Heller e9353ae079 Spec: Add _EPERM error codes 
An OpenFlow hypervisor might choose to reject an OpenFlow request, but
currently has no message type defined for this error. It is not a
vendor-specific error, thus we define an _EPERM error code for each error
type.

Also remove unused, commented-out text.

Brandon Heller cec522cd66 Spec: Clarify format for Strip VLAN action 
Clarify that the OFPAT_STRIP_VLAN action takes no argument and strips the
VLAN tag if one is present. The header is the generic action header.

Brandon Heller 16e2b8ba6d Spec: Clarify transaction ID for error messages 
Note that if an error is in response to a specific message from the
controller, the transaction ID should match that from the original
request.

Brandon Heller 4b969c68f3 Spec: Clarify matching for disabled STP ports 
Packets received on ports that are disabled by spanning tree must follow
the normal flow table processing path.

Brandon Heller 3a7d98b612 Spec: Clarify matching behavior for flow mods and stats 
The spec does not currently define how wildcard matching should behave for
flow modification (specifically DELETE and MODIFY commands) and stats.
This commit adds text to define behavior when some fields are wildcarded
and others are left exact.

Brandon Heller 0c370a5ef9 Spec: Remove distinction between Type 0 and Type 1 
People tend to get confused about "Type 0" and "Type 1" vs "Version 1.0" and
"Version 2.0".  To simplify, we'll drop the reference to types.

Mikio Hara 292ffb1f39 Barrier command: Add new protocol messages: barrier request and reply 
When a switch receives a barrier message it must first complete all
commands sent before the barrier message before executing any commands
after it. When all commands before the Barrier message have completed,
it must send a barrier reply message back to the controller.

Yiannis Yiakoumis a47208dc76 Flow mod behavior: Add a new flag to flow mods and flow conflict 
detection handler for table maintanance

Add a CHECK_OVERLAP flag to flow mods which requires the switch to do
the (potentially more costly) check that there doesn't already exist a
conflicting flow with the same priority. If there is one, the mod
fails and an error code is returned.

Brandon Heller b5525791b5 Spec: Notify controller of flows that are forcefully deleted 
Previously, a switch would only notify the controller when flows expired.
Now, when a switch is told to delete flows, it sends a flow expiration
message, enabling the controller to get packet and byte counts from
deleted flows. Without this, the controller must retrieve flow statistics
and then delete the flow, during which time the counts could change. This
could also aid in debugging if multiple applications or programs
controlling the same switch are deleting each others' flows.

This commit adds a OFPER_DELETE as a choice for the reason field of a flow
expiration.

Brandon Heller a00b917457 Spec: Selective flow expirations 
Make flow expirations per-flow-entry, rather than per-switch.

This commit should give controllers extra flexibility to decide when they
want expirations, will simplify the job of an OpenFlow hypervisor, and may
reduce CPU load at the switch.
