Implement SP wire protocolsp
Implements the SP wire protocol, and infrastructure for legacy wire
protocol support.
Also added an XS_SERVICE_ID socket option to set the service id and renamed
the XS_PROTOCOL option to XS_PATTERN_VERSION.
The following pattern versions are supported:
PAIR: v3
PUBSUB: v1 (legacy), v4
REQREP: v2
PIPELINE: v3
SURVEY: v2
Note that all existing pattern versions have been bumped by 1 to allow for
use of legacy protocols (otherwise there would be no way to distinguish
between e.g. PUBSUB v3 and PUBSUB v3 using SP).
