fixes #143 Protocols and transports should be "configurable"
This makes all the protocols and transports optional. All of them except ZeroTier are enabled by default, but you can now disable them (remove from the build) with cmake options. The test suite is modified so that tests still run as much as they can, but skip over things caused by missing functionality from the library (due to configuration). Further, the constant definitions and prototypes for functions that are specific to transports or protocols are moved into appropriate headers, which should be included directly by applications wishing to use these. We have also added and improved documentation -- all of the transports are documented, and several more man pages for protocols have been added. (Req/Rep and Surveyor are still missing.)
