Added methods to retrieve channels count, coalesce config params.
Changed DriverInfo method to return an exported struct.
Switched to golang.org/x/sys/unix from syscall. https://groups.google.com/forum/#!topic/golang-dev/cEASnHIXmLI
package syscall is locked down and should only be called by internal packages, external packages should use golang.org/x/sys
