Sort out some issues with PRN handling.
Add macros for classifying PRNs into GPS, GLONASS, DGPS. Document the PRN
ranges on the gps_json manual page.
It turns out that U.S. GPS authorities reserve 1-64 for GPS birds, not just
1-32. So the way we map GLONASS PRNs had to change. This required a
regression-test rebuild for the geostar driver.
