Please follow API changes in most recent gpsd

[tegzed]

Hello,

I have noticed that Navit with the latest git version of Gpsd failes to compile (GPSD_API_MAJOR_VERSION 5 ). The gps_open() function's signature is changed in the most recent gpsd.Now it returns gps_data_t as a pointer argument rather than by return value. I have created a little patch (see attached diff file) to solve this problem, however I am not familiar with autoconf and couldn't write a check for gpsd API version to conditionally compile gps_open. Can anybody add this conditional check to the configure process?

This change also fixes a possible segfault when debugging is enabled, priv->source is freed before the debugging line:

dbg(0,"gps_open failed for '%s'. Retrying in %d seconds. Have you started gpsd?\n", priv->source, priv->retry_interval);

uses it.

Thanks, David Tegze

Another API change: gpsd's gps_poll() function is changed to gps_read() in most revent gpsd api version 5. the patch file (vehicle_gpsd.c.diff) is updated.

I updated the patch to support conditional compilation for gpsd API version 5 and older gpsds.
