Review request for marble.


Summary
-------

This completes offline routing by adding support for the generation of human readable instructions for both gosmore and routino. With this committed, we can start working on an important use case: Dynamic, offline route adjustments on Maemo (automatically calculate a new route when the user deviates too much from the original one).

The patch is based on gosmore-instructions [1] and planned to fully replace it. Gosmore-instructions is already used in [2] and I plan to continue supporting this usage. Therefore a new binary routing-instructions is included (replacing the former gosmore-instructions) similar to Marble's tilecreator. It is meant to be used on a webserver and therefore kept minimalistic (only depending on QtCore). Just like the gosmore and routino runner plugins it uses the new classes in src/lib/routing/instructions/. You'll notice some (intentional) duplication in the added code: Yet another point class and methods to calculate geodetic distances. This is needed to avoid the heavier GUI dependencies which would come in when using the Marble classes. This in turn imposes a problem on shared webservers.

There are two types of usage:

Online-Routing via some webserver (e.g. dev.osm.org)
PHP-Frontend => system ( gosmore | routing-instructions ) => KML => Marble => GeoDataDocument

Offline-Routing via the local system
Marble => QProcess( gosmore ) => Instruction generation => GeoDataDocument

The code used to generate the instructions itself isn't much magic: It parses a csv like format (waypoints and road names), groups them by road name to get the instruction points, calculates the angles between adjacent roads and generates human readable instructions from that information.

Testing
-------

A recent gosmore version from SVN (output with 6 fields and support for roundabouts, see screenshot)
An older gosmore version (the one shipped with Ubuntu Lucid, output with 5 fields, different .pak format)
Routino version 1.4.1
