Replace XML parser with pbfparser

[zod]

As explained in #468 BRouter currently has two parsers

• "XML" Parser (doesn't really use a XML library and rejects valid XML) which should be only used for testing but is integrated into the build
• PbfParser which is used in production but requires manual download of osmosis and building

We should just use PbfParser and remove the "XML" parser. This adds a dependency on osmosis/protobuf, but the JAR file size only slightly increased to 2.2 MB. I think this slight increase is worth avoiding the building hassle.

PbfParser has an optimization which polls its input file to allow reading a pbf file while update from osmupdate is still in progress. For small files (e.g. when testing) this causes a delay of at least two minutes, therefore it's now configurable using avoidMapPolling (e.g. java -davoidMapPolling=true).

Fixes #468
