22603	[PATCH] Add PBF reading support to JOSM	taylor.smock	taylor.smock	"This is a followup of #6886.

Major differences:
* It uses the JOSM Protobuf parsing code instead of Google's Protobuf parser
* It is ''not'' based off of any of the code from https://github.com/openstreetmap/OSM-binary ''except for the proto files''. I'm unsure what the licensing situation would require.
* ~1500 added lines
* Performance for PBF reading when compared against the PBF plugin
 * [http://download.geofabrik.de/north-america/us/colorado-latest.osm.pbf colorado-latest.osm.pbf] was used for profiling. Note: Takes ~8.8 GB of memory to load the file, no clue how much is needed to ''render'' it.
 * PBF plugin (max memory in use: 8779 MB):
  * Time spent loading PBF: 49.5s (3 runs with same time spent)
  * Memory allocations: 30,155,126,741 (average across three runs, ~500 MB spread)
  * CPU cyles: 3061 (average across 3 runs, ~600 CPU cycle spread)
 * Patch (max memory in use: 8783 MB):
  * Time spent loading PBF: 75s (average across 3 runs, min 62s, max 89s)
  * Memory allocations: 30,098,125,773 (average across three runs, ~900 MB spread)
  * CPU cyles: 4650 (average across 3 runs, min 3862, max 5356)"	defect	closed	normal	23.03	Core		fixed	pbf
