[osmosis-dev] Support for reading and writing PBF files to/from STDIN, STDOUT, or named pipes.

[Scott Crosby]

My fork of osmosis at  https://github.com/scrosby/osmosis   supports
reading and writing PBF files from pipes. You can access this by
either using named pipes or by using the magic filename '-' to denote
STDIN/STDOUT.

Please test this functionality and report any problems.
