Concurrent filepath.Walk replacement

A concurrent version of filepath.Walk function that scans files in a directory tree and runs a callback for each file.

Since scanning (and callback execution) is done from within goroutines, this may result in a significant performance boost on multicore systems in cases when the bottleneck is the CPU, not the I/O.

Upstream tests showed ~3.5x average speed increase on an 8-core CPU and 8 workers. For measurements, upstream used provided bin/traversaltime.go utility that measures directory traversal time for both concurrent (cwalk.Walk()) and standard (filepath.Walk()) functions.
