Reduce maximum goroutine count

Running with the data race detector enabled hits a 8192 active
goroutine limit.  Reduce the maximum number of active goroutines
by limiting parallelVisit to 1000 goroutines.  Also rewrite
cloneModule in terms of parallelVisit.

Blueprint Build System

Build Status

Blueprint is a meta-build system that reads in Blueprints files that describe modules that need to be built, and produces a Ninja manifest describing the commands that need to be run and their dependencies. Where most build systems use built-in rules or a domain-specific language to describe the logic for converting module descriptions to build rules, Blueprint delegates this to per-project build logic written in Go. For large, heterogenous projects this allows the inherent complexity of the build logic to be maintained in a high-level language, while still allowing simple changes to individual modules by modifying easy to understand Blueprints files.
