Merge remote-tracking branch 'aosp/upstream' into master

* aosp/upstream:
  prevent file=nil panic if syntax error in Blueprints
  have openAndParse use return values rather than channels
  rename parseOneAsync to openAndParse
  Update microfactory compile error message to show the command that failed

Test: see tests on individual commits

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.
