Memoize full names of variables, pools and rules Variables, pools and rules each computed their full names every time they were referenced, which required string concatenations. Since every one is guaranteed to be accessed at least twice, once when the definition is written into the ninja file and once for each reference, precompute the full name. For local variables that can be done during initialization, but for global variables add a pass to PrepareBuildActions to compute the name for each live variable using the final package names. Test: ninja_writer_test.go Change-Id: I2264b05e0409e36651db2fb5d463c16c698d4d5e

Blueprint Build System
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.
