Write build definitions directly to output writer buildDef.WriteTo was calling valueList to convert all the build parameter ninjaStrings into strings, which uses ValueWithEscaper to build a strings.Builder. This results in building a string only to immediately copy it into the output writer's buffer. Instead, pass an io.StringWriter to ValueWithEscaper so it can build the string directly into the output writer's buffer. This requires converting ninjaWriterWithWrap into an io.StringWriter. Test: ninja_writer_test.go Change-Id: I02e1cf8259306267b9d2d0ebe8c81e13dd443725

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.
