Make integrating with go tools easier by putting the blueprint package
files in the top level directory of the git project instead of in a
subdirectory called blueprint.

This change makes removeAbandonedFiles perform some of the string substitutions
that are done by the bootstrap script before considering whether a built target
still exists. It fixes a bug where the bootstrap manifest would get deleted
and subsequently regenerated, resulting in more re-bootstrap iterations than
was necessary.

This change makes the bootstrapping process remove any files that were
previously created by invoking a Ninja rule (i.e. they appear in the .ninja_log
file) but are no longer a build output target.

This change replaces the automatic caller package divination with a
PackageContext object that must be explicitly passed in by callers.

This change eliminates blueprint.ModuleType and replaces it with simple factory
functions. Rather than using the explicitly provided ModuleType names to
essentially identify the Go factory function in the generated Ninja files, we
now use the actual factory function name.

This change makes the bootstrap script take two optional flag-based command
line arguments rather than using positional arguments. The -i argument
replaces the old positional arguments (one of which was simply not needed), and
the -r flag now causes the script to regenerate the bootstrap Ninja file for
use when working on Blueprint itself.
Additionally this change allows all the configuration variables used in the
script to be overridden by environment variables. This makes it possible to
create a very simple bootstrap script for a customized Blueprint-based build
system by invoking this script after setting up the proper environment
variables.

This change adds a bunch of docs describing the bootstrap process. It also
renames a couple things in the source to better correspond with the terminology
used in the docs. On top of that it makes the standalone build to copy minibp
from the .bootstrap/bin directory to the bin directory to make it easier to
find.

This change causes the module and singleton content in generated Ninja files to
be sorted by name.
Change-Id: I6e1fe6d4211111c7dfa25ebe0fc721701a6d0256
This change fixes an issue where the re-bootstrapping process would overwrite a
newer bootstrap manifest with one that it generates using its older minibp. It
fixes the issue by only generating a new bootstrap manifest right after
rebuilding minibp (as part of the bootstrap process). It then uses an
additional rebootstrap iteration to replace the old bootstrap manifest with the
new one.

This change makes the module definition location that's included in the build
manifest comments use paths relative to the top-level source directory. This
should make the bootstrap build manifest not get regenerated when using a new
build directory.

Blueprint is a build system component that reads Blueprints files defining
modules to be built, and generates a Ninja build manifest that can be used to
perform all the build actions. It does not dictate or implement much build
policy itself, but rather provides a framework to ease the process of defining
build logic in Go.
The "blueprint" and "blueprint/parser" Go packages contain the functionality
for reading Blueprint files and invoking build logic functions defined in other
Go packages.
The "blueprint/bootstrap" Go package contains just enough build logic to build
a binary that includes Blueprint and any pure-Go (i.e. no cgo) build logic
defined in external Go packages. This can be used to create a minimal Ninja
file that's capable of bootstrapping a Blueprint-based build system from
source.
The "blueprint/bootstrap/minibp" Go package contains code for a minimal binary
that includes the build logic defined in the "blueprint/bootstrap" package.
This binary can then create the Ninja file for the bootstrapping process.
