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.

VariableConfigMethod creates a Ninja variable whose value comes directly from a
method on the config object.

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.
