f5e34b98ca Split "variant" terminology into "variant" and "variation"
"Variant" has been used to mean two slightly concepts in Blueprint.
The first and most obvious is a variant of a module, meaning a list
of all the ways that on version of a module differs from other
versions of the same modules, for example "arch:arm, link:static".
The other is for the specific way that a version of a module differs,
"arch:arm".

Rename all of uses of "variant" as the second meaning to "variation",
and update the documentation to clarify "variant" vs. "variation".
This modifies the build logic api to convert CreateVariants to
CreateVariations.

65569e4375 Add early mutators
The mutators that run after dependencies are resolved can be too late
to support build logic that needs to vary the dependencies based on
the mutated axis, for example architecture.  This patch provides an
EarlyMutator interface that can be used to mutate modules before
any dependencies have been resolved.

In order for dependencies to be satisifed in a later pass, all
dependencies of a module must either have an identical variant,
must have a single variant, or must be inserted using
DynamicDependencyModuleContext.AddVariantDependency.

ab6d790165 Move build actions into modules
Move actionDefs from moduleGroup to moduleInfo.  This will result
in multiple build.ninja headers for a single Blueprint file module
if it has multiple variants, each one specifying the variant
used to generate the following rules.

7addea35a1 Iterate through modules directly
Instead of iterating through groups and then iterating through the
group's modules, iterate through the modules directly.  This will
allow circular dependencies between groups as long as the individual
modules don't have circular dependencies.  In order to maintain the
ordering of modules in a group, each module is considered to have
an implicit dependency on any earlier modules in the same group.

e7daa22927 Rework the way variant names are stored
Replace the array of mutator name/variant name pairs with
a map of mutator name to variant name, and store the string
variant name separately.

ed342d983c Move values from moduleGroup to moduleInfo
Move most of the contents of moduleGroup into moduleInfo.  This will
eventually reduce moduleGroup to a simple list of variants of the
same module.

6134a5c66a Relax module naming restrictions
Forcing module names to be valid ninja names is an unnecessary
restraint on the project build logic.  Allow any string as a
module name, and sanitize and uniquify the module name for use
in module-scoped variables.

Also move the module scope to be per-module instead of per-group
so that modules can use the same local variable name for each variant.

10b54db7cc Fix panic when dependency cycle includes the first module visited
The cycle check can panic if the first call to check happens to land
on the first module in a cycle.  Print the cycle instead of panicking.

174ae059cc Report variant errors instead of panicing
Variant errors can be introduced by Blueprints files, so print
a module error instead of panicing.

8900e9bd37 Exit early from generateModuleBuildActions on error
generateModuleBuildActions was continuing to call GenerateBuildActions
on all modules even after one returned an error.  This could cause a
later module to panic because it was missing information that was
supposed to be generated by the module that returned an error, hiding
the earlier error message.

If a module returns an error, stop triggering any new goroutines to
call GenerateBuildActions on later modules.

3e8e74f276 Move blueprint/* up a directory
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.
