Providers are a new concept for Blueprint, based on providers in Bazel:
https://docs.bazel.build/versions/master/skylark/rules.html#providers
Providers aim to simplify the interaction between modules by replacing
type asserting to arbitrary interfaces with requesting optional data
objects from modules. This will also move Blueprint closer to supporting
incremental analysis by serializing the providers and only rerunning
the analysis phase on modules whose inputs have changed.
Change-Id: I39f5f78b372412a7dbf151ceccb3f917f6c874bf
The motivaion for this change is to allow writing code that uses the
newly added dependency module in the same mutator pass, for example to
add more dependencies. Like this:
for _, m := range ctx.AddVariationDependencies(nil, tag, deps...) {
if someModuleProperty(m); ok {
ctx.AddVariationDependencies(nil, tag, otherDep)
}
}
Note that there is no guarantee that the returned module has already
been processed by the current mutator.
The patch does not add runtime overhead on findng dependency modules,
as this has already been done previously.

AddFarVariationDependencies takes the first matching variant. To

CreateAliasVariation creates a new variation for the current mutator
that is an alias to a variation that was created with CreateVarations
by the same mutator. It is similar to AliasVariation, except that
AliasVariation creates an alias from the pre-mutated variant to one
of the new variations, while CreateAliasVariation creates an alias
from a new post-mutated variation to one of the new variations.

Adds a CheckBlueprintSyntax(...) method to check the syntax of a
Blueprint file.
Changes processModuleDef and newModule from being method on *Context to
being standalone functions. That ensures that CheckBlueprintSyntax(...)
does not need to take a context and so there is no chance that it can
change its state.
Add RegisterScopedModuleType to LoadHookContext that registers
a module type factory that will be visible for the remainder of

Adding a dependency on a module with variants can be problematic
if the code adding the dependency is not aware of every mutator
that has created variants. Add an AliasVariations to
BottomUpMutatorContext, which allows a mutator to alias the
original variant of a module to one of the new variants of the
module, which will allow future dependencies to be added using
the original list of variations. The aliases are transient,
and only exist until the next mutator that calls CreateVariations
when visiting the module without also calling AliasVariations.

Modules are created with a nil variantionMap, which avoids allocating
an empty map if the module will never be split.
Context.addVariationDependencies constructs a variationMap to
compare against the variationMap of each variant, but constructed
an empty variationMap if no variations were specified. A nil
map is not the same as an empty map, so consistently use a nil
map and create it when populating the first entry.

SetDefaultDependencyVariation sets the variation name that will be used
when a dangling dependency is found while a module is being split. A
dangling dependency can occur if a module is split to a variant that one
of its dependencies is not split into. When the default variation is not
set, such dangling dependency is a hard error. But with the new
function, the default variation can be set and subsequent calls to
CreateVariations and its variations on the same context uses the default
variation when necessary.
(If even the default variation does not exist for the dependent module,
it is an hard error)
Note that this is different from calling SetDependencyVariation("foo")
followed by CreateVariations("foo", "bar"). In that case, regardless of
whether a dependency of the current module has the variant 'bar' or not,
only the 'foo' variant is chosen.
With SetDefaultDependencyVariation("foo") followed by
CreateVariations("foo", "bar"), 'foo' variant is used only when the
'bar' variant of the current module depends on a module that does not
have 'bar' variant.

Move most of the mutator context methods into BaseModuleContext
so they are available to both top down and bottom up mutators.
Only CreateModule is unique to TopDownMutatorContext, and the
dependency and variation adding methods are unique to the
BottomUpMutatorContext.
The dependency visiting methods are now available on
BottomUpMutatorContext, which requires delaying making newly
added dependencies visible to maintain the invariant that
the mutator has been called on the dependency before the
dependency can be visited by its parents.

WalkDeps was following every possible path through the dependency

Mutator context goroutines appending directly to the global Context's
replacements list causes a data race. Send them over a channel
instead.
The renames and replacements are local to the mutator, so move them
out of Context and into the runMutator method.

Add globbing with dependency checking to blueprint. Calling
ModuleContext.GlobWithDeps or SingletonContext.GlobWithDeps will return
a list of files that match the globs, while also adding efficient
dependencies to rerun the primary builder if a file that matches the
glob is added or removed.
Also use the globbing support for optional_subdirs=, subdirs= and build=
lines in blueprints files. The globbing slightly changes the behavior
of subname= lines, it no longer falls back to looking for a file called
"Blueprints". Blueprint files that need to include a subdirectory with
a different name can use build= instead of subdir= to directly include
them. The Blueprints file is updated to reset subname="Blueprints" in
case we want to include subdirectories inside blueprint and the primary
builder has changed the subname.
Also adds a new test directory that contains a simple primary builder
tree to test regeneration for globbing, and runs the tests in travis.

Allow modules to be renamed by mutators. This will allow modules to
dynamically adapt to the presence or absence of modules with the same

could rename itself to the name of the source module so that
dependenices on the module name are satisified.
