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.

Context.ModulePath is a duplicate of Context.BlueprintFile, and is
misleading because it returns the path to the Android.bp, and not
the path to the directory that contains the Android.bp file like
ModuleContext.ModuleDir.

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.
Previously a LoadHook could not modify the name of a module because the
module was registered before the LoadHooks were run. That made it very
complicated (requiring mutators and auto generated names) to create a
module type whose name was determined by say the directory in which it
is defined.
This change moves the LoadHook execution slightly earlier so it runs
before registration of the module.
That caused one slight side problem which was that the
moduleInfo.Name() would fail when called in a LoadHook. That was
because that gets the name from group.name but was group was nil
because it is only set when the module is registered.
Modifying the moduleInfo.Name() method to get the name from the module
logicModule.Name() if group is nil fixed that. The reason for getting
the name from the group.name rather than the logicModule.Name() is that
the former tracks renames but the latter does not. However that is not
an issue in this case as there has been no opportunity for the module
to be renamed until after the LoadHook has returned.
Previously, WalkDeps() would record that a module was visited after the
first time it encountered the module irrespective of whether it recursed
into or not. This change moves the recording so it happens only after it
has been recursed into.
Added TestWalkDepsDuplicates_IgnoreFirstPath to test the change. Without
the change the test fails because it does not visit E.
Test refactoring:
* A depsMutator was added instead of relying on blueprintDepsMutator to
allow different tags to be used for different dependency types.
* Modified barModule and fooModule to support the new depsMutator and
add support for another type of dependency that is ignored by the
walking code.
* Extracted walkDependencyGraph() function to reuse common code.
Mutators were not propagating the results of ctx.AddNinjaFileDeps.

There are 8935901 *ninjaString objects generated in an AOSP
aosp_blueline-userdebug build, and 7865180 of those are a literal
string with no ninja variables.
Each of those *ninjaString objects takes a minimum of 48 bytes for
2 slices, plus 8 bytes for the pointer to the ninjaString. For
the literal string case, one of those slices has a single element,
(costing another 16 bytes for the backing array), and the other
slice is empty, for a total of 72 bytes.
Replace *ninjaString with a ninjaString interface. This increases
the size of the reference from 8 bytes to 16 bytes, but using
a type alias of a string for the literal string implementation uses
only 16 bytes, saving 40 bytes per literal string or 314 MB.

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.

This fixes a bug that reverse dependency can't be made for modules
having local variations. Previously, when module A having local variants
calls AddReverseDependency to module B having local variants, the match
is tested between the non-local variants of module A against all
variants of module B, which can never be successful.
This change fixes it by using all variants of module A when
findMatchingVariants is called for AddReverseDependency.

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.

Writing the ninja file to a byte buffer causes a significant amount

Instead of sometimes re-running minibp/the primary builder during the
next phase, run bpglob earlier to check dependencies.
We've run into issues where the environment is slightly different
between bootstrapping phase and the main build phase. It's also a
problem because our primary builder (Soong) exports information used by
another tool (Kati) that runs in between the bootstrapping phases and
the main phase. When Soong would run in the main phase, it could get out
of sync, and would require the build to be run again.
To do this, add a "subninja" include a build-globs.ninja file to each
build.ninja file. The first time, this will be an empty file, but we'll
always run minibp / the primary builder anyway. When the builder runs,
in addition to writing a dependency file, write out the
build-globs.ninja file with the rules to run bpglob.
Since bpglob may need to be run very early, before it would normally be
built, build it with microfactory.
