Running with the data race detector enabled hits a 8192 active
goroutine limit. Reduce the maximum number of active goroutines
by limiting parallelVisit to 1000 goroutines. Also rewrite
cloneModule in terms of parallelVisit.

This makes it easy for users of Glob to detect whether the match is a
file or directory. Doing the check at this level means that the filelist
file used as a dependency will be updated if a directory is replaced
with a file of the same name, or vice versa.

PreSingletons use the same interface as Singletons, but run after
parsing all the blueprint files but before running any mutators
or GenerateBuildActions. They can be used to perform global setup,
including generating rules, that may be referenced by later
mutator or generate passes.

Allow a module to create other modules as if they were specified

calls the factory function the module type, and then inserts

This still isn't the best experience for users, but it at least provides
enough information for someone more familiar with the build to
understand the problem.
It is not allowed to directly use BaseDependencyTag as customized
user dependency tag passed down to BP since it might cause issues
that different type of modules will be mixed when fetched based on
Tag.
Add globbing to filesystem mocking so that more code can be tested

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.

Bypassing c.glob() and using filepath.Glob() directly for non-glob
paths does not add dependencies on directories that contain missing
files. For optional_subdirs, this means no dependency is added to
rerun the primary builder when an Android.bp file is added to an
optional_subdirs directory. Always use c.glob(), for the non-optional
case it will not insert any dependencies if the file exists (as tested
by glob_test.go's no-wild tests), and if the file doesn't exist the
len(matches) == 0 will error out.
Change-Id: I370479c6e89f5ff590897702e256256a4dca6952
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
name. For example, if a source module does not exist, a prebuilt module
could rename itself to the name of the source module so that
dependenices on the module name are satisified.

Don't add a "_" to the variant name if the variation name is empty. For

"bar", the new variants would be named "foo" and "foo_bar" instead of
"foo_" and "foo_bar".

Convert parallelVisitAllBottomUp into a generic parallelVisit that takes

function pointer in the mutatorInfo to run. Optimize out the
updateDependencies to only run if dependencies have been modified to
avoid running it after TopDownMutators that cannot modify dependencies.
