Previously, the only way for a module type to create modules (other
than defining its own mutator) was to register a LoadHook. However,
that is called before defaults are applied so any properties used in
that hook cannot take advantage of defaults, e.g. java_sdk_library
cannot use defaults to set its sdk_version property and have that
affect its child modules.
This change adds a new SetDefaultableHook() to DefaultableModule to
register a hook that is called after any defaults have been applied.
Also adds some tests to ensure that errors in the visibility property
introduced in a DefaultableHook are reported in the gather phase of
visibility processing.
A follow up change will switch java_sdk_library to use that instead
of the AddLoadHook() mechanism.

Adds a couple of new methods to manage visibility property instances to
reduce duplication and encapsulate the implementation slightly better.
The AddVisibilityProperty method is exported as it will be needed by
other packages in follow up commits.

Product variables structs are generated at runtime to contain only
the properties that apply to the current module. Defaults modules
always contained all product variable properties. Defaults modules
apply their properties to the target module using
proptools.PrependProperties, which prepends structs that have
matching types. Filtered property structs had a different type
and were dropped.
Even after adding filtering to the defaults product variable
properties, defaults modules may contain more property structs
than the target module they are applied to, so the product
variables struct for the defaults module could contain more
fields than the product variables struct for the target module.
Use proptools.PrependMatchingProperties when applying defaults
of product variables instead, which will apply matching properties
across types.

Existing modules, either general one or package ones have a single
visibility property, called visibility in general, and
default_visibility on package, that controls access to that module, or
in the case of package sets the default visibility of all modules in
that package. The property is checked and gathered during the similarly
named phases of visibility processing.
The defaults module will be different as it will have two properties.
The first, visibility, will not affect the visibility of the module, it
only affects the visibility of modules that 'extend' the defaults. So,
it will need checking but not parsing. The second property,
defaults_visibility, will affect the visibility of the module and so
will need both checking and parsing.
The current implementation does not handle those cases because:
1) It does not differentiate between the property that affects the
module and those that do not. It checks and gathers all of them with
the last property gathered overriding the rules for the previous
properties.
2) It relies on overriding methods in MethodBase in order to change the
default behavior for the package module. That works because
packageModule embeds ModuleBase but will not work for
DefaultsModuleBase as it does not embed ModuleBase and instead is
embedded alongside it so attempting to override a method in
MethodBase leads to ambiguity.
This change addresses the issues as follows:
1) It adds a new visibility() []string method to get access to the
primary visibility rules, i.e. the ones that affect the module.
2) It adds two fields, 'visibilityPropertyInfo []visibilityProperty'
to provide information about all the properties that need checking,
and 'primaryVisibilityProperty visibilityProperty' to specify the
property that affects the module.
The PackageFactory() and InitAndroidModule(Module) functions are
modified to initialize the fields. The override of the
visibilityProperties() method for packageModule is removed and the
default implementations of visibilityProperties() and visibility()
on ModuleBase return information from the two new fields.
The InitDefaultsModule is updated to also initialize the two new
fields. It uses nil for primaryVisibilityProperty for now but that
will be changed to return defaults_visibility. It also uses the
commonProperties structure created for the defaults directly instead
of having to search for it through properties().
Changed the visibilityProperty to take a pointer to the property that
can be used to retrieve the value rather than a lambda function.

Blueprint allows multiple dependencies on the same module after
https://github.com/google/blueprint/pull/210.
Fix defaults, WalkDeps can now find the same defaults module multiple
times.
Fix droiddoc, if the srcs_lib points to a lib module that is
specified multiple times, for example through explicit properties
and implicit default libraries, the srcs would be listed on the
command line multiple times. Move srcs_lib to use its own dependency
tag.

Fix mutator registration for tests to allow different tests
in the same package to register different mutators.
Allow tests to track the resulting ModuleBuildParams objects
to use in assertions, and provide helpers for getting them.
For example:
config := android.TestConfig(buildDir)
ctx := android.NewTestContext()
ctx.RegisterModuleType(...)
ctx.MockFileSystem(...)
ctx.ParseBlueprintsFile("Android.bp")
ctx.PrepareBuildActions(config)
ctx.Register()
// Get the Inputs value passed to the javac rule for the foo module
inputs := ctx.ModuleForTests("foo".Rule("javac").Inputs
