344c4eeda9 java_sdk_library: Specify visibility of stubs modules
Adds two new properties to specify the visibility of the stubs modules
(source and library) created by the java_sdk_library. Excludes
visibility property from being inherited when creating the module so it
can be properly specified by copying across the relevant property.

c878250d3f java_sdk_library: Path extraction from deps depend on tag
Previously, the information that the java_sdk_library extracted from
its child dependencies was determined purely by the type of the
dependency and whether it had a tag of the appropriate type. The actual
tag itself was ignored. That worked but was a little fragile as it
relied on there being no overlap between the types of the dependencies
or if there was overlap on the order in which the dependencies were
processed and the dependency types were checked to ensure that the
correct information was collected.

This change makes the information that is extracted dependent on the
tag that is used. That makes the behavior much more robust and also
simplifes the follow up change which may get the stubs source and API
files from separate droidstubs invocations.

Changes:
* A func field is added to the scopeDependencyTag that is supplied with
  a dependency from which to extract the information and scopePaths
  into which the information will be stored.
* Each scopeDependencyTag instance supplies its own function.
* Various items are renamed to more closely reflect what they actually
  do. e.g. the apiFileTag is renamed to stubsSourceAndApiTag field
  because if provides access to both api file and stubs source.

6d7f0a719c java_sdk_library: Add support for module_lib API surface
Adds api scope for the module_lib and adds that to the list of all
all available scopes. The scope is generated if and only if the
api_surfaces property contains "module_lib".

No other changes are needed as the generation of the APIs is completely
driven by the allApiScopes array and the information in its contained
apiScope structures.

0d543640d5 Expand SystemApi annotation for generating system api
Metalava apparently normalizes the SystemApi annotation that was
previously used to the form that this change uses so this is
effectively a no-op. However, this does make this code more
self-consistent and also matches the form that is used in the framework
defaults for the mainline modules.

2aaef53b6d Switch java_sdk_library to use SetDefaultableHook()
Previously, java_sdk_library used AddLoadHook() to register a hook that
when called would create its child modules. That meant the
java_sdk_library properties that were used to create the child modules,
e.g. sdk_version could not be defaulted because the modules are created
before the defaults are applied.

This change switches java_sdk_library to use the new
SetDefaultableHook() mechanism to register the hook instead of the
AddLoadHook() mechanism.

It also prevents the child modules from being created if the module has
been disabled.

da36425419 java_sdk_library: Correct stubs source generation classpath
The stubs source should be generated using the same classpath that is

b8fa86ad6f Fix apex_available
Checking apex_available was missing some corner cases.
For example, the deps of share deps of cc_library modules are missed
while those from cc_library_shared are correctly tracked.

This was due to..

* calling DepIsInSameApex in WalkDeps: both work fine separately, but
when they are used together, it fails to work. It's due to how WalkDeps
works. (We might fix this bug too risky since it is used very widely)
* incorrect receiver for DepIsInSameApex in apex_deps mutator: receiver
is supposed to be parent, but child was used before. Interestingly lots
of deps are within the same group of module types(cc to cc, java to
java), it has worked. (note that receiver's DepIsInSameApex
implementation can be different).

This change fixes them by..

* walkPayloadDeps is now relying on ApexVariation, which is calculated
correctly by TopDown apex_deps mutator.
* use correct receiver for DepIsInSameApex in apex_deps mutator, which
requires for java.SdkLibrary to override the method and for
java.Library/Import to use passed dep instead of receiver to check its
membership of sdk.

implementation can be different).

This change fixes them by..

* walkPayloadDeps is now relying on ApexVariation, which is calculated
correctly by TopDown apex_deps mutator.
* use correct receiver for DepIsInSameApex in apex_deps mutator, which
requires for java.SdkLibrary to override the method and for
java.Library/Import to use passed dep instead of receiver to check its
membership of sdk.

e383388f98 Permissions XML file for java_sdk_library is mutated for APEX
This change fixes a regression that was introduced with
I597bccbb177b6b6320c3a3edeff467243230d384. With the change, the content
of the permissions XML file for a java_sdk_library was determined before
the java_sdk_library is mutated for an APEX. As a result, the file path
to the implementation jar library was always set to
/system/framework/*.jar regardless of whether the java_sdk_library is
part of an APEX or not.

This change fixes the problem, by creating the permissions XML file via
a new module type. The content of the xml file is determined after the
xml file is mutated for APEXes.

91b883d541 java_sdk_library - replace .docs suffix with .stubs.source
Previously, the .docs suffix was used for droidstubs internal modules
that generate the stubs source. The name was confusing so this change
replaces the suffix with .stubs.source to clarify the purpose of those
modules.

0bdcb27970 java_sdk_library_import - Allow it to replace java_sdk_library
Previously a java_sdk_library_import module did not replace the
corresponding java_sdk_library module, even when it was marked as
prefer=true. That is because the java_sdk_library_import had an empty
set of sources.	However, the stubs modules that are created by the
java_sdk_library_import did override the stubs modules created by the
corresponding java_sdk_library module.

That created inconsistent behavior between the cases where only the
prebuilt is available and both source and prebuilt are available and
the prebuilt is preferred. e.g. assume a java_sdk_library/import module
called SDKLIB.

When both prebuilt and source modules are available for SDKLIB then
even if the prebuilt is preferred then any dependencies on the
SDKLIB module would use the source module.

This change fixes that inconsisteny by making the array of sources
non-empty.

ab8da5dd53 java_sdk_library - pass patch_module through to stubs library
When building java.lang classes it is necessary to compile them using
patch_module: "java.base". This change causes patch_module to be passed
through to the java_library created to compile the stubs to allow this
to be used to generate stubs for java.lang.

e74ac73bc9 java_sdk_library - Allow it to be replaced by prebuilt
Previously, a java_sdk_library called "SDKLIB" would create a
prebuilt_etc module called "SDKLIB.xml" which installs the generated
XML permission file to /etc/permissions/SDKLIB.xml. That module
depended on the java_sdk_library "SDKLIB" to generate the XML file
as one of its outputs by specifying srcs: [":SDKLIB{.xml}"].

If the java_sdk_library is replaced by a prebuilt then the SDKLIB.xml
module expects the prebuilt to provide the XML permissions file which
it doesn't because that is an implementation detail and so the build
breaks.

A couple of alternative approaches were looked at to fix this. One was
to have the logic that replaced the source module with the prebuilt to
inform the source module that it was being replaced so it could disable
its created module. That lead to a dependency cycle where
    SDKLIB -> SDKLIB.xml -> SDKLIB{.xml}

Another solution was to mark dependency tags in such a way that the
prebuilt could automatically identify and disable the SDKLIB.xml
module. Similar to how the visibility code will ignore dependencies
that are tagged with ExcludeFromVisibilityEnforcementTag. That became
very convoluted.

Instead the java_sdk_library was changed so that it was not responsible
for creating the XML permissions file. Instead it created a genrule
called "gen-SDKLIB.xml" to create it and then "SDKLIB.xml" depended on
that. The java_sdk_library also depended on the genrule to make the XML
permissions file available for APEX and testing.

Some refactoring of the APEX code and tests was necessary because they
had knowledge of the internal implementation of java_sdk_library. The
refactoring insulates them a little better from those details.

50061511d4 java_sdk_library - Use prebuilt/prefer for unbundled app builds
Previously, the java_sdk_library had special support for disabling the
stubs library when the build was configured to use prebuilts for sdks,
e.g. in an unbundled app build. That caused the prebuilt version of the
stubs library to be used instead. The disabling was done irrespective
of whether a prebuilt was available which prevents java_sdk_library
from being used in situations when prebuilts are not available, e.g.
when they have not been created yet.

This change moves the logic into tha java_sdk_library_import and
leverages the existing prebuilt/prefer mechanism to ensure that the
prebuilt version is used when required.

* Adds a ForcePrefer() method to Prebuilt to allow a module to forcibly
  set the value of the prefer property.
* Sets prefer true on the java_sdk_library_import and the stubs modules
  it creates when the prebuilt version should be used.
* Refactors PrebuiltJars for use by both java_sdk_library and
  java_sdk_library_import as they both need to provide access to
  prebuilts for previously released versions of the library.
* Removes disabling logic from java_sdk_library.

This will probably require some additional java_sdk_library_import
modules to be added to prebuilts/sdk/current/Android.bp.
