f5d91bb3b4 Revert "Don't add uses_libs/optional_uses_libs to the manifest_fixer."
This reverts commit 0b1c70efbc.

The reverted commit was based on the idea that uses-libraries that are
explicitly specified in build files should not be implicitly added to
the manifest, as that would mean that anything added to the build files
will flow to the manifest.

Although this logic is correct, it prevents propagation of
uses-libraries from dependencies, which is wrong: if a library has an
explicit uses-library property in Android.bp, this property is expected
to be propagated to the library's dependencies. Failing to do so would
mean that every user of that library has to add uses-library property to
their build files, which doesn't scale (see b/214255490 for example).

91f015e73e Correctly serialize class loader context for "any" SDK version to JSON.
Previously "any" was serialized as its numeric value, 10000. But other
code in makefiles and scripts expects string "any", and dexpreopt.config
files generated by Make (for Android.mk modules) have "any" not 10000.

0653057603 Add support for excluding libraries from class loader contexts
A number of tests in the cts/tests/signature/api-check check for the
accessibility of classes from the android.test.base,
android.test.runner and android.test.mock libraries. Some tests expect
to find the classes other do not. Unfortunately, the tests use
libraries, specifically compatibility-device-util-axt, that depend on
the android.test... libraries which causes Soong to implicitly add
<uses-library> entries to the manifest so that they will be accessible
at runtime. That causes the tests that do not expect to find the
classes to fail.

7b6a55f5a2 Fix OutDir vs SoongOutDir in tests
Tests were using the same value for OutDir and SoongOutDir, separate
them to allow a test that needs to distinguish between them.

0b1c70efbc Don't add uses_libs/optional_uses_libs to the manifest_fixer.
These properties specify libraries that cannot be implicitly inferred by
Soong. If these properties are added to Android.bp, this can only be for
the reason that there is a <uses-library> tag in the manifest which is
unknown to the build system. Adding them to the manifest_fixer doesn't
make sense: if they are not in the manifest, they should be removed from
Android.bp as well.

fc0f6e34ce Fix the way manifest fixer detects optional <uses-library> entries.
Previously manifest_fixer used a naive way to distiniguish optional libs
from required ones: it checked if a library is on the list of optional
compatibility libraries. This works for compatibility libs, but not for
other libs.

Now we properly track optionality through all stages of the build,
starting with the addition of the library as a dependency (here's where
the `uses_libs`/`optional_uses_libs` distinction kicks in), store it in
dependency tag and propagate to class loader context, and from there to
the manifest_fixer.

The tests have been updated accordingly.

7bc1cf508f Remove obsolete class loader context API and update unit tests.
The removed API has been unused since https://r.android.com/1533342
(except for unit tests).

Changes in the unit tests reflect the change of API in
https://r.android.com/1533342: early errors caused by unknown library
paths at CLC construction time have been replaced with late errors at
the time of CLC validation.

78a7155c17 Assume any <uses-library> is shared, add only toplevel ones to manifest.
This patch reworks the approach introduced in
https://r.android.com/1450819. That patch based the decision which
libraries should be added to the manifest <uses-library> tags by the
manifest_fixer on the "shared" status of the library.

That approach is incorrect for two reasons:

  - It doesn't make sense to have a non-shared library in class loader
    context ("shared" libraries are those specified in
    frameworks/base/data/etc/platform.xml, and they are the only ones
    that PackageManager knows about).

  - It doesn't make sense to add anything but the top-level of the
    class loader context tree to the manifest, because this part of the
    tree is flattened to a sequence, and PackageManager cannot restore
    it to the previous tree shape (there is an information loss).

This patch removes the "shared" bit of information from class loader
context elements and assumes that all libraries that end up in class
loader context are shared. Consequently, only the top-level libraries
should be passed to manifest_fixer.

18554243de Add nested class loader subcontext at the proper hierarchy level.
When adding a subcontext in a class loader context tree, there are two
possible cases: 1) the root of the subcontext is itself a <uses-library>
and should be present as a node in the tree, or 2) the root is not a
<uses-library>, but some of its dependencies are -- in that case they
should be disconnected from the root, and the resulting forrest should
be added at the top-level.

Example:

  1) C is a <uses-library>:

     A
     ├── B
     └── C
         ├── D
         └── E
             └── F

  2) C is not a <uses-library>:

     A
     ├── B
     ├── D
     └── E
         └── F

Before the patch subcontexts for transitive dependencies were added
before the subcontext for the direct dependency (even if it was a
<uses-library>, resulting in case-2 hierarchy when case-1 should have
been used. Previosuly this didn't matter because class loader context
was a flat set of libraries, but now it matters because class loader
context is a tree.

This patch changes the order in which libraries are added, so that
direct dependencies are added before transitive ones. The context adding
method now accepts an "implicit root" parameter, so that when adding
transitive dependencies it can check if the corresponding direct
dependency is a <uses-library> and already present in the context.

Partially constructed class loader context is now propagated top-down
into aapt.buildActions, so that the method can use existing part of the
context to decide where the missing part should be connected.

5e13a7307e Disallow adding nested conditional class loader context.
Nested conditional context doesn't make sense because conditional
context is only needed for compatibility libraries, and those are only
used by apps, and apps are always at the root of class loader context
tree. Therefore, trying to add conditional nested context can only mean
an error somewhere on the way.

8cbc5d269b Rework class loader context implementation.
The old representation consisted of a list of libraries (UsesLibraries),
a list of optional libraries (OptionalUsesLibraries) and a mapping from
library name to its build/install paths (LibraryPaths). The separation
into lists and map was necessary because of special handling of
compatibility libraries, which is now unified with normal libraries.

The new representation is a mapping from target SDK version to a tree
structure ClassLoaderContext. Each node of the tree represents a library
and contains library name, build/install paths and a slice of
subcontexts for dependencies. The same library may occur in the tree
multiple times in case it is a dependency of multiple libraries. The
order in which libraries are added matters (the resulting tree shape may
be different).

Test results have to be updated, as the resulting <uses-library> list is
reodered (previously it was a sorted list of map keys, and now it is
formed by a depth-first preorder traversal of the class loader tree).
