Previously there were two different scripts that did similar things:
1) build/soong/scripts/manifest_check.py
2) build/make/core/verify_uses_libraries.sh
Both scripts extracted <uses-library> tags and `targetSdkVersion` from
the manifests of Java modules, but 1) worked for XML manifests, and 2)
worked for APKs. This CL reimplements the functionality from 2) in 1),
so that one script can handle both XML manifests and APKs.

In cases when class loader context cannot be computed at build time and
verify_uses_libraries check is relaxed (RELAX_USES_LIBRARY_CHECK=true)
dexpreopt uses a special compiler filter that suppresses AOT-compilation
to native code and applies only those optimizations that do not require
class loader context. Previously the "extract" filter was used. Now ART
supports using "verify" filter in this configuration.

The new mode is enabled with environment variable
RELAX_USES_LIBRARY_CHECK. If the variable is set to true, then a
verify_uses_libraries check failure does not fail the build, instead it
sets a special compiler filter "extract" for dexpreopt, which means that
the DEX file will be extracted, but it won't be compiled to native code.
Class loader context will be set to empty in this case (not &, as it is
going to be deprecated soon).
If the variable RELAX_USES_LIBRARY_CHECK is unset or set to something
other than "true", then the old behaviour of the verify_uses_libraries
check is preserved.
The intended use case for this flag is to have a smoother migration path
for the Java modules that need to add <uses-library> information in
the build files. The flag allows to quickly silence build errors. This
flag should be used with caution and only as a temporary measure, as it
masks real errors and affects performance.
verify_uses_libraries check is reworked so that it writes the error
message to a status file (which is used instead of the former timestamp
file). Currently the stored error message is not used, but it may be
used later to produce a warning. Dexpreopt command checks if the status
file exists and is nonempty; if that is the case, then compiler filter
is set to "extract".

Library order is important because it is used to construct class loader
context, which is then written into OAT/ODEX files and chacked against
class loader context constructed by PackageManager on the device. If the
orders are different, dexpreopted code is rejected.
Soong avoids using Go maps for class loader context representation
precisely for that reason. However, for the modules defined in makefiles
dexpreopt configs were serialized to JSON and unmarshaled to Go maps,
which resulted in wrong order of libraries. This CL changes Go
representation of class loader contexts imported from JSON and makes the
order stable.

This is needed for Java libraries that are <uses-library> dependencies
of Java libraries and apps defined as Make modules. Each dexpreopted
module in Make generates a dexpreopt.config file, which incorporates
information from its dependencies' dexpreopt.config files. For
dependencies that are Make modules their dexpreopt.config files are
generated by Make, and for Soong modules they are generated by Soong.
Since Soong doesn't know which libraries are used by Make, it generates
build rules for a superset of the necessary libraries.

Previously, the createGlobalSoongConfig() function was explicitly
prevented from being used in tests because it would fail. However, it
turns out that is no longer the case and it does now work.
That allows the following changes to be made:
* Tests no longer need to use GlobalSoongConfigForTests() to
prepopulate the cache.
* GlobalSoongConfigForTests() is only needed in the dexpreopt
package.

Previously CLC construction was scattered across different module types
and dependency tags. This CL moves all logic to one function, which
handles all special cases. This will allow to simplify CLC API and
reduce the number of different ways in which CLC is constructed.
Previously some of the cases failed early (at the time when a library is
added to CLC) if the build/install paths were unknown. Other cases did
not fail early, but were validated later before CLC was used. Late
failures are necessary because some of the libraries with unknown paths
still have to be processed by manifest_fixer (which doesn't need library
paths), but they do not use dexpreopt (which needs library paths). This
CL removes the early failures (all paths are still validated later).
The CLC tests do not fail because they use a private method that toggles
the "strict" flag (that enforces early/late failure mode) manually in
the method call.
The CL also makes a functional change in the way CLC is constructed for
component libraries that have an OptionalImplicitSdkLibrary(), or
libraries that are disguised as SDK libraries via `provides_uses_lib`.
Previously such a component/disguised library X was added to its own CLC
as a sibling element of X's own <uses-library> dependencies, which
created incorrect CLC structure. Now this is handled by addCLCFromDep,
when X is processed as dependency and added as a top-level CLC element
with its sub-CLC properly nested under it.

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.

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.

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

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).

construct_context.py is a script that runs at Ninja stage and constructs
class loader context arguments for dex2oat. Previously it accepted lists
of library paths and concatenated them into one class loader context
string. The script also handled the dependency of "android.hidl.manager"
on "android.hidl.base" that is not tracked by the build system and must
be handled in a special way.
Now that class loader context representation is going to change from
flat lists to trees, passing paths to individual libraries as script
arguments is no longer possible, because a list of paths cannot
represent a class loader context tree. Passing the trees in a serialized
form is also inconvenient, because the script would have to parse them,
which would complicate it a lot.
Therefore this patch ports all the concatenation and "android.hidl.base"
handling to Soong. It is not possible to port the remaining script to
Soong because Soong has no information about the targetSdkVersiion of
the dexpreopted apps (it is in the manifest and sometimes in an APK, and
has to be extracted at Ninja time).

Also, add tests for compatibility libraries in class loader context.
This CL separates special-case handling of compatibility libraries into
a "fixup" step that is done after class loader context is constructed by
Soong. This allows to handle compatibility libraries and normal
libraries uniformly, which should enable further simplification of class
loader context representation (in subsequent CLs).
Currently the only "fixup" step is removal of libraries from conditional
class loader context if they already are in unconditional context. This
check cannot be done at the time when the libraries are added to
conditional context, because the full uncoditional context is not yet
known at that time. Previously construction of unconditional context was
delayed, now it is no longer delayed and handled in the same way as
unconditional context, and the "fixup" does the filtering.

This doesn't apply to compatibility libraries (those added to
conditional class loader context base on the targetSdkVersion in the
manifest), because Soong doesn't know if they are needed or not (the
build rule that parses the manifest runs at Ninja stage).
In the future we may need to relax this and instead of failing the build
to disable dexpreopt in such cases. But currently there are no use cases
that fail.

Previously, the patterns in SYSTEM_OTHER_ODEX_FILTER only matched
subpaths of /system. Broaden this to match /<p> as well as /system/<p>.
Because SYSTEM_OTHER_ODEX_FILTER includes system_ext and product apps,
the immediate effect of this is that the odex and vdex files of
apps on those partitions move to system_other for A/B devices.
This makes the product and system_ext partitions smaller, which
in turn makes OTAs smaller.
