How it works:
1. build/make/core/Makefile generates a txt file with the kernel
version, which is taken from an explicit BOARD_KERNEL_VERSION value,
or extracted from the kernel image on the source tree, or extracted
from the kernel image extracted from the prebuilt boot.img.
The file is saved at
$ANDROID_PRODUCT_OUT/obj/PACKAGING/check_vintf_all_intermediates/kernel_version.txt.
2. If PRODUCT_ENABLE_UFFD_GC is "default", meaning the GC type needs to
be determined by the kernel version, build/make/core/Makefile copies
kernel_version.txt to
out/soong/dexpreopt/kernel_version_for_uffd_gc.txt.
3. build/soong/dexpreopt/config.go writes the the UFFD GC flag to
out/soong/dexpreopt/uffd_gc_flag.txt. The flag is determined by an
explicit PRODUCT_ENABLE_UFFD_GC value or by contruct_uffd_gc_flag.py,
which reads kernel_version_for_uffd_gc.txt and determines the flag
accordingly.
4. dex2oat takes the UFFD GC flag from uffd_gc_flag.txt.
5. post_process_props.py mangles ro.dalvik.vm.enable_uffd_gc based on
the same logic.

This CL updates platform_systemserverclasspath,

prebuilt_systemserverclasspath_fragment to write entries for
STANDALONE_SYSTEMSERVER_JARS to systemserverclasspath.pb. A new property
`standalone_contents` is aded to `systemserverclasspath_fragment` and
`prebuilt_systemserverclasspath_fragment` to list the standalone system
server jars in the APEX, and entries will be written to
systemserverclasspath.pb accordingly at build time.
To add more context, these entries will be consumed by derive_classpath
in order to generate an environment variable
PRODUCT_STANDALONE_SYSTEM_SERVER_JARS. The environment variable will
then be comsumed by odrefresh to determine what jars to preopt on early
boot.
Note that the variable should not end with "CLASSPATH" because the list
is not used by runtime as a classpath. It is just a colon-separated list
of jars. System server loads the jars separately with paths hardcoded in
the code.

So add usesTargetFiles option and basePath option which indicates

This CL handles updatable boot jars in the same hacky way as we handle
non-updatable boot jars: it creates a set of predefined paths to the dex
jars in a global config, then traverses all modules in a singleton
context, finds updatable boot jars and adds copy rules from these jars
to the predefined paths. A proper way would be to register dependencies
of the dexpreopted modules on the boot jars and extracting paths to dex
files by walking these dependencies.

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".

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.

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).

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.

Previously default install path was provided only for comatibility
libraries that are added explicitly via `uses_libs`/`optional_uses_libs`

For some dependencies, like stubs, the SDK library may not be found at
build time (either because the implementation library is not among the
dependencies of the dexpreopted module, or because it's part of a
prebuilt, or because it's missing from the build altogether). In such
cases dexpreopt is useless, because dex2oat does not have access to the
full classpath (unless the &-classpath is used). Therefore do not
dexpreopt in such cases.
