Before this change, exclude paths disabled sanitization of targets that
would otherwise be enabled by SanitizeDevice product variable (aka
SANITIZE_TARGET).
With this change, in addition to the above logic, exclude path disables
sanitization of targets that would otherwise be enabled by the
corresponding include path.
Effectively, this change disables sanitization of targets that are
covered by *both* include and exclude paths.

So far, when a library `libfoo` has `stubs.versions: ["10", "11"]`, then
`shared_libs: ["libfoo"]` is linked to the version 11 of the stub.
This requires the author of `libfoo` to manually update the property
whenever a new version is introduced. Otherwise, clients are not able
to use the newly added APIs because the latest stub is for an old
version.
This change eliminates the need for manual updating. "current" version
is always implicitly added to `stubs.versions`. It is added even when
nothing is set on the property, if `stubs.symbol_file` is set. i.e.
```
cc_library {
name: "libfoo",
stubs: {
symbol_file: "libfoo.map.txt",
// no versions: [...] needed
},
}
cc_library {
name: "a_client",
shared_libs: ["libfoo"],
apex_available: ["myapex"],
min_sdk_version: "29",
}
apex {
name: "myapex",
native_shared_libraries: ["a_client"],
min_sdk_version: "29",
}
```
`a_client` links to the "current" stub of `libfoo` that has all symbols
shown in the map file.
Note that, above doesn't mean that the client has unlimited access to
APIs that are introduced even after the min_sdk_version of the client
(29 in this example). The use of such APIs still has to be guarded with
`__builtin_available` check.

Test behavior was changed a while ago so that tests by default ignore
non-existent source paths (unless they explicitly check for/rely on
them). Prior to that CheckSnapshot() could detect when files were
missing from the snapshot but it no longer can.
This change disallows non-existent source files in all the sdk tests
which means that they are disallowed when processing the snapshots as
they use the same preparers as were used to process the sources.
This caused a test failure which has been temporarily ignored and has
a TODO and bug associated with it.

Background: `min_sdk_version` of a crt object is the oldest SDK version
that the crt object supports. When it's set to for example 16, Soong
creates a number of versioned variants of the crt object starting from
16 to the latest version. The variant for version X is provided to NDK
clients having `min_sdk_version` set to X.
Problem: all versioned variants of a crt object were built with `-target
<arch>-linux-android16`. Therefore they all have been with `#define __ANDROID_API__
16`. This is because the mutated variants still have the same
min_sdk_version property and the clang triple follows min_sdk_version,
not sdk_version. This is too conservative and against our intention to
provide the latest crt object that matches with the min_sdk_version of
the client.
In the other hand, the platform(non-sdk) variant of the crt object
doesn't have such a problem. min_sdk_version is completely ignored.
However, this is a bug and will be fixed by aosp/1640364. As a side
effect of the fixing, the platform variant will begin to built with a
very old __ANDROID_API__ which unnecessarily turns off the new platform
features like the TLS segment over-alignment.
This change fixes the problems:
* For the versioned variants of crt objects, we set both
`min_sdk_version` and `sdk_versio` to the version that the variant is
created for.
* For the platform variant of crt objects, `min_sdk_version` is force
reset to "current".

Background:
When compiling cc_* modules, min_sdk_version determines the "version"
part of the clang triple: -target <arch>-linux-android<version>. The
version part is used to make sure that calls to the APIs that are added
after the version are guarded with a runtime check (i.e.
__builtin_available).
Previously, min_sdk_version was used as the version part only when the
cc_* module is unbundled (e.g. built for an APEX or built with SDK). In
other words, min_sdk_version has been ignored for the platform variants.
They were built with the version number 10000.
This was problematic for Mainline module tests. Since they are neither
part of an APEX nor built with SDK (because they need to have access to
some of the module-only APIs), they are built with the version number
10000. As a side effect, __builtin_available macro are expanded to 1 at
build time - because 10000 is higher than any API versions. When such a
test built in the latest platform source tree runs on a device running
an old platform, it tries to call an API that might not be available on
the platform and experience a crash, due to the lack of the runtime
check.
This change fixes the problem by using min_sdk_version as the "version"
part of the clang triple, regardless of the module's variant. Then
__builtin_available macro in the tests doesn't expand to 1, but to a
function call to the libclang_rt.builtin library which checks the system
property ro.build.version.sdk.

__ANDROID_VNDK__ is defined for the modules that are able to use the
VNDK libraries. As both product and vendor variants define
__ANDROID_VNDK__, we don't know if a module is built for vendor or
product on build time.

specify the image-variant-dependent codes.

Restructures the cc package test setup code to create FixturePreparer
instances for setting up a test fixture and converts some tests to
use it.
The goal with this change is not to switch all the cc tests over to
directly using the new model but instead to ensure that the majority of
the cc tests run with the new model, to allow existing tests to easily
switch to the new model when needed and to allow dependent packages to
be switched to the new model.

Previously, a cc library that included .aidl, .proto and/or .sysprop
files and exported headers generated from at least one of those types
would actually export generated headers from all of them.
While headers generated from .sysprop files are always exported those
generated from .aidl or .proto should only be exported when explicitly
requested.
This change treats them separately as expected. It has the potential
to break the build as it could reduce the set of headers exported and
so a dependent module that needed those would break. The fix in that
case is to simply add one (or both) of the following to the module
that previously exported those headers:
aidl: {
export_aidl_headers: true,
}
proto: {
export_proto_headers: true,
}

When using the directed vendor snapshot, the build fails because soong
fails to find some variants of the modules that have been excluded
from VENDOR_SNAPSHOT_MODULES, even though those modules are not going
to be used by the build.
The solution implemented here is to generate fake versions of those
modules (empty files) and include them in the generated Android.bp,
so that soong finds the modules, even though trying to use them would
fail.

When a module has both 'product_specific: true' and
'vendor_available: true', the module does not have core variant but
have product and vendor variant modules. As the module generated
multiple variants, the names of the modules have the variant name
suffix. However, it did not create the module with the base module
name because it does not have core variant.
As the base module, in this case, is the product variant, use the
base module name for the product variant without adding the
'.product' suffix to it.
