The module name of system_$(VER) prebuilt file is system_sdk_v$(VER).
But this is inconsistent with sdk_v$(LOCAL_SDK_VERSION) in
prebuilts/sdk.
So, system_sdk_v$(VER) is changed to sdk_vsystem_$(VER) to use the same
naming policy.

-fsanitize=cfi requires LTO. Normally, the Clang driver automatically
enables emutls, but it's broken with -flto, so work around it by passing
-Wl,-plugin-opt=-emulated-tls.

See https://buganizer.corp.google.com/issues/72706604#comment15

Enable the workaround with ctx.Device(), which is the same condition used
in the existing I18acac41aac885fc6635fbd55f96ba7c845eb5e7 workaround.

core_current is a pseudo SDK version which is a core Java API subset of
the Android API. It is expected to be mainly used for external Java
projects which are agnostic to Android; such as junit, guava, etc.

A module built with this SDK version can only link to java modules of
the same kind. It can't depend on modules built with other sdk  (e.g.
current) or without sdk.

We were previously setting GOROOT to "prebuilts/go/linux-x86" during the
ninja executions when we were running Soong. But we can also run Soong
during the main ninja execution, were GOROOT was unset. When the GOROOT
was unset, the default GOROOT in our Go installation is
"./prebuilts/go/linux-x86" (note the extra ./).

This would cause g.bootstrap.goRoot to change between some soong runs,
causing us to rebuild all go programs (and anything depending on them)
more often than necessary.

So instead, keep GOROOT undefined when running Soong. Everything that
matters is using runtime.GOROOT(), which will fall back to the default.

Continue setting $GOROOT for bootstrap.bash, otherwise it fails when
there is no system provided go binary. What we give bootstrap.bash
doesn't really matter, since we don't actually use the blueprint wrapper
in Android.

Test: m blueprint_tools; touch bionic/libc/tzcode/new.c;
      m blueprint_tools <doesn't rebuild everything>

Change https://android-review.googlesource.com/c/572758, in addition to
dependencies from the compiler flags, also marked all exported
dependencies as implicit.  This can cause lots of unnecessary
recompiles.  This change moves exported dependencies back as order-only
dependencies.

Test: 1. mma in art after changing profile_compilation_info.h triggers
         only a limited number of recompiles.
      2. verify that changes to PGO profile files trigger recompiles.

This commit adds `extends: "name"` property and provides basic support
to VNDK extensions.  This is the simplest example:

```
cc_library {
    name: "libvndk",
    vendor_available: true,
    vndk {
        enabled: true,
    },
}

cc_library {
    name: "libvndk_ext",
    vendor: true,
    vndk: {
        enabled: true,
        extends: "libvndk",
    },
}
```

A vndk extension library must extend an existing vndk library which has
`vendor_available: true`.  These two libraries must have the same
`support_system_process` property.

VNDK-ext libraries are installed to `/vendor/lib[64]/vndk` and
VNDK-SP-ext libraries are installed to `/vendor/lib[64]/vndk-sp` by
default.

If there is a matching abi-dumps in `prebuilts/abi-dumps`,
`header-abi-diff` will be invoked to check for ABI breakages.
