a0790e35c7 Rework how linux_bionic is built with LLD
In order to simplify the wrapper function, and stop using a linker
script, generate a set of flags to pass to LLD. Then run
host_bionic_inject on the linked binary in order to verify the
embedding, and give the wrapper function the address of the original
entry point (_start).

ff1458f670 APEX can be signed with different keys
A new module type 'apex_key' is defined to specify public and private
key pair for APEXs. An APEX can refer to the module via the property
'key'. When building the APEX, the private key from the key module is
used to sign it. In addition, the public key from the key module is
automatically installed to /system/etc/security/apex.

48ca7dc535 Add apex variants
Now, APEX-aware modules (the ones implementing android.ApexModule
interface) are created with multiple variants for each APEX that they
are included.

For example, if a module is included (either directly or indirectly -
via static linking) to two APEXs, the module is built separately for the
two APEXs (and of course separately for platform). This is a first step
to limit the symbol visibility to the modules built for APEXs; platform
private symbols and libs shouldn't be allowed for them.

In addition, the build system now tracks transitive dependencies of
the modules in APEXs. For example, if
native_shared_lib_modules:["libFoo"] then libFoo and its dependencies
are all automatically included to the APEX.

Bug: 112672359
Test: m apex.test; the built apex has additional libs (such as liblog,
libc++, ...) that are dependencies of the ones specified in Android.bp

9d45299ba4 Add ApexModule interface for APEX-aware modules
ApexModule is the interface for APEX-aware modules. The module type apex
uses the interface to get APEX-specific information from other modules,
such as the list of APEXs that a module should be built for.

A module that is included in an APEX will be built specificaly for the
APEX. This is especially required for shared libraries; we shouldn't
just copy the artifacts built for platform, because they may be linking
against private (=unstable) symbols that are not available to APEXs
which are basically unbundled.

This CL, as a first step, makes cc.Module an APEX-aware module type.

Bug: 112672359
Test: m apex.test; the built apex has all the direct and transitive
shared lib dependencies of the libs and executables listed in Android.bp

031d2b32e3 Support prebuilt shared libs end with versions
This commit changes how `cc/androidmk.go` generates LOCAL_MODULE_STEM,
LOCAL_MODULE_SUFFIX, and LOCAL_BUILT_MODULE_STEM.  Now, `splitFileExt()`
takes a file name and a list of expected file extensions.
`splitFileExt()` searches the first occurrence of expected file
extensions in the file name.  If it can not find any, it will simply
return the last file extension.

Before this commit, `cc/androidmk.go` simply extracts the last file
extension (e.g. `.so`).  However, if the prebuilt shared libs end with
version numbers (e.g. `libc++.so.1`), it will use `$(LOCAL_MODULE).1` as
LOCAL_BUILT_MODULE_STEM and this will lead to missing target ninja
error.

5a8d1bee89 Add prebuilt_etc_xml
prebuilt_etc_xml installs an xml file to <partition>/etc[/<subdir>] and
validates the xml file against the given DTD file before installing it.

This change also includes some fixes for prebuilt_etc which is the super
module of prebuilt_etc_xml:

1) The module is changed to arch-specific module as the prebuilts are only
for devices (installed under the etc dir), but not for hosts.

2) Dependency to android.Prebuilt is removed because android.Prebuilt is
intended to be used for the case when a module can exist as prebuilts,
source or both. These prebuilt_etc_* modules are prebuilt only.

3) srcs property which accepts a list of source files is changed to src
that only accepts single source file, which makes more sense for
prebuilts.

c678ad3f71 Adding java_sdk_library
java_sdk_library is to make a Java library that implements optional
SDK APIs to apps. It is actually a wrapper for several modules: 1) stubs
library that clients are linked against to, 2) droiddoc module that
internally generates API stubs source files, 3) the real runtime shared
library that implements the API, and 4) XML file for adding the runtime
lib to the classpath at runtime if requested via <uses-library>.

Note: this is only the initial CL for the feature. Followings are features
currently missing and under development.

1) check for API consistency
2) install stubs libs as the dist artifacts
3) ensuring that apps have appropriate <uses-library> tag
4) disallowing linking to the runtime shared lib
5) HTML generation

374510bcb6 Allow platform modules to link to vendor public libraries
Normally, when building with VNDK, platform modules are not allowed to
link against vendor libraries, because the ABI of the vendor libraries
are not guaranteed to be stable and may differ across multiple vendor
images.

However, the vendor public libraries are the exceptions. Vendor public
libraries are vendor libraries that are exposed to 3rd party apps and
listed in /vendor/etc/public.libraries.txt. Since they are intended to
be exposed to public, their ABI stability is guaranteed (by definition,
though it is up to the vendor to actually guarantee it).

This change provides a way to make a vendor lib as public by defining a
module of type 'vendor_public_library' with a map file that enumerates
public symbols that are publicized:

cc_library {
   name: "libvendor",
   proprietary: true,
   ...
}

vendor_public_library {
   name: "libvendor",
   symbol_file: "libvendor.map.txt",
}

This defines a stub library module named libvendor.vendorpublic from the
map file. `shared_libs: ["libvendor"]` is redirected to the stub library
when it is from the outside of the vendor partition.

When BOARD_VNDK_VERSION := <VNDK version>, or
PRODUCT_EXTRA_VNDK_VERSIONS includes the needed <VNDK version> list,

Each prebuilt VNDK module uses "vndk_prebuilt_shared" for shared
VNDK/VNDK-SP libs.

Following is the sample configuration of a vndk snapshot module:
vndk_prebuilt_shared {
    name: "libfoo",
    version: "27",
    vendor_available: true,
    vndk: {

        arm: {
            srcs: ["arm/lib/libfoo.so"],
        },
    },
}

Jacoco in Soong is done entirely using jars.

Instrumentation is enabled by EMMA_INSTRUMENT=true, and affects
all apps.  If EMMA_INSTRUMENT_FRAMEWORK=true then it also affects
any java libraries listed in InstrumentFrameworkModules.

1369cdb280 Initial support for converting jars to java9 system modules
Adds a java_system_modules module type that (when
EXPERIMENTAL_USE_OPENJDK9 is set to true) converts a list of
java library modules and prebuilt jars into system modules,
and plumbs the system modules through to the javac command
line.

Also exports the location of the system modules to make
variables, as well as the name of the default system module.

Test: TestClasspath in java_test.go, runs automatically as part of the build

9d6c6722a7 Rename target.linux[_x86[_64]] to target.linux_glibc[_x86[_64]]
In the future, target.linux will apply to all targets running a linux kernel
(android, linux_glibc, linux_bionic). So move all current users to the specific
linux_glibc.

There will be another cleanup pass later that will move some instances back to
target.linux if the properties should be shared with target.android and
target.linux_bionic, but target.linux needs to be removed first.

ada83ec0a6 Add PGO support to soong
Bug: http://b/63768402
Bug: http://b/65598278

Add support for the 'pgo' property to specify how a module is processed
under PGO.  A sample property is below:

pgo: {
    instrumentation: true, // could be "sampling: true" when supported
    profile_file: "pgo_simple.profdata",
    benchmarks: ["pgo_simple"],
}

1. Runtime profiles can be gathered using "sampling" or
"instrumentation".  Sampling is not supported initially.

2. If 'toolchain/pgo-profiles' project is found,
'toolchain/pgo-profiles/${profile_file}' is passed to the compiler and
linker when building this module.

3. If ANDROID_PGO_INSTRUMENT environment variable is set, and includes a
benchmark in the 'benchmarks' list, appropriate flags (for e.g.
-fprofile-generate for instrumentation) are passed to the compiler and
linker when building this module.

Test: Add example modules that specify the pgo property and verify
appropriate flags and dependencies in the Ninja file.  Some
tests/examples are in https://android-review.googlesource.com/474805

c77a0b3f9c Extract the linker and embed it into host bionic binaries
The linux kernel requires that the ELF interpreter (runtime linker)
that's referenced by PT_INTERP be either an absolute path, or a relative
path from the current working directory. We'd prefer a relative path
from the binary, similarly to how we handle looking up shared libraries,
but that's not supported.

Instead, extract the load sections from the runtime linker ELF binary
and embed them into each host bionic binary, omitting the PT_INTERP
declaration. The kernel will treat it as a static binary, and we'll use
a special entry point (linker_wrapper) to fix up the arguments passed by
the kernel before jumping to the embedded linker. From the linker's
point of view, it looks like the kernel loaded the linker like normal.
