execute-only memory layouts via a new xom module property. Also adds
support for an ENABLE_XOM build flag for global builds.

8fd6192480 APEX can be flattened
When TARGET_FLATTEN_APEX is set to true, APEXes are flattened, which
means files in an APEX is not packaged into the mini file system image,
but instead directly copied to the system partition.

This option is for devices where kernel does not support loopback
devices or the maximum number of loopback devices is too small (though
the threshold is TBD as of now).

This CL also fixes a bug that jars having bytecode are installed instead
of those having dex.

Bug: 118485880
Test: TARGET_FLATTEN_APEX=true m apex.test; tree
out/target/product/.../system/apex/apex.test shows list of files in it.

Test; m apex.test, then a file out/target/product/.../system/apex/apex
.test.apex exists.

5a0dcd5acf Store dex files uncompressed and unstripped in privileged APKs
Privileged APKs need to store their dex files uncompressed so they
can be verified and mapped directly out of the APK.

Also track whether the module will be dexpreopted or not in order
to determine if the dex file should be stripped before signing.

0ef639bb59 Allow generating modules once per OS instead of once per Class
When building with two OSes of the same class (Host, etc) enabled,
independently produce variants of each module for each OS, instead of
making `compile_multilib: "first"` select just one of the OSes.

My use case this is for Linux + LinuxBionic, which are both considered
Host class, but this would also applied if we wanted to generate rules
for Linux+Darwin, or some combination of firmware bits (either in
addition to Android in the Device Class, or multiple firmwares in a new
Class)

8d52f86baf Fix: recovery module is disabled on 32-bit targets
Fixed a bug that recovery variant of a module is not created on 32-bit
targets. The bug was happening because the creation of the recovery
variant relied on DevicePrefer32BitExecutables() which returns false
for 32-bit only targets.

Now, recovery variant is checked against the primary architecture of the
device that is returned by DevicePrimaryArchType().

Test: m -j adbd.recovery on aosp_arm and aosp_arm64
adbd is built under recovery/root/system/bin and it is ELF32 and ELF64,
respectively for the targets.
Test: m -j libc.recovery on aosp_arm, aosp_arm64, aosp_sailfish
and the x86+arm target in mater. Only one libc.so is installed
under recovery/root/system/lib (or lib64).

0fe7866897 Add VendorConfig for board-level Soong plugin configuration
This allows Soong (Go) plugins to get custom configurations set in the
current product's BoardConfig.mk.

I'll have some more comprehensive documentation later, but the general
concept is that you'd have one namespace per plugin, defined in the
BoardConfig.mk (though they would work in the product.mk files too):

  SOONG_CONFIG_NAMESPACES += myPlugin

Within that namespace you can set key-value pairs:

  SOONG_CONFIG_myPlugin := key1 key2 ...
  ...
  SOONG_CONFIG_myPlugin_key1 := value
  ...
  SOONG_CONFIG_myPlugin_key2 := true

Then in your plugin, you can ask for your namespace:

  vars := ctx.Config().VendorConfig("myPlugin")

And then use them:

  str := vars.String("key1")
  if vars.Bool("key2") { ... }
  if vars.IsSet("key3") { ... }

Warning: It's not a good idea to fail on missing inputs, since an
android tree may contain plugins from multiple owners, and we may
configure your modules (but not build/install them) even if they're not
meant for the currently configured product.

1a5d7b1539 Add PLATFORM_SYSTEMSDK_VERSIONS and BOARD_SYSTEMSDK_VERSIONS
PLATFORM_SYSTEMSDK_VERSIONS is the list of System SDK versions that the
platform is supporting. Contrary to the public SDK where platform
essentially supports all previous SDK versions, platform support only a
few recent System SDK versions, since some of old System APIs are
gradually deprecated, removed from the following SDKs and then finally
deleted from the platform. This will be part of the framework manifest.

The list can be specified by setting PLATFORM_SYSTEMSDK_MIN_VERSION. If
it is set to an old version number, then System SDKs from the version
to the current version (PLATFORM_SDK_VERSION) are considered to be
supported by the platform. If PLATFORM_SYSTEMSDK_MIN_VERSION is not set,
only the latest System SDK version is supported.

Next, BOARD_SYSTEMSDK_VERSIONS is the list of System SDK versions that
the device is using. This is put to the device compatibility matrix
device is using. The device and the platform is considered as compatible
only BOARD_SYSTEMSDK_VERSIONS in the device compatibility matrix are
in the PLATFORM_SYSTEMSDK_VERSIONS in the framework manifest.

When BOARD_SYSTEMSDK_VERSIONS is set, a Java app or library in vendor or
odm partitions which didn't specify LOCAL_SDK_VERSION  is forced to use
System SDK. Also, the build system does the additional integrity check
to ensure that LOCAL_SDK_VERSION is within BOARD_SYSTEMSDK_VERSIONS or
PLATFORM_SYSTEMSDK_VERSIONS (if BOARD_SYSTEMSDK_VERSIONS isn't set).

18099fd856 Build with OpenJDK 9 -target 1.8 by default (attempt 4).
This is cherry-picked from attempt 3, which was reverted
due to http://b/70862583.

Before this CL topic, the build toolchain for .java source files
used OpenJDK 8, targeting 1.8 (v52 class files) by default.

This CL topic switches the default to OpenJDK 9, but still
targeting 1.8 (v52 class files) by default. If USE_ERROR_PRONE
is set to true, then the default remains OpenJDK 8.

Code in the Android platform should generally be unaffected,
but if host tools that are now compiled and run using
OpenJDK 9 are causing problems for your team, then let me
know.

To manually switch back to the old behavior for now (continue
using OpenJDK 8), run this command in your shell:
export EXPERIMENTAL_USE_OPENJDK9=false

2db7692a74 Add [soc|device|product]_specific
Added three properties (soc_specific, device_specific, and
product_specific) that shows what a module is specific to.

`soc_specific: true` means that the module is specific to an SoC
(System-On-a-Chip) and thus need to be installed to vendor partition.
This has the same meaning as the old `vendor: true` setting.

`device_specific: true` means that the module is specific to the entire
hardware configuration of a device includeing the SoC and off-chip
peripherals. These modules are installed to odm partition (or /vendor/odm
when odm partition does not exist).

`product_specific: true` means that the module is specific to the
software configuration of a product such as country, network operator,
etc. These modules are installed to oem partition (or /system/oem when
oem partition does not exist). These modules are assumed to be agnostic
to hardware, so this property can't be true when either soc_specific or
device_specific is set to true.

If PLATFORM_VNDK_VERSION has a version $VER other than "current",
install current VNDK libs to /system/lib[64]/vndk[-sp]-$VER.
Otherwise, they will be installed to /system/lib[64]/vndk[-sp].

generate build documentation.  This allows Soong to customize
the documentation.
