Vendors can now generate only needed modules by setting the following
Makefile variables:
- DIRECTED_VENDOR_SNAPSHOT: set to true
- VENDOR_SNAPSHOT_MODULES: list of snapshot candidates
e.g.
DIRECTED_VENDOR_SNAPSHOT := true
VENDOR_SNAPSHOT_MODULES := toybox_vendor sh_vendor libbase libcutils ...
Bug: 157967325
Test: m dist vendor-snapshot after setting those in BoardConfig.mk

Also some files are refactored:
- snapshot_prebuilt.go is separated from vendor_snapshot.go. Now
vendor_snapshot.go contains snapshot generation codes, while
snapshot_prebuilt.go contains module definition codes.
- Some helper functions are moved from snapshot_utils.go to util.go.
- Some ambiguous names of types and functions are renamed.
We still can add more detailed comments about the snapshots. They are to
be uploaded in follow-up changes, to avoid making this change too big.

The android.WriteFile rule takes careful escaping to produce the
right contents. Wrap it in an android.WriteFileRule that handles
the escaping.
Test: compare all android.WriteFile outputs

Export information about static libraries, shared libraries and
exported flags through Providers instead of accessing the module
directly. Much more is left to be converted, but this significantly
simplifies the dependencies on libraries with stubs by making it easy
for a module to masquerade as another by simply exporting the
providers from the other module. Instead of depending on all the
versions of a library and then picking which one to use later, it
can depend only on the implementation variant and then select the
right SharedLibraryInfo from the variant.
Test: m checkbuild
Test: only expected changes to build.ninja

A global variant was used to store the global mapping between
modules and APEXes. Replace it with storing pointers to APEX
contents inside each module so that they can query the contents
of any APEXes they belong to.
Bug: 146393795
Test: all Soong tests
Test: single line change to build.ninja host install dependency ordering
Test: no Android-${TARGET_PRODUCT}.mk, make_vars-${TARGET_PRODUCT}.mk or late-${TARGET_PRODUCT}.mk

When building a vendor snapshot, the general rule the
build system uses to select a module for inclusion into
the vendor snapshot is if it's a framework module.
However, there are cases where a partner may modify the
framework module, thereby assuming control of that
module.
This change adds the exclude_from_vendor_snapshot
property allowing the partner to mark a module that
would normally be included in the vendor snapshot for
exclusion. This module is then built from source when
building the vendor image against the vendor snapshot.

VNDK and vendor snapshot singleton work in a single thread, so globbing
in singleton results in ridiculus running time. Moving codes to
GenerateAndroidBuildActions to reduce running time.
Bug: 150406226
Test: VNDK_SNAPSHOT_BUILD_ARTIFACTS=true m dist vndk vendor-snapshot
Test: vendorSnapshotSingleton build time became 0.56s (from 10s)
Test: build.ninja building time became 1m11s (from 1m21s)

As a second step to removing the go/android3p instructions to copy or
to link NOTICE to LICENSE, include LICENSE files in the notices, which
will allow deleting all of the copied/linked NOTICE files.
The change causes a few additions to the system image notice files.
Test: manually built and compared before and after notices

This implements four modules (static/shared/header libraries, and
binaries) for vendor snapshot. These modules will override source
modules if BOARD_VNDK_VERSION != current.
Bug: 65377115
Test: 1) VNDK_SNAPSHOT_BUILD_ARTIFACTS=true m dist vndk vendor-snapshot
Test: 2) install snapshot under source tree
Test: 3) set BOARD_VNDK_VERSION and boot cuttlefish

Vendor snapshot can be captured with "m dist vendor-snapshot". With
vendor snapshot and vndk snapshot, older version of /vendor and newer
version of /system will be able to be built together by setting
BOARD_VNDK_VERSION to past vendor's version.
Only vendor modules under AOSP are to be captured. In detail, modules
under following directories are ignored:
- device/
- vendor/
- hardware/, except for interfaces/, libhardware/, libhardware_legacy/,
and ril/
Test modules (cc_test, etc.) and sanitized modules are also ignored.
