809d51866a Heed SkipInstall flag when adding install rules for vendor-snapshot.
The prebuilt-vs-source selection operates by setting SkipInstall on
either module. When the vendor-snapshot module visits all modules it
will visit both, and if it is a static library it will then add
duplicate install rules for both source and prebuilt unless it
looks at SkipInstall.

Test: `m nothing` in a tree with prebuilts/runtime present, that
  has been updated with a snapshot after https://r.android.com/1398472,
  which started to propagate vendor_available flags to prebuilts
  snapshots.

945441c09a Add exclude_from_vendor_snapshot property, related logic
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.

d458745f15 cc: export Stripper struct
The cc stripping logic can be reused for Rust. Export the Stripper
structure for that purpose. Extract the strip-related flags from
builderFlags into StripFlags. Add the method flagsToStripFlags
(similarly to flagsToBuilderFlags).

Add the helper method disableStripping on libraryDecorator.

c42f2f2e9d Add cfi static libraries to vendor snapshot
CFI modules can't link against non-CFI static libraries, and vice versa.
So without capturing both CFI and non-CFI static libraries, vendor
modules won't be able to use CFI, which will be a critical security
hole.

This captures both CFI and non-CFI variants of all static libraries for
vendor snapshot, except for those whose cfi are explicitly disabled.

For example, suppose that "libfoo" is defined as follows.

cc_library_static {
    name: "libfoo",
    vendor_available: true,
}

As it doesn't have cfi disabled, two libraries "libfoo.a" and
"libfoo.cfi.a" will be captured. When installed, vendor snapshot module
for "libfoo" will look like:

vendor_snapshot_static {
    name: "libfoo",
    src: "libfoo.a",
    cfi: {
        src: "libfoo.cfi.a",
    },
}

The build system will recognize the "cfi" property, and will create both
CFI and non-CFI variant, allowing any modules to link against "libfoo"
safely, no matter whether CFI is enabled or not.

Two clarification:

1) The reason why we don't create separate modules is that DepsMutator
runs before sanitize mutators. CFI and non-CFI variant of a library
should exist in a single module.

2) We can't capture CFI variant if the source module explicitly disables
cfi variant by specifying the following.

sanitize: {
    cfi: false,
}

In this case, only non-CFI variant will be created for the vendor
snapshot module.

7d3f096cf4 Include shared lib in vendor snapshot if isVndkExt
A VDNK extension is an image:vendor module provided by a
vendor-modified framework project. So it should be
provided to the vendor build as a prebuilt (for the
purposes of building against a vendor snapshot).

65ca36a72e Exclude kernel_headers from vendor snapshot

installed to vendor. kernel_headers are excluded from snapshot because
they always depend on vendor, regardless of locations they are defined.

7f283f4bd0 Refine logic choosing vendor snapshot modules
This refines the vendor snapshot codes in order to fix logic errors.

- Capture toolchain_library and cc_library_headers correctly.
- Redirect unwind static library correctly.
- Filter out sanitize / coverage / lto by looking at HideFromMake.
- Add binary() function for clear and shorter codes.
- Include test modules.
- Add more tests to prevent further snapshot breakages.

will allow deleting all of the copied/linked NOTICE files.

5f64aeccdf Fix .vendor suffix for snapshots
.vendor suffix is meant to be attached for vendor variants of
modules without "vendor: true". So when we decide whether the suffix is
needed for a snapshot module, we should check if corresponding source
module is "vendor: true" or not, instead of checking vendor_available of
the source module.

8471cdaced Implement vendor snapshot
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.
