cc.Module.staticVariant is used to track the corresponding static
variant of a shared variant. This change fixes a problem that the
staticVariant field is not correctly set when the lib is with stubs:
{...}. This was happening because the staticVariant was set by adding
dependency from shared variant to static variant to reuse object files.
However, for a lib with stubs, the dependency was not created because it
does not make sense to share object files for stubs lib where source
code is auto-generated.
Fixing the issue by adding dependency to the static variant with a
different dependency tag whose only purpose is to set staticVariant
field.

This change fixes a bug that sanitizer runtime libs for non-core variant
(e.g. recovery, vendor, etc.) are not installed. It happened because the
dependency to the sanitizer runtime lib was without 'image' variant,
which in most case caused only the core variant - which is the first in
the image variants - of the lib to be installed.
Fixing the issue by correctly selecting image variant depending on the
location of the lib having dependency to the runtime lib.

A module can be built multiple times when it is referenced from one

differently depending on the context; e.g., do A when built form
APEX M, do B when built for APEX N, and do C when built for platform.

This change first introduces the interface "Sanitizeable" that
module types other than cc.Module can use to be handled by the sanitizer
mutator. APEX module, by implementing the interface, gets sanitizer
variants.
In doing so, sanitizer.go is refactored so that modules have explicit
dependencies to the runtime sanitizer libraries. This allows the runtime
library to be packaged into the APEX when required. This also completes
the dependency graph; updating the prebuilt sanitizer runtime will
trigger rebuilding of modules using the runtime.

If a lib is directly included in an APEX (via native_shared_libs
property) and the lib has stubs (via stubs.versions property), then the
ordinary non-stubs variant of the library is renamed to
<libname>.bootstrap in the makefile. At the same time, the stubs variant
of the lib becomes visible and it's name is <libname>.
This ensures that modules in Android.mk build against the stubs
variant thus preventing them from using private APIs in the lib.
The non-stubs variant, however, is used if the module explicitly has
set the new 'bootstrap' property to true. This is useful for building
some early binaries (such as init and vold) which need to run before
APEXes are activated. Since they can't use the bionic libs from the
runtime APEX, they should use the bionic libs left in the system
partition which is called the boostrap bionic.

This change fixes following problem:
1) a native lib having stubs is defined.
2) the lib is included in an APEX.
3) a static binary is linking the lib from outside of the APEX.
4) then, the dependency from the binary to the lib is vanishing.
This is happening because cc.depsToPaths() mistakely does not
distinguish static lib deps from shared lib deps. For shared lib deps,
it creates two dependencies (one for stubs variant and the other for
non-stubs variant) and choose the stubs variant when the lib and the
current module is not in the same APEX (i.e. dependency to the non-stubs
variant is discarded). However, since we don't have stubs variant for
static library, it ends up having no dependency to the library if the
link is static.
Fixing the issue by skipping the variant selection routine when the link
is static.

This change fixes a problem that APEX variations are created for the
modules that actually shouldn't built for any APEX. For example,
consider this case.
apex { name: "myapex", native_shared_libs: ["mylib"],}
cc_library { name: "mylib", shared_libs: ["libfoo#10"],}
cc_library { name: "libfoo",
shared_libs: ["libbar"],
stubs: { versions: ["10"], }, }
cc_library { name: "libbar", ...}
Before this change, both the stubs and non-stubs variations of libfoo
were mutated with apexMuator, which is incorrect for the non-stubs
varia; there is no dependency chain from the apex "myapex" to the
non-stubs variation, but to the stubs variation due to the #10 syntax.
This was happening becauses we used the name of the module to determine
whether it should be built for APEX or not. Both stubs and non-stubs
variations have the same module name "libfoo".
Fixing this issue by recording the list of APEX variations required
directly on the module. So, the stubs variation of libfoo has myapex in
its apex variations list, but the non-stubs variation doesn't, and thus
apexMutator does not pick up the non-stubs variation.

When a native module is built for an APEX and is depending on a native
library having stubs (i.e. stubs.versions property is set), the stubs
variant is used unless the dependent lib is directly included in the
same APEX with the depending module.
Example:
apex {
name: "myapex",
native_shared_libs: ["libX", "libY"],
}
cc_library {
name: "libX",
shared_libs: ["libY", "libZ"],
}
cc_library {
name: "libY",
stubs: { versions: ["1", "2"], },
}
cc_library {
name: "libZ",
stubs: { versions: ["1", "2"], },
}
In this case, libX is linking to the impl variant of libY (that provides
private APIs) while libY is linking to the version 2 stubs of libZ. This is
because libY is directly included in the same apex via
native_shared_libs property, but libZ isn't.

A cc_library or cc_library_shared can be configured to have stubs
variants of the lib.
cc_library_shared {
name: "libfoo",
srcs: ["foo.cpp"],
stubs: {
symbol_file: "foo.map.txt",
versions: ["1", "2", "3"],
},
}
then, stubs variants of libfoo for version 1, 2, and 3 are created
from foo.map.txt. Each version has the symbols from the map file where
each symbol is annotated with the version that the symbol was introduced
via the 'introduced=<ver>' syntax. The versions don't need to be in sync
with the platform versions (e.g., P for 28). The versions are local to
the library.
For another library or executable to use the versioned stubs lib, use
the new 'name#ver' syntax to specify the version:
cc_binary {
name: "test",
....
shared_libs: ["libFoo#2"],
}
Internally, a new mutator 'version' is applied to all cc.Module objects.
By default, a variant named 'impl' is created for the non-stub version.
If the versions property is set, additional variations are created per a
version with the mutable property BuildStubs set as true, which lets the
compiler and the linker to build a stubs lib from the symbol file
instead from the source files.
This feature will be used to enforce stable interfaces among APEXs. When
a lib foo in an APEX is depending on a lib bar in another APEX, then bar
should have stable interface (in C lang) and foo should be depending on
one of the stubs libs of bar. Only libraries in the same APEX as foo can
link against non-stub version of it.

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

which are basically unbundled.
