Jeff Gaston 294356f045 Automatically reorder C/C++ link dependencies in Soong
This uses knowledge of transitive dependencies to reorder
linker command line arguments such that if module A depends
on module B, then module A is automatically listed before
module B in the linker command line.

This should mostly remove the need for Android.bp files to
list all of their static dependencies in link order

Bug: 66260943
Test: reorder the entries of static_libs in an Android.bp and see that linking still succeeds

Jiyong Park 6a43f04777 Squash vendor sources before linkageMutator runs
linkageMutator removes srcs property of the shared variant of a lib in
order to reuse *.o files compiled for the static variant also to the
shared variant.

However, this causes problem when vendor-specific srcs are specified in
target: {vendor: {srcs: ["..."]}}. For example, let's assume

cc_library {
    name: "libfoo",
    srcs: ["foo.c"],
    target: {
        vendor: {
            srcs: ["bar.c"],
        },
    },
}

Then,
static_vendor: inputs = foo.o, bar.o
shared_vendor: inputs = foo.o (from static_vendor), bar.o (from
static_vendor), bar.o

So, bar.o is included twice and this causes multiple symbol definition
error.

In order to handle the problem, vendor mutator is applied before the
linkage mutator and the vendor-specific srcs are squashed in the vendor
mutator.

Colin Cross dd84e056ed Dedup exported flags from dependencies
Soong command lines have gotten very long due to hidl modules
reexporting lots of libraries.  Dedup the include dir flags.

Test: m -j checkbuild
