Users of the rust_protobuf module can use the 'use_protobuf3'
option to select version 3 of the protobuf crate instead of the
current default of version 2. This unblocks teams that would like
to use protobuf 3 immediately and provides a mechanism for us to
incrementally migrate users of protobuf 2 to protobuf 3.
Test: Adds tests that are executed during every build.

aosp/2518976 revealed a pre-existing bug, which was that some Rust test
targets did not have all of their shared library dependencies packaged in
the host-unit-tests.zip file. Conveniently enough, these targets did not
actually depend on any of the symbols in the missing shared libraries, so
their DT_NEEDED entries were being removed by the --as-needed flag being
passed to the linker by rustc. This flag was dropped when we switched
to running the link command directly, causing the DT_NEEDED entries to
reappear and leading to runtime failures for these test binaries.
Although we could fix the issue that prevented these (unused) dependencies
from being packaged, there wouldn't be much point in doing so because
we already know that they aren't needed. So for now, let's return to
the status quo and keep passing --as-needed to the linker.

Teach rustc to generate object files instead of a linked executable
for binary and shared library crates. This lets us skip the lengthy
Rust compilation phase when only the C++ dependencies of these crates
have changed.
This works using a Python script that replaces the linker invoked by
rustc and converts the linker command line into a rspfile that can be
used during the link phase. The script makes certain assumptions about
how rustc invokes the linker, but since we control the version of Rust
we use, we can update the script if those assumptions ever break. I've
asked the Rust developers about adding an official way to do this so
hopefully we won't need to rely on this hack in the future.
The rustc rule for Kythe has been altered to pass linker=true, somewhat
consistent with the main rustc rule, which now doesn't invoke the actual
linker either. `m xref_rust` still succeeds, but hopefully we can find
someone who knows more about the rest of the Kythe pipeline who can let
us know whether it should still work. Otherwise, let's use this CL as
an opportunity to find out whether the rest of the pipeline is happy
with linker=true, since otherwise we will find it hard to maintain the
Kythe rule in the future.

Some Rust crates with no src_deps have generated files checked in in an
"out" subdirectory and included via a reference to $OUT_DIR, such as
external/rust/crates/userfaultfd-sys.
Astonishingly, some people must be leaving $OUT_DIR set to the default
value of "out", because with $OUT_DIR set to this value, building these
crates would presumably succeed. For everyone else, the build fails
when building one of these crates because it will attempt to load from
the wrong directory. Presumably these crates should be using src_deps
instead (and once that's fixed, we should probably *unset* $OUT_DIR in
rustc invocations to prevent the same thing from happening again), but
for now, fix the build with non-default OUT_DIR by explicitly setting
OUT_DIR to "out" if there are no src_deps.

Coverage builds for no_std crates currently fail because
profiler_builtins are part of libstd and therefore do not get included.
When calculating the dependencies for coverage enabled targets, check if
the stdlib is being included, and if it is not then pull the
profiler_builtins sysroot.

Fix an issue where rust_fuzz modules were
not correctly packaging and copying their
dependencies.
This is done by extending the CC fuzz packager
to simply handle both Rust and CC modules,
ensuring this doesn't get out of sync again.
Fuzzer related functions are added to the
Linkable interface to facilitate this.
There was a bug where the Make definitions for
Rust fuzzers were not being created as well,
and that is addressed here.
