Hcidoc will be used to analyze snoop files and snooz files to identify
errors and other behaviors. This commit simply sets up the hcidoc crate
and a simple snoop reader.

Ran a sed rule to replace most instances of //bt to //bt/system in all
BUILD.gn and *.gni files. Also made some manual changes to include
directories using packetgen and dumpsys to include bt/system/gd instead
of just bt/gd. Added a new BUILD.gn at root that just points to
system/BUILD.gn.

On the Rust side, updated the Cargo.toml paths and build.rs includes for
topshim.

This reverts commit ddd429fe.

As it turns out, we will need to change //bt to //bt/system after all
because the ChromeOS ebuild can't easily handle the subdirectory change
otherwise.

This adds the minimal command line client with Bluetooth stack embedded
into the client. Future work will add support for the Bluetooth stack
over D-Bus.

Test: manual - Build floss on Linux, run btclient

This cleans up compiler warnings and removes unused binary in "adapter"
crate.

The D-Bus daemon connects the RPC-agnostic API implementations in
`btstack` crate with the `dbus_projection` to make a D-Bus projection of
the API implementation.

Test: manual - Use dbus-send util
Change-Id: I12391f4e9739a5d1ed6167990fc016429e7280d4

In order for the Rust front-end to use the bluetooth interface, add
a topshim to give Rust code access to C++.

Also includes some debug code in adapter/main.rs which will eventually
be replaced with a proper dbus frontend.

Rather than using C++ binaries to link with Rust staticlib, we do it the
other way around. This allows us to write our dbus frontend with Rust
instead.

ChromeOS is missing support for mixing C++ and Rust in GN so we compile
Rust in a separate step using Cargo. Currently, only the direct code
portions were copied to the Cargo.toml and tests are still missing. The
final output from the Rust build is the libbt_shim_ffi staticlib.

Some BUILD.gn rules for rust libraries were also added (to try to make
it work with an experimental Rust toolchain in GN) but was abandonded
because dependencies couldn't be built. Leaving this in since it will be
useful when GN supports building Rust as well on ChromeOS.
