--print-env prints the same environment variables used by build.py, this
is useful for setting up external tools like rust-analyzer.

The output can be `eval`-ed directly in shell or copied to the external
tool's configuration.

If we attempt to start multiple times and are unsuccessful, try using
the reset mechanism to recover instead of trying to start.

This also changes the condition for attempting a restart/reset from
depending on device presence. On Linux, when we bind the socket as
userchannel, the device presence is false (index is removed). It makes
more sense to attempt retry if we want the device enabled.

Removed the separate bootstrap.py and merged its functionality into
build.py. With all the changes, this is how you do bootstrapping
+ building now:

./build.py --run-bootstrap
./build.py

This changes defaults to something reasonable in the scripts. A few of
the defaults that were changed:

* Set bootstrap dir default to ~/.floss
* Libdir changed to /usr/lib
* Clang made default and --no-clang added instead
* Vendored rust made default and --no-vendored-rust added instead

Writing topshim interfaces is very tedious and lots of code is
duplicated in C++. Rather that depend on unsafe C++ code, we write
a small amount of unsafe Rust code and use macros to interact with the
native layer directly from Rust.

A few major changes introduced in this patch:
- Bindgen to get Rust interface into C
- Macros to call raw pointer functions directly
- Macros to handle converting a callback into an enum variant
- Refactor code to use new data structures
- Replace use of closures for callbacks with an enum and dispatch fn

This change also updates the bindgen requirement to 0.57 to match what
Android is already using.

BYPASS_INCLUSIVE_LANGUAGE_REASON=Bindgen dependency provides this api

This adds a script that can build system/bt locally on your Linux
machine. Please see required folder layout in the script on how to
prepare your environment and check the help text on how to use it.

In its simplest form (for example):
  ./build.py --out ../build --platform-dir ../staging --clang

This will build all of systembt in ../build using the ../staging
directory as your source directory and will use the clang compiler to do
the build.
