rust/bt-mcs: Add McsServer and publish GATT service

Implement `McsServer` and `LocalServiceState` state machine managing
the asynchronous GATT publication lifecycle for Media Control Service
(MCS) and Generic Media Control Service (GMCS).

Add `McsServerBuilder::build` and `McsServer::publish` methods to
support registering the service in the GATT database.

Bug: 540400364
Test: cargo test -p bt-mcs

Bluetooth Shared Libraries

What is this?

This is a repository for shared libraries and tools that can be useful for multiple Bluetooth stacks.

These tools and libraries are meant to be:

  • Stack-agnostic and platform-agnostic
  • Implement a useful subset of a published Bluetooth specification.

It has been started as a repository for developing Rust crates but can be easily expanded to include libraries and tools written in other languages.

What is this not?

It is not a full Bluetooth stack. Google has two officially open-source Bluetooth stacks:

Structure

  • rust - Rust Crates
  • docs - General documentation (documentation for each library/tool is included in their directories)
