GLib-style interface to binder (Android IPC mechanism)
Key features:
1. Integration with GLib event loop
2. Detection of 32 vs 64 bit kernel at runtime
3. Asynchronous transactions that don't block the event thread
4. Stable service manager and low-level transaction APIs
Android keeps changing both low-level RPC and service manager
protocols from version to version. To counter that, libgbinder
implements configirable backends for different variants of those,
and yet keeping its own API unchanged.
