usb_util: add sandboxed-libusb feature make open_fd patch optional. if sandboxed-libusb feature is not selected, open_fd is not required. In this case, the code must have access to /dev/bus/usb, and not external fd is needed.

assertions: Use compile-time assertion macro This depends on the `assertions` crate added in CL:1366819. `const_assert!(boolean expression)` is a compile-time assertion that fails to compile if the expression is false.

sync: Mutex type with methods that panic instead of return error This CL adds a crate `sync` containing a type sync::Mutex which wraps the standard library Mutex and mirrors the same methods, except that they panic where the standard library would return a PoisonError. This API codifies our error handling strategy around poisoned mutexes in crosvm. - Crosvm releases are built with panic=abort so poisoning never occurs. A panic while a mutex is held (or ever) takes down the entire process. Thus we would like for code not to have to consider the possibility of poison. - We could ask developers to always write `.lock().unwrap()` on a standard library mutex. However, we would like to stigmatize the use of unwrap. It is confusing to permit unwrap but only on mutex lock results. During code review it may not always be obvious whether a particular unwrap is unwrapping a mutex lock result or a different error that should be handled in a more principled way. Developers should feel free to use sync::Mutex anywhere in crosvm that they would otherwise be using std::sync::Mutex.
