Guest previously had its own idea of active, and this is slightly confusing. This commit removes that, and instead lets the Upstairs tell consumers if it is active or not. Additionally, getting the length of a Buffer shouldn't take a lock. Make `len()` and `is_empty()` synchronous by storing the length (it shouldn't change!). Closes oxidecomputer#461
