The 'Timer::Session::msleep' function is one of the last occurrences of long-blocking RPC calls. Synchronous blocking RPC interfaces turned out to be constant source of trouble and code complexity. I.e., a timer client that also wants to respond to non-timer events was forced to be a multi-threaded process. This patch replaces the blocking 'msleep' call by a mechanism for programming timeouts and receiving wakeup signals in an asynchronous fashion. Thereby signals originating from the timer can be handled along with signals from other signal sources by a single thread. The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA, L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this patch adds the timer test to autopilot. Fixes #1
