This commit introduces the new `Component` interface in the form of the headers base/component.h and base/entrypoint.h. The os/server.h API has become merely a compatibilty wrapper and will eventually be removed. The same holds true for os/signal_rpc_dispatcher.h. The mechanism has moved to base/signal.h and is now called 'Signal_handler'. Since the patch shuffles headers around, please do a 'make clean' in the build directory. Issue #1832
