Distinguish restart_new_emulator from restart_emulator in upgrade instructions
Earlier, there was only one valid instruction to restart the emulator in an appup/relup script, 'restart_new_emulator'. A new instuction, 'restart_emulator', is now added, and the meaning is as follows: 'restart_new_emulator' is mainly for the core applications (erts, kernel, stdlib and sasl), and it indicates that there is new core functionality in the release and the emulator needs to be restarted before executing the upgrade scripts. If this instruction exists, a temporary release will be created which consists of the new version erts, kernel, stdlib and sasl, and the old versions of all other applications. After restarting the emulator with this temporary release, the rest of the upgrade instructions are executed, including loading of new versions. 'restart_emulator' can be used by any application if a restart of the emulator is needed after the upgrade instructions have been executed. In this case, the emulator will be restarted with the new release (i.e. not a tempoarary one) after all other upgrade instructions for all applications have been excecuted.
