RS CHANGES: - Crash recovery is now implemented like live update. Two instances are kept side by side and the dead version is live updated into the new one. The endpoint doesn't change and the failure is not exposed (by default) to other system services. - The new instance can be created reactively (when a crash is detected) or proactively. In the latter case, RS can be instructed to keep a replica of the system service to perform a hot swap when the service fails. The flag SF_USE_REPL is set in that case. - The new flag SF_USE_REPL is supported for services in the boot image and dynamically started services through the RS interface (i.e. -p option in the service utility). - Fixed a free unallocated memory bug for core system services.
