lib: robust locking in shared memory and crash recovery
This PR enhances the shared memory providing recovery if a process crashes. It adds a SHM_DU_TIMEOUT_MICROS variable, setting an expiration time for SDU's when shared memory is full. If an application doesn't read a blocking SDU within this time, the shared memory will be cleansed of all SDU's for this application and the application's rbuff will be cleared. Some refactoring of the API's. Fixed wrong pthread checks in IRMd. Fixes #13 Fixes #14
