Added new Scalpel library interface functions. libscalpel_initialize() opens the audit file, reads the configuration file, allocates storage and sets up the thread pool. libscalpel_carve_input() is called for each file to be carved. libscalpel_finalize() releases the resources that were set up in libscalpel_initialize.
The old library API function, scalpel_carveSingleInput() will be removed once applications that use it have been updated.
Added a note to scalpel_carveSingleInput() that it has been deprecated and should not be used.
