Add libzfs_error_init() function
All fprintf() error messages are moved out of the libzfs_init() library function where they never belonged in the first place. A libzfs_error_init() function is added to provide useful error messages for the most common causes of failure. Additionally, in libzfs_run_process() the 'rc' variable was renamed to 'error' for consistency with the rest of the code base.
