dt_from_source() and dt_from_fs() both take a filename (or directory
name) argument and open files as necessary themselves.
dt_from_blob(), however, expects the caller to open a file and pass it
in.

This patch makes dt_from_blob() take a filename and open its own
files, removing the inconsistency.  In addition, dt_from_blob() now
correctly uses dtc_close_file() to close the file opened with
dtc_open_file(), rather than directly calling fclose() on the
contained FILE *.
