/* Allocate a free slot in the root directory for a new file. The file name is
   constructed after 'pattern', which must include a %d type format for printf
   and expand to exactly 11 characters. The name actually used is written into
   the 'de' structure, the rest of *de is cleared. The offset returned is to
