  Log:
  MFC 1.280 (by des):
  
  | Two minor optimizations of fdalloc():
  |
  |  - if minfd < fd_freefile (as is most often the case, since minfd is
  |    usually 0), set it to fd_freefile.
  |
  |  - remove a call to fd_first_free() which duplicates work already done
  |    by fdused().
  |
  | This change results in a small but measurable speedup for processes
  | with large numbers (several thousands) of open files.
