  Log:
  New file descriptor allocation code, derived from similar code introduced
  in OpenBSD by Niels Provos.  The patch introduces a bitmap of allocated
  file descriptors which is used to locate available descriptors when a new
  one is needed.  It also moves the task of growing the file descriptor table
  out of fdalloc(), reducing complexity in both fdalloc() and do_dup().
  
  Debts of gratitude are owed to tjr@ (who provided the original patch on
  which this work is based), grog@ (for the gdb(4) man page) and rwatson@
  (for assistance with pxeboot(8)).
