when the code is about to use the [ug]id_ndx value as an index (since
this saves a memory reference).

user specified -X twice.

values to index into the file-list extra-attribute array instead
of abusing the preserve_FOO variables.

it should free all old mem and reset to an empty state.

we use less memory, especially in small transfers.  As file lists are
discarded, we use the new pool_boundary() and pool_free_old() functions
to discard pool extents that are no longer needed.

- Added a pool_boundary variable to struct file_list.

free all wholly affected extents older than a particular point in time.

punctuation, and fix some typos.

  item was trying to make that memory available to the pool, but it
  failed to adjust the right variable.
- Fixed a bug in pool_free() where the return of the entire live
  extent back to unallocated status did not obey POOL_CLEAR.
- Use the new() and new_array() functions instead of malloc().
- Changed the sqew variable to skew.
- Some other minor formatting tweaks.

- Don't rewrite the last byte of a file in sparse mode when the
  file didn't end with a null char.

pointed out.

This is more in keeping with the way cp works, and also makes the dir-
joining code (in inc_recurse mode) easier.

  that ensures that any identical items in the file-list stay in the
  same order as they had in the input.  It will also obey the --qsort
  option (which causes it to punt the sort to the qsort() routine).
- Changed the various places that sort the file-list to call fsort().

recursion (at least for now).

- Added several new --no-FOO options.

- Made the keep-alive counter in touch_up_dirs() work better.
- Use !(N & 0xFF) instead of !(N % 200).

  data from the sorted parent flist.  This ensures that any entries
  marked with FLAG_DUPLICATE are in the same order in the dir_flist
  (where the flags get checked) as they are in the parent flist
  (where the flags get set).
- Made the flist_expand() function static.
- Added a growth count arg to flist_expand().
- Made make_file() set a pool variable instead of tweaking flist.
- Improved the error message when a dir-number is out of bounds.

of the Solaris 10 host's merge-test failure is correct or not.

extra verbose:  they now have the list's ndx_start value added in.
