This fixes an issue with -K noticed by eric casteleijn, avoids some
inconsistent itemizing when a file/dir is replaced by a dir/file,
and removes a now-obsolete chunk of code from make_file().

(see f41152d3), so remove the inaccurate
"p" from the man page.  Noticed by Jacob Balazer:

as reported in bug 5851.

Gets rid of a DNS delay waiting for a lookup failure.

to a *-1 or *-2 directory.  A few other minor improvements.

- Mention how many files were created (protocol >= 29).
- Mention how many files were deleted (new in protocol 31).
- Follow the file-count, created-count, and deleted-count
  with a break-out list of each count by type.

a crash when the xattr pointer's memory happens to start out non-zero.
Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.

no short options specified.

incremental recursion is active.  Added test.

- Prompt the user for the parameters when missing.
- Allow the creation of a module without a user+password.

Fixed a just-introduced problem with a relative module-path.

- Free a mergelist's parent_dirscanned filters the last time it is
  popped or as soon as the filters are discarded due to the "n"
  modifier.  Aside from not leaking memory, this is needed to clean up
  any mergelists defined during the parent_dirscan to avoid crashing by
  trying to restore nonexistent state for them in pop_local_filters.
- Make push_local_filters save the current mergelist_cnt, and make
  pop_local_filters assert that it has the correct number of mergelists
  before restoring their state.
- Assert that mergelists get deactivated in strict LIFO order to catch
  any glitches as soon as they happen.  Free linked lists of filters in
  reverse order to make that the case.
- Add a bunch of mergelist-related debug output (--debug=filter2).

Also improved the human-readable output functions, including
adding the ability to output negative numbers.
