Eliminate a few sprintf calls for printing numbers.

* subversion/mod_dav_svn/merge.c (dav_svn__merge_response): 
* subversion/clients/cmdline/status.c (print_status): 
  Replace sprintf with apr_psprintf for revision numbers.

* subversion/clients/cmdline/ls-cmd.c (print_dirents):
  Replace sprintf with apr_psprintf for file size.
