Removed the check for denormalized names from "svnadmin verify".
We're really only interested in possible name collisions, not
individual names.

* subversion/include/svn_repos.h (svn_repos_notify_warning_t):
   Removed enumeration constants svn_repos_notify_warning_denormalized_name
   and svn_repos_notify_warning_denormalized_mergeinfo.
  (svn_repos_verify_fs3): Updated docstring.
* subversion/svnadmin/svnadmin.c (options_table):
   Updated documentation for the --check-normalization option.
* subversion/libsvn_repos/dump.c (normalized_unique, normalized_collision):
   Added documentation.
  (check_path_normalization): Removed.
  (verify_mergeinfo_normalization):
   Removed check for individual denormalized names.
  (add_directory, add_file): Removed calls to check_path_normalization.
* subversion/tests/cmdline/svnadmin_tests.py (verify_denormalized_names):
   Updated the expected output to account for the changed semantics
   of "svnadmin verify --check-normalization".
