[PATCH] libsvn-fs-util: Convert error related functions as macros

Hello,

As per the mailing list thread [1], I've converted all error related
functions in libsvn-fs-util library as macros, which allows them to
return errors with useful line number in them. Please find attached a
patch for review.

Convert the error functions in libsvn-fs-util library as macros, so it
will return errors with more useful line number in them.

  (svn_fs__err_not_mutable, svn_fs__err_not_directory,
   svn_fs__err_not_file, svn_fs__err_no_such_lock,
   svn_fs__err_lock_expired, svn_fs__err_no_user,
   svn_fs__err_lock_owner_mismatch, svn_fs__err_path_already_locked):
   Remove definition for error functions. They are replaced with a new
   macro definition.

  Remove declaration for error functions and define new macro which
  allows them to return error with more useful line number in them.
  Include svn_private_config.h header file.
