refresh_index() optionally takes a seen[] array to mark the pathspec items that had matches in the index. This is used by `git add --refresh` to find out if there were any pathspec without matches, and display an error accordingly.
In the following patch, `git add` will also learn to warn about pathspecs that only match sparse entries (which are not updated). But for that, we will need a seen[] array marked exclusively with matches from dense entries. To avoid having to call ce_path_match() again for these entries after refresh_index() returns, add a flag that implements this restriction inside the function itself.
Note that refresh_index() does not update sparse entries, regardless of passing the flag or not. The flag only controls whether matches with these entries should appear in the seen[] array.
While we are here, also realign the REFRESH_* flags and convert the hex values to the more natural bit shift format, which makes it easier to spot holes.
