[PATCH v2 1/7] dir-iterator: pass name to `prepare_next_entry_data()` directly

From
Patrick Steinhardt <ps@pks.im>
Date

<12de25dfe24d61ef54e0ccc0ebd4cc69d73da50c.1708418805.git.ps@pks.im>
In-Reply-To
<cover.1708418805.git.ps@pks.im>

When adding the next directory entry for `struct dir_iterator` we pass the complete `struct dirent *` to `prepare_next_entry_data()` even though we only need the entry's name.

Refactor the code to pass in the name, only. This prepares for a subsequent commit where we introduce the ability to iterate through dir entries in an ordered manner.
