- Reorder some internal struct members so that less padding is used. This is an attempt at saving a bit of space by packing some structs (using pahole to find the holes) where it might make sense to do so without losing readability. I.e., I tried to avoid separating fields that seem grouped together (like the cwd... fields in struct ftp_conn for instance). Also abstained from touching fields behind conditional macros as that quickly can get complicated. Closes https://github.com/curl/curl/pull/6483
