zimbatm 4d545297d8 lib: introduce imap0, imap1 (#25543)
* lib: introduce imap0, imap1

For historical reasons, imap starts counting at 1 and it's not
consistent with the rest of the lib.

So for now we split imap into imap0 that starts counting at zero and
imap1 that starts counting at 1. And imap is marked as deprecated.

See c71e2d4235 (commitcomment-21873221)

* replace uses of lib.imap

* lib: move imap to deprecated.nix
