Subject: refactor `seq` permutation theory

- Change the naming of permutation lemmas so they conform to a
consistent policy: `perm_eq` lemmas have a `perm_` (_not_ `perm_eq`)
prefix, or sometimes a `_perm` suffix for lemmas that _prove_ `perm_eq`
using a property when there is also a lemma _using_ `perm_eq` for the
same property. Lemmas that do not concern `perm_eq` do _not_ have
`perm` in their name.
- Change the definition of `permutations` for a time- and space-
back-to-front generation algorithm.
- Add frequency tally operations `tally`, `incr_tally`, `wf_tally` and
`tally_seq`, used by the improved `permutation` algorithm.
- add deprecated aliases for renamed lemmas
