Build Updates

This is a series of updates to make building magic far less of a headache:

* Drop `csh`/`tcsh` dependency and detection from `./configure`.
* Rewrite makedbh in Python.
* Rewrite printmans in POSIX sh.
* Stop deleting Depend before every compile (which causes some files to recompile and thus increases recompile times significantly)
* Add Depend to CLEANS in scripts/defs.mak.in
* Turn POSIX suffix rule in magic/rules.mak to a pattern rule with proper prerequisites
