Do some pedantic spring cleaning

- Use const in more places where it makes sense - not absolutely
  everywhere because it can get a bit annoying

- Make all the instruction search loops a bit more readable by casting
  the function pointer into a temporary variable to loop over

- Add a few more doc comments and fix a typo or two

- Make that RTTI thing flexibly-sized, finally

- Don't include gamedata.h in vcall.h for no reason; consequently
  include gamedata.h in a bunch of places where it was implictly pulled
  in before

- Fix dbg_toghidra() and ent_getedict() having mismatched return types
  between their headers and respective source files

- Remove that one broken, hacky, secret Portal non-feature that probably
  nobody even ended up using; it can be implemented properly later if
  required
