Log:
Drop workarounds for potential guile issues with long long

- The workarounds for long long were added more than 12
years back (pre guile 1.6). One would reasonably assume this issue would
have been fixed by now.
- But more importantly, we can guarantee a proper 64 type
conversion by replacing scm_to/from_long_long with scm_to/from_int64
which is always 64bit, just as gint64

I have chosen nonetheless to keep this change in a separate commit so
it's easier to track if some obscure platform still manages to screw
this up.
