I've fixed these issues in the branch now.

I can reduce the number of casts in shell/bsescm* by changing the signature,
however there is quite a bit of C code that either will not compile at all or
will compile with warnings if I do this (for instance in sfi/sfiglue.c or the
generated beast-gtk/bstgenapi.c), so overall a lot of new casts need to be
added elsewhere. I'd suggest to delay this change until more of the remaining
code is already C++ified.
