warning cleanup: signed/unsigned in ternaries.

This is the third round of an effort to enable GCC's -Wextra
option. Instances of signed/unsigned mismatch between
the branches of ternary conditionals are addressed.

* ffi.c (pad_retval): Add cast into the consequent of
the conditional so it yields size_t, like the alternative.

* lib.c (split_str_keep): Likewise.
(vector): Cast -1 to ucnum so it has the same type as the
alloc_plus opposite to it.

* parser.c (lino_getch): Add a cast to wint_t to match
return value and opposite WEOF operand.

* stream.c (generic_get_line): Likewise.

* sysif.c (c_time): Convert both consequent and alternative
to time_t to silence warning.
