This reverts commit d89a95a48c as,
finally, it's not worth trying to use UTL typemaps from C: this required
bad hacks for std::vector and would be even worse for std::map, so don't
bother with them and just correct the "poor" C typemaps to be slightly
less poor and use them instead.
At the very least, this gives us a working vector<bool> and allows
"li_std_vector" unit test to pass. It is also just nice to reuse the existing
typemaps instead of having another copy of them.
As C doesn't have UTL, some parts of std_vector.i had to be excluded from it
however.
