As with the previous two commits, we should be passing long integers, not regular ones, to curl_easy_setopt(), and compiling against curl 8.14 loudly complains if we don't.
This patch catches the remaining cases, which are ones where we pass curl's own symbolic constants. We'll cast them to long manually in each call.
It seems kind of weird to me that curl doesn't define these constants as longs, since the point of them is to pass to curl_easy_setopt(). But in the curl documentation and examples, they clearly show casting them as part of the setopt calls. It may be that there is some reason not to push the type into the macro, like backwards compatibility. I didn't dig, as it doesn't really matter: we have to follow what existing curl versions ask for anyway.
