A nearby thread raised the question of whether we can rely on a version
of libcurl that contains a particular feature. The version in question
is curl 7.11.1, which came out in March 2004.
My feeling is that this is old enough to stop caring about. Which means
we can drop some of the #ifdefs that clutter the HTTP code (and there's
a patch at the end of this mail dropping support for everything older
than 7.11.1). But that made wonder: how old is too old? I think it's
nice that we don't force people to upgrade to the latest version of
curl. But at some point, if you are running a 13-year-old version of
libcurl, how likely are you to run a brand new version of Git? :)
If we declared 7.16.0 as a cutoff, we could unconditionally define
USE_CURL_MULTI, which gets rid of quite a few messy ifdefs.
