From: Jeff King <peff@xxxxxxxx>
In the last commit we dropped support for curl < 7.11.1, let's
continue that and drop support for versions older than 7.16.0. This
allows us to get rid of some now-obsolete #ifdefs.
Choosing 7.16.0 is a somewhat arbitrary cutoff:
1. It came out in October of 2006, almost 15 years ago.
Besides being a nice round number, around 10 years is
a common end-of-life support period, even for conservative
distributions.
2. That version introduced the curl_multi interface, which
gives us a lot of bang for the buck in removing #ifdefs
RHEL 5 came with curl 7.15.5[1] (released in August 2006). RHEL 5's
extended life cycle program ended on 2020-11-30[1]. RHEL 6 comes with
curl 7.19.7 (released in November 2009), and RHEL 7 comes with
7.29.0 (released in February 2013).
