[PATCH v2 0/3] Allow choosing the SSL backend cURL uses (plus related patches)

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

This topic branch brings support for choosing cURL's SSL backend (a feature
developed in Git for Windows' context) at runtime via http.sslBackend, and
two more patches that are related (and only of interest for Windows users).

Changes since v1:

 * Reworded the commit message of v1's patch 2/3, to talk about the original
   design instead of "an earlier iteration" that was never contributed to
   the Git mailing list.
 * Changed the confusing >= 7.44.0 to < 7.44.0.

Note: I had prepared 
https://github.com/dscho/git/commit/81e8c9a4006c919747a0b6a287f28f25799fcaf4
, intended to be included in v2, but Junio came up with 
https://public-inbox.org/git/xmqqsh0uln5c.fsf_-_@gitster-ct.c.googlers.com/ 
in the meantime, which I like better.
