[PATCH 1/2] http.c: fix compiling with libcurl 7.9.2

[Mark Lodato <lodatom@gmail.com>]

Change the minimimum required libcurl version for the http.sslKey option
to 7.9.3.  Previously, preprocessor macros checked for >= 7.9.2, which
is incorrect because CURLOPT_SSLKEY was introduced in 7.9.3.  This now
allows git to compile with libcurl 7.9.2.

This patch series is independent of my other password prompting patch
series, and is based off 'next', which includes Tay Ray Chuan's recent
http changes.

Note that git still does not compile on libcurl before 7.9.1 or below,
since CURLOPT_FTP_USE_EPSV (http.c:236) is defined in libcurl 7.9.2.

One question: In http.c, there are unnecessary #if LIBCURL_VERSION_NUM's
surrounding the global variable declarations, in http_options(), and in
http_init().  Is there a reason why these exist?  If not, I think
removing them would make the code easier to read.

Any feedback or suggestions are appreciated!
Mark
