Pascal Muller 04f1e49459 http: optionally send SSL client certificate
This adds support for a new http.sslAutoClientCert config value.

In cURL 7.77 or later the schannel backend does not automatically send
client certificates from the Windows Certificate Store anymore.

This config value is only used if http.sslBackend is set to "schannel",
and can be used to opt in to the old behavior and force cURL to send
client certificates.

This fixes https://github.com/git-for-windows/git/issues/3292

/**
* This header centralizes the declaration of our libcurl dependencies
* to make it easy to discover the oldest versions we support, and to
* inform decisions about removing support for older libcurl in the
* future.
*
* The oldest supported version of curl is documented in the "INSTALL"
* document.
*
* The source of truth for what versions have which symbols is
* https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions;
* the release dates are taken from curl.git (at
* https://github.com/curl/curl/).
*
* For each X symbol we need from curl we define our own
* GIT_CURL_HAVE_X. If multiple similar symbols with the same prefix
* were defined in the same version we pick one and check for that name.
*
* We may also define a missing CURL_* symbol to its known value, if
* doing so is sufficient to add support for it to older versions that
* don't have it.
*
* Keep any symbols in date order of when their support was
* introduced, oldest first, in the official version of cURL library.
