Use libcurl's high-level API functions to implement git-imap-send instead of the previous low-level OpenSSL-based functions. Since version 7.30.0, libcurl's API has been able to communicate with IMAP servers. Using those high-level functions instead of the current ones would reduce imap-send.c by some 1200 lines of code. For now, the old ones are wrapped in #ifdefs, and the new functions are enabled by make if curl's version is >= 7.35.0, from which version on curl's CURLOPT_LOGIN_OPTIONS (enabling IMAP authentication) parameter has been available. As I don't have access to that many IMAP servers, I haven't been able to test the new code with a wide variety of parameter combinations. I did test both secure and insecure (imaps:// and imap://) connections and values of "PLAIN" and "LOGIN" for the authMethod. Signed-off-by: Bernhard Reiter <ockham@xxxxxxxxx> --- I rebased the patch on the pu branch, hope that was the right thing to do.
