commit 141a8e702c0d145de85abc7fd1f9d11363fa24a7
Author: Evgeny Grin (Karlson2k) <k2k@narod.ru>
AuthorDate: Sun Dec 12 17:31:39 2021 +0300

    test_https_time_out: additional fixes
    
    Fixed possible abort on SIGPIPE.
    Avoid meaningless test results reports (-1 was mapped to unsigned value).
    Check GnuTLS functions results.
    Correctly initialize GnuTLS session.
