Fix retry backoff time parsed from Retry-After header when given in the HTTP date format. The HTTP date was parsed as the local timezone rather than accounting for the timezone in the HTTP date (typically UTC) (#1932, #1935, #1938, #1949)

Fix issue where an error would be raised when the SSLKEYLOGFILE environment variable was set to the empty string. Now SSLContext.keylog_file is not set in this situation (#2016)
