Security issues fixed:

- CVE-2016-8743: Fixed liberal whitespace interpretation accepted from requests
 and sent in response lines and headers. Accepting these different behaviors
 represented a security concern when httpd participates in any chain of
 proxies or interacts with back-end application servers, either through
 mod_proxy or using conventional CGI mechanisms, and may result in request
 smuggling, response splitting and cache pollution. (bsc#1016715)
- CVE-2016-4975: Fixed possible CRLF injection allowing HTTP response splitting
 attacks for sites which use mod_userdir. This issue was mitigated by changes
 which prohibit CR or LF injection into the 'Location' or other outbound
 header key or value. (bsc#1104826)");
