Fixes the following security vulnerabilities:
*) SECURITY: CVE-2019-0197 (cve.mitre.org)
mod_http2: fixes a possible crash when HTTP/2 was enabled for a http:
host or H2Upgrade was enabled for h2 on a https: host. An Upgrade
request from http/1.1 to http/2 that was not the first request on a
connection could lead to a misconfiguration and crash. Servers that
never enabled the h2 protocol or only enabled it for https: and
did not set "H2Upgrade on" are unaffected by this issue.

*) SECURITY: CVE-2019-0196 (cve.mitre.org)
mod_http2: using fuzzed network input, the http/2 request
handling could be made to access freed memory in string
comparision when determining the method of a request and
thus process the request incorrectly. [Stefan Eissing]
*) SECURITY: CVE-2019-0211 (cve.mitre.org)
MPMs unix: Fix a local priviledge escalation vulnerability by not
maintaining each child's listener bucket number in the scoreboard,
preventing unprivileged code like scripts run by/on the server (e.g. via
mod_php) from modifying it persistently to abuse the priviledged main
process. [Charles Fol <folcharles gmail.com>, Yann Ylavic]
