Merge r1729929 from trunk:

Introduce an ap_get_useragent_host() accessor to replace the old
ap_get_remote_host() in most applications, but preserve the original
behavior for all ap_get_remote_host() consumers (mostly, because we
don't have the request_rec in the first place, and also to avoid any
unintended consequences).

This accessor continues to store the remote_host of connection based
uesr agents within the conn_rec for optimization.  Only where some
other module modifies the useragent_addr will we perform a per-request
query of the remote_host.

(Fixed compilation issues noted by Ranier, applies to 2.4.x trunk,
modulo CHANGES and ap_mmn.h)

from feedback, assume all parameters to SetHandler are expressions.

I couldnt come up with a plausible handler name that was an
invalid expression.

Merge r1725325 from trunk:

* Since r1724820 two modules, mod_http2 and mod_ssl, call APACHE_CHECK_OPENSSL,
  with mod_http2 doing it first. Because the result of APACHE_CHECK_OPENSSL
  is cached this causes MOD_LDFLAGS and MOD_CFLAGS to remain unset for mod_ssl
  which in turn causes it not to be linked against Openssl which means that
  mod_ssl cannot be loaded if the Openssl libs haven't been loaded by other means
  already.
  Fix this by caching the values for MOD_LDFLAGS and MOD_CFLAGS created during
  the first run and set them in the cached case.
