Add a patch for Squid bug #1814, see <http://www.squid-cache.org/bugs/show_bug.cgi?id=1814>.

The patchset is a slightly modified version of the Squid patchset 11375.

Notes:
Since this patch conflicts with the ICAP patchset and only affects
non-default configurations that have been compiled using the
WITH_SQUID_SSL configuration option, apply the patch only when this
option is enabled. Set IGNORE when both WITH_SQUID_SSL and
WITH_SQUID_ICAP are defined.

PR:		112054
