Change subject: Support CIDR ranges in $wgSquidServersNoPurge
......................................................................
Support CIDR ranges in $wgSquidServersNoPurge
Use IP::isInRange() in wfIsConfiguredProxy() to allow matching against
CIDR entries in $wgSquidServersNoPurge. This will allow maintainers of
large networks to whitelist contiguous blocks of IPv4 and/or IPv6
addresses as trusted X-Forwarded-For providers.
This change also makes a small change to
WebRequestTest::testGetIpLackOfRemoteAddrThrowAnException() which was
failing under some configurations due to non-default globals
configuration.
