The first load of the last sequence via `firstMatching` or `firstMatchingMulti` will still continue to flag `expireOk`, as though we're optimising for the linear scan case, but if it becomes apparent that we are continuously reloading the same last sequence over and over again in this way, don't set `expireOk` or we'll just keep expiring and reloading the cache each time.

Setting the "hop" header for each gateway could cause header corruption. This is now fixed. A test dealing with gateway has been improved to include more than one gateway, which would have demonstrated the issue. The test now passes and ensures that the hop is different per gateway.

Saw the test TestConfigCheck flap. The reason is that the proxy validation was done when parsing the "proxy" field, but there was no guarantee that this field would be parsed after "urls", which may lead to validation being successful (because there was no URLs added yet). Move the check after all fields have been parsed for a given remote. Relates to #7242 Signed-off-by: Ivan Kozlovic <ivan@synadia.com>
