When re-reading upstream servers from /etc/resolv.conf or other sources that can change dnsmasq tries to avoid memory fragmentation by re-using existing records that are being re-read unchanged. This involves seaching all the server records for each new one installed. During startup this search is pointless, and can cause long start times with thousands of --server options because the work needed is O(n^2). Handle this case more intelligently. Thanks to Ye Zhou for spotting the problem and an initial patch. Signed-off-by: DL6ER <dl6er@dl6er.de>

What does this implement/fix?
This adds the two most recent changes. One vastly improves the speed of edge-case configurations where users have many (think thousands of)
server=...config lines. The other one fixes handling of unsupported crypto algorithms (there are none to date so that shouldn't have a practival influence).Related issue or feature (if applicable): N/A
