d69f875261 - Set max-udp-size default to 1232. This is the same default value as
the default value for edns-buffer-size. It restricts client edns
  buffer size choices, and makes unbound behave similar to other DNS
  resolvers. The new choice, down from 4096 means it is harder to get
  large responses from Unbound. Thanks to Xiang Li, from NISL Lab,
  Tsinghua University.

75f3fbdd65 Downstream DNS Cookies a la RFC7873 and RFC9018
Create server cookies for clients that send client cookies.
Needs to be turned on in the config file with:

	answer-cookie: yes

A cookie-secret can be configured for anycast setups.
Also adds an access control list that will allow queries with
either a valid cookie or over a stateful transport.

0abfddd279 Allow using system certificates not only on Windows
OpenSSL has a way to load default file. That file might contain usable
certificates to verify common connections. Allow similar trust as on
windows and leave it on openssl package to provide sane defaults.

Also provide use-system-cert alias, because it is not windows specific
anymore.

d4314cad33 Make VAL_MAX_RESTART_COUNT configurable.
unbound tries very hard (up to 6 authoritative servers) to find a
validating answer. This is not always desirable, for example on high
latency links.

TCP connections to authority servers.
