b9bf6e80f4 fix: io and os instead of deprecated ioutil 
Deprecated: As of Go 1.16, the same functionality is now provided by package io or package os, and those implementations should be preferred in new code. See the specific function documentation for details.

2332d9b7c1 Add local_addr configuration for doh-server (#39) 
* Add local_addr configuration for doh-server

This commit adds a `local_addr` string value to `doh-server.conf`, specifying the IP address and port from which outgoing calls to upstream DNS resolvers should originate. This value is set as the `udpClient`'s and `tcpClient`'s `Dialer.LocalAddr` when initializing a `NewServer`. If the value is left empty in `doh-server.conf`, it defaults to the first `listen` address (which in turn defaults to `"127.0.0.1:8053"`).

One use case for this would be if `doh-server` is proxying requests to a local DNS resolver (e.g. `unbound` or Pi-hole). Up to version 2.0.0, all DNS queries from `doh-server` are sent from `127.0.0.1` (even if the `listen` address is set to a different loopback IP address), making it hard to distinguish them from all other local DNS queries from the same machine in the query logs.

* Revert defaulting of local_addr to listen address

This commit reverts to the existing behavior when `conf.LocalAddr == ""`, i.e. letting `dns.Client` instantiate its own `Dialer` with the default local address.

* Fixup comment in configuration file

* Log errors from Dialer instantiation (e.g. if LocalAddr port is missing)

* Fixup other comment in configuration file

* Return error and log fatal
