Release v0.7.5.

This release contains a few fixes regarding cancellation of operations, and an
experimental feature to use DNS over HTTPS (DoH) in Origin requests.

Features:

  - Experimental support for resolving names using DNS over HTTPS (DoH) for
    the Origin request mechanism.  To enable it, you must provide the client
    with an `--origin-doh-base` option and give it a DoH base URL argument
    (like `https://mozilla.cloudflare-dns.com/dns-query` as used by Mozilla,
    more options [here](https://github.com/curl/curl/wiki/DNS-over-HTTPS)).

    DoH requests are handled internally as normal requests (respecting
    public/private browsing mode), and responses may be shared to the
    distributed cache.

    The feature is still slow since no private caching is used, so each
    requested URL triggers a full DoH request.

Bugfixes:

  - Fix checks for cancellation in several places (SSL client handshake,
    session flush, timeouts, fresh injection).
  - Check for errors after performing `CONNECT` to Proxy.
  - Fix case comparison of `X-Ouinet-Private` header values.
