mod_unified_push: Allow additional CORS headers for unified push (fixes #1985) - Request header "TTL" is mandated by the HTTP Push specification RFC 8030: https://datatracker.ietf.org/doc/html/rfc8030#section-5 - Firefox sends "Content-Encoding" with a HTTP form submission, so it is required when using the Unified Push testing tool at https://unifiedpush.org/test_wp.html (with the full URL being delivered by the UP-Example Android app) Adding both headers makes the Unified Push testing tool work from the browser. Resolves: https://issues.prosody.im/1985

summary: Workaround for Dialback with some servers that violate RFC 6120
...

This module provides a workaround for servers that do not set the `to`
attribute on stream headers, which is required per [RFC6120]:

> ## 4.7.2. to
> 
> For initial stream headers in both client-to-server and
> server-to-server communication, the initiating entity MUST include the
> 'to' attribute and MUST set its value to a domainpart that the
> initiating entity knows or expects the receiving entity to service.

As a side effect of [this issue](https://prosody.im/issues/issue/285),
Prosody 0.10 will be unable to do [Dialback][xep220] with servers that
don't follow this.

# Known servers affected
