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

# Introduction

This module writes out a traceback to a file when a chosen signal (by default
`SIGUSR1`) is received. It can be useful to diagnose cases where Prosody is
unresponsive.

# Configuration

`debug_traceback_filename`
:   The name of the file to write the traceback to. Some variables
    are supported, see [mod_log_ringbuffer] docs for more info. Defaults
    to `{paths.data}/traceback-{pid}-{count}.log`.

`debug_traceback_signal`
:   The name of the signal to listen for. Defaults to `SIGUSR1`.

# Compatibility

Prosody 0.12 or later.
