Log Message:
Update from 1.19.0 to 1.20.0.
Remove the needless patches, those been applied to upstream.

<ChangeLog>

*) Change: the PHP module is now initialized before chrooting; this
   enables loading all extensions from the host system.

*) Change: AVIF and APNG image formats added to the default MIME type
   list.

*) Change: functional tests migrated to the pytest framework.

*) Feature: the Python module now fully supports applications that use
   the ASGI 3.0 server interface.

*) Feature: the Python module now has a built-in WebSocket server
   implementation for applications, compatible with the HTTP & WebSocket
   ASGI Message Format 2.1 specification.

*) Feature: automatic mounting of an isolated "/tmp" file system into
   chrooted application environments.

*) Feature: the $host variable contains a normalized "Host" request
   value.

*) Feature: the "callable" option sets Python application callable
   names.

*) Feature: compatibility with PHP 8 RC 1. Thanks to Remi Collet.

*) Feature: the "automount" option in the "isolation" object allows to
   turn off the automatic mounting of language module dependencies.

*) Bugfix: "pass"-ing requests to upstreams from a route was broken; the
   bug had appeared in 1.19.0. Thanks to 洪志道 (Hong Zhi Dao) for
   discovering and fixing it.

*) Bugfix: the router process could crash during reconfiguration.

*) Bugfix: a memory leak occurring in the router process; the bug had
   appeared in 1.18.0.

*) Bugfix: the "!" (non-empty) pattern was matched incorrectly; the bug
   had appeared in 1.19.0.

*) Bugfix: fixed building on platforms without sendfile() support,
   notably NetBSD; the bug had appeared in 1.16.0.
