On the trunk:

mod_http2: connection IO event handling reworked. Instead of reacting on 
     incoming bytes, the state machine now acts on incoming frames that are 
     affecting it. This reduces state transitions.

* mod_proxy: Remove load order and link dependency between mod_lbmethod_*
  modules and mod_proxy by providing mod_proxy's ap_proxy_balancer_get_best_worker
  as an optional function.

PR: 62557


* Remove invalid copy and paste comments

* Always retrieve conditional function. static variable might contain garbage if module was reloaded in a static build.

* Add missing log numbers

* ap_proxy_balancer_get_best_worker cannot be exported and used as an optional
  function at the same time. So rename ap_proxy_balancer_get_best_worker to
  proxy_balancer_get_best_worker and make it static which is then used as an
  optional function and recreate ap_proxy_balancer_get_best_worker as an
  exported thin wrapper of proxy_balancer_get_best_worker.

mpm_winnt: Factor out a helper function to parse the type of an accept
filter and use an appropriate enum for it.

This makes the code in winnt_accept() a bit easier to follow.  As a minor
side effect, it also fixes a small bug where the "unrecognized AcceptFilter
'%s'" log entry would always contain "none" instead of the actually
unrecognized kind of the accept filter.


mpm_winnt: Fix typo in the logged message in winnt_get_connection().


mpm_winnt: Following up on r1801144, use the new accept_filter_e enum
values in a couple of missed places in winnt_accept().
