Don't let pipelining checks and keep-alive times interfere
with the timeouts computed for subsequent requests.  PR 56729.


With pipelined requests, the log_transaction hook is called when the request
is destroyed, which may happen after a subsequent request is to be handled on
the same connection.
Move the initialization of the "header" state into pre_read_request() instead,
and get rid of the racy log_trasaction hook.

This fixes issue resulting in setting of bad useragent_ip when internal
redirection has been generated as response to the request (typically as
result of "ErrorDocument 40x").

In this case, the original request has been handled by mod_remoteip and its
useragent_ip has been changed properly, but when internal redirection
to ErrorDocument has been generated later, the mod_remoteip's handler has been
executed again with *the same* c->client_addr as in the original request. If
c->client_addr IP is trusted, this results in bad useragent_ip being set.

When using r->useragent_addr as the root trusted address instead of
c->client_addr, the internal redirection uses the first non-trusted
IP in this particular case, so it won't change the r->useragent_ip during
the internal redirection to ErrorDocument.

Don't check LimitRequestBody when there is no (more) body.

This fixes an uninitialized use of 'totalread' in ap_http_filter() when either
the remaining or requested number of body bytes is zero, leading to an invalid
computation of bytes received.
