BUG/MINOR: http-ana: Properly catch aborts during the payload forwarding

Browse source 
When no data filter are registered on a channel, if the message length is known,
the HTTP payload is infinitely forwarded to save calls to process_stream(). When
we finally fall back again in XFER_BODY analyzers, we detect the end of the
message by checking channel flags. If CF_EOI or CF_SHUTR is set, we switch the
message in DONE state. For CF_EOI, it is relevant. But not for CF_SHUTR. a
shutdown for reads without the end of input must be interpreted as an abort for
messages with a known length.

Because of this bug, some aborts are not properly handled and reported. Instead,
we interpret it as a legitimate shutdown.

This patch must be backported to 2.0.
