BUG/MEDIUM: http: unbreak uri/header/url_param hashing
Vedran Furac reported that "balance uri" doesn't work anymore in recent
1.7-dev versions. Dragan Dosen found that the first faulty commit was
dbe34eb ("MEDIUM: filters/http: Move body parsing of HTTP messages in
dedicated functions"), merged in 1.7-dev2.
After this patch, the hashing is performed on uninitialized data,
indicating that the buffer is not correctly rewound. In fact, all forms
of content-based hashing are broken since the commit above. Upon code
inspection, it appears that the new functions http_msg_forward_chunked_body()
and http_msg_forward_body() forget to rewind the buffer in the success
case, when the parser changes to state HTTP_MSG_DONE. The rewinding code
was reinserted in both functions and the fix was confirmed by two test,
with and without chunking.
No backport it needed.
