Req_body functions (length, hash, regex)

please find patch attached.
This is a proposed solution for 3 req.body functions: len_req_body,
hash_req_body and rematch_req_body.
The idea is to iterate over the request body, wrap it into a blob (I
have to thank Nils for this because I took the idea from the vmod he
wrote a couple of weeks ago) and use this blob for operation such as
hashing on it or regex matching.
*len_req_body: check if the req.body has been buffered, if so then we
return the number of consumed bytes.
*hash_req_body: first the req.body is collected in a blob, then we
hash on this (I had to implement a new function for hashing on binary
*rematch_req_body: using a priv_call the regular expression given as
parameter is compiled just once, then we use VRE_exec on the req.body
blob to check if there's a regex match.
Comments much appreciated.
