[PATCH v7 0/2] http-backend: respect CONTENT_LENGTH as specified by rfc3875

It's been time. Thank you for parience.

Changes:

* did most of the changes proposed
* rebase to newer master (latest conflicting change is addition of combined test helper)
* make tests which cover, hopefully, all cases.
* handle incorectly truncated input also in receive-pack. Considering the complications
  pointed out by Jeff, it just filters the input in the frontend process. I hope it
  is acceptable thing to do.
