Rename max_document_size to max_http_request_size

`max_document_size` is implemented as `max_http_request_size`. There was no
real check for document size. In some cases the implementation was close enough
of a proxy (PUT-ing and GET-ing single docs), but in some edge cases, like
_bulk_docs requests the discrepancy between request size and document size
could be rather large.

The section was changed accordingly from `couchdb` to `httpd`. `httpd` was
chosen as it applies to both clustered as well as local interface.

There is a parallel effort to implement an actual max_document_size check. The
set of commit should be merged close enough together to allow for a backwards
compatible transition.
