BUG/MEDIUM: lua: Forbid HTTP applets from being called from tcp rulesets

HTTP applets request requires everything initilized by
"http_process_request" (analyzer flag AN_REQ_HTTP_INNER).
The applet will be immediately initilized, but its before
the call of this analyzer.

Due to this problem HTTP applets could be called with uncompletely
initialized http_txn.

This fix must be backported to 1.6.
