MINOR: hlua: Add a flag on the lua txn to know in which context it can be used
When a lua action or a lua sample fetch is called, a lua transaction is
created. It is an entry in the stack containing the class TXN. Thanks to it, we
can know the direction (request or response) of the call. But, for some
functions, it is also necessary to know if the buffer is "HTTP ready" for the
given direction. "HTTP ready" means there is a valid HTTP message in the
channel's buffer. So, when a lua action or a lua sample fetch is called, the
flag HLUA_TXN_HTTP_RDY is set if it is appropriate.
