> This adds an option to test the msg_pull_data helper. This
> uses two options txmsg_start and txmsg_end to let the user
> specify start and end bytes to pull.
> 
> The options can be used with txmsg_apply, txmsg_cork options
> as well as with any of the basic tests, txmsg, txmsg_redir and
> txmsg_drop (plus noisy variants) to run pull_data inline with
> those tests. By giving user direct control over the variables
> we can easily do negative testing as well as positive tests.
