tw_fprint_binary_array

Printing the array "hello world! I'm happy to be here" would produce:

| 68 65 6c 6c 6f 20 77 6f 72 6c 64 21 20 49 27 6d | hello world! I'm | 20 68 61 70 70 79 20 74 6f 20 62 65 20 68 65 72 | happy to be her | 65 | e

tw_output()

int tw_output	(	tw_lp *	lp,
		const char *	fmt,
			... )

Rollback-aware printf, i.e. if the event gets rolled back, undo the printf. We can'd do that of course so we store the message in a buffer until GVT.
