Add a "BYTES_ARE_IN_FRAME()" macro, to test whether there are a
specified number of bytes of captured data in the frame at the specified
offset, and a "IS_DATA_IN_FRAME()" macro, to test whether there are any
bytes of captured data in the frame at the specified offset, and convert
some bounds checks to use them.
Add a dissector for the Internet Printing Protocol.
