[leszko]

This allows B to set separately:

• Max single ticket EV
• Max total EV for one payment

The context is that the current -maxTicketEV flag set in B has 2 purposes:

• Sets the maximum -ticketEV accepted from O
• Sets the maximum total ticket EV sent with one segment

So, we split it into 2 flags. The broader context is that the current ticket EV is usually set to a too-high value, which means overpaying by B for short videos.
