tap: Implement tap_send() "slow path" in terms of fast path
Most times we send frames to the guest it goes via tap_send_frames().
However "slow path" protocols - ARP, ICMP, ICMPv6, DHCP and DHCPv6 - go
via tap_send().
As well as being a semantic duplication, tap_send() contains at least one
serious problem: it doesn't properly handle short sends, which can be fatal
on the qemu socket connection, since frame boundaries will get out of sync.
Rewrite tap_send() to call tap_send_frames(). While we're there, rename it
tap_send_single() for clarity.
