Noah Gold 8003bd6a5c Make gonet.PacketConn implement net.Conn.
gonet.PacketConn now implements net.Conn, allowing it to be returned from
net.Dial.Dialer functions.

Bhasker Hariharan 3e3a1ef9d6 Updates tcp_proxy to use an AF_PACKET and veth devices.
tcp_proxy now uses an AF_PACKET socket as the FD for netstack link layer
endpoint instead of a tap device. It also changes the link layer endpoint to use
PacketMMap dispatch instead of Readv. This reduces overall cpu and reflects the
current runsc setup which uses PacketMMap and also uses veth devices to receive
packets.

Also fixed a bug in gonet where Read() was not doing coalescing read and would
read small amounts at a time.

Adin Scannell 75cd70ecc9 Track paths and provide a rename hook.
This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.

Sepehr Raissian c17ea8c6e2 Block for link address resolution
Previously, if address resolution for UDP or Ping sockets required sending
packets using Write in Transport layer, Resolve would return ErrWouldBlock
and Write would return ErrNoLinkAddress. Meanwhile startAddressResolution
would run in background. Further calls to Write using same address would also
return ErrNoLinkAddress until resolution has been completed successfully.

Since Write is not allowed to block and System Calls need to be
interruptible in System Call layer, the caller to Write is responsible for
blocking upon return of ErrWouldBlock.

Now, when startAddressResolution is called a notification channel for
the completion of the address resolution is returned.
The channel will traverse up to the calling function of Write as well as
ErrNoLinkAddress. Once address resolution is complete (success or not) the
channel is closed. The caller would call Write again to send packets and
check if address resolution was compeleted successfully or not.
