'virtio_transport_send_credit_update()' has some extra args:
1) 'type' may be set in 'virtio_transport_send_pkt_info()' using type
of socket.
2) This function is static and 'hdr' arg was always NULL.

This moves passing type of packet from 'info' srtucture to send
function. There is no sense to set type of packet which differs
from type of socket, and since at current time only stream type
is supported, so force to use this type.

This adds transport callback and it's logic for SEQPACKET dequeue.
Callback fetches RW packets from rx queue of socket until whole record
is copied(if user's buffer is full, user is not woken up). This is done
to not stall sender, because if we wake up user and it leaves syscall,
nobody will send c
This adds rest of logic for SEQPACKET:
1) SEQPACKET specific functions which send SEQ_BEGIN/SEQ_END.
Note that both functions may sleep to wait enough space for
SEQPACKET header.
2) SEQ_BEGIN/SEQ_END in TAP packet capture.
3) Send SHUTDOWN on socket close for SEQPACKET type.
4) Set SEQPACKET
This adds transport callback which tries to fetch record begin marker
from socket's rx queue. It is called from af_vsock.c before reading data
packets of record.

This modifies current receive logic for SEQPACKET support:
1) Inserts 'SEQ_BEGIN' packet to socket's rx queue.
2) Inserts 'RW' packet to socket's rx queue, but without merging with
buffer of last packet in queue.
3) Performs check for packet and socket types on receive(if mismatch,
then reset

When link speed is not 100 Mbps, port transmit rate and speed divider
are set to 8 and 100 respectively. These values are incorrect for
CBS idleslope and sendslope HW values calculation if the link speed is
not 1 Gbps.

This adds two tests of SOCK_SEQPACKET socket: both transfer data and
then test MSG_EOR and MSG_TRUNC flags. Cases for connect(), bind(),
etc. are not tested, because it is same as for stream socket.
