vhost: get device once
Invoke get_device() at the beginning of vhost_user_msg_handler, so that
we could check the return value once. Which could save tons of duplicate
get-and-check device.

vhost: fold common message handlers
Due to history reason (that we have 2 vhost implementations), some
messages are handled in two calls: vhost specific implementation
handles it first and then invoke the common one to do another handling.
We have one implementation only now, we could write one method for
each message. Here fold those common handles to corresponding vhost
user handler.

vhost: refactor code structure
The code structure is a bit messy now. For example, vhost-user message
handling is spread to three different files:
vhost-net-user.c virtio-net.c virtio-net-user.c
Where, vhost-net-user.c is the entrance to handle all those messages
and then invoke the right method for a specific message. Some of them
are stored at virtio-net.c, while others are stored at virtio-net-user.c.
The truth is all of them should be in one file, vhost_user.c.
So this patch refactors the source code structure: mainly on renaming
files and moving code from one file to another file that is more suitable
for storing it. Thus, no functional changes are made.
After the refactor, the code structure becomes to:
- socket.c handles all vhost-user socket file related stuff, such
as, socket file creation for server mode, reconnection
for client mode.
- vhost.c mainly on stuff like vhost device creation/destroy/reset.
Most of the vhost API implementation are there, too.
- vhost_user.c all stuff about vhost-user messages handling goes there.
- virtio_net.c all stuff about virtio-net should go there. It has virtio
net Rx/Tx implementation only so far: it's just a rename
from vhost_rxtx.c

examples/vhost: remove VLAN strip option
When VMDQ is enabled, different NICs have different behaviors for
disabling VLAN strip. In detail, i40e only enables/disables it of
PF's main vsi; fm10k cannot disable VLAN strip, etc. We now remove
this option, --vlan-strip, to reduce any confusion. And now, VLAN
strip will be enabled and cannot be disabled.
