Rename the original VhostUserSlaveReqHandler trait as
VhostUserSlaveReqHandlerMut, and add another VhostUserSlaveReqHandler

This also help to simplify caller implementations.

This adds the missing part of supporting virtiofs dax on the slave end,
that is, receiving a socket pair fd from the master end to set up a
communication channel for sending setupmapping & removemapping messages.

The VhostUserConfig carries a message with a payload, the contents of
which depend on the kind of device being emulated.
With this change, we calculate the offset of the payload within the
message, check its size corresponds to the expected one, and pass it
to the backend as a reference to a slice adjusted to the payload
dimensions.
The backend will be responsible of validating the payload, as it's the
one aware of its expected contents.
