We forgot to update the License section in the readme
template. So, let's specify that vsock crate is licensed
under Apache 2.0 OR BSD-3-Clause.

As pointed out in the issue #232, vsock tests fail randomly.
From an initial analysis, it appears that using `--test-threads=1`
never happens, but using a value greater than 1, the tests fails
after a while and almost always with the creation of UDS,
or EpollFD, or on epoll_ctl.
There should be something wrong with FDs when there are multiple
threads running tests (not sure if related to O_CLOEXEC).
This is just a workaround, we will revert this commit when we
identify the root cause.

In several places the "vsock_" prefix doesn't add much and makes
names longer, let's remove it where it's not needed.

This is a binary crate and most of the types shouldn't be visible
out of this crate. Change also documentation with ///.
If we would like to export some types as part of a library in the
future, we will adjust the visibility accordingly.

Add several tests to get good coverage. Unfortunately,
it's a lot of new code and not easy to test everything.
We may add more mocks and tests in the future.

VIRTIO spec defines `guest_cid` in LE byte order.
Let's introduce VirtioVsockConfig based on the virtio-spec 1.2.
For now it contains only `guest_cid`, but in the future it could
contain other fields.
Let's also handle correctly `offset` and `size`, returning an empty
Vec if they are not valid.

If we don't remove any bytes from the buffer, it's useless to

Instead of panic if the local peer doesn't send "connect PORT\n"
correctly, let's print an error, ignoring the command.
Print an error message also when allocating local port fails.

Replace our VsockPacket with the new one implemented in the
virtio-vsock crate.
Based on Alex Bennée and Laura Loghin commit:
https://github.com/stsquad/vhost-device/commit/6752266608dd
To achieve this the following changes where made:
- deleted the internal packet.rs
- convert the send_pkt/recv_pkt helpers to be BitmapSlice aware
- update push from LocalTxBuf
- tweak a few API calls due to minor diffs
Fixed tests and moved some helpers from the removed
vsock/src/packet.rs file.

This commit introduces a vhost-user-vsock device that enables
communicaton between an application running in the guest i.e
inside a VM and an application running on the host i.e outside
the VM. The device exposes unix sockets to which the VMM and
host-side applications connect to. Applications in the guest
communicate over VM sockets. Applicaitons on the host connect to
the unix socket i.e communicate over AF_UNIX sockets.
