A Unix domain socket is limited to 107 usable bytes on Linux. However,
not all code creating socket paths was checking for this limits.
Created a new `utils.BuildSocketPath()` function (with tests) to
encapsulate the logic and updated all code creating sockets to use it.
Fixes#268.

* Move makeNameID() func to virtcontainers/utils file as it's a generic
function for making name and ID.
* Move bindDevicetoVFIO() and bindDevicetoHost() to vfio driver package.

This is done for decoupling device management part from other parts.
It seperate device.go to several dirs and files:
```
virtcontainers/device
├── api
│ └── interface.go
├── config
│ └── config.go
├── drivers
│ ├── block.go
│ ├── generic.go
│ ├── utils.go
│ ├── vfio.go
│ ├── vhost_user_blk.go
│ ├── vhost_user.go
│ ├── vhost_user_net.go
│ └── vhost_user_scsi.go
└── manager
├── manager.go
└── utils.go
```
* `api` contains interface definition of device management, so upper level caller
should import and use the interface, and lower level should implement the interface.
it's bridge to device drivers and callers.
* `config` contains structed exported data.
* `drivers` contains specific device drivers including block, vfio and vhost user
devices.
* `manager` exposes an external management package with a `DeviceManager`.

When imported, the vc files carried in the 'full style' apache
license text, but the standard for kata is to use SPDX style.
Update the relevant files to SPDX.

Since Go 1.8 users no longer need to have GOPATH set in their environment
for the Go tool chain to work. If GOPATH is set, Go will use it. Otherwise
it defaults to ~/go on linux. As most users store their code in ~/go, they
don't bother setting GOPATH any more. virtcontainers-setup.sh, in its
current form, fails for those users, as it requires GOPATH to be set.
This commit fixes the issue by calling go env "GOPATH" to determine the
correct location of the user's go code. go env "GOPATH" will always
return the correct location, whether GOPATH is set, or not.

Some virtcontainers pieces of code are importing virtcontainers
packages. We need to change those paths to point at
kata-containers/runtime/virtcontainers
