Default to the same build behavior, but allow a go build tag to disable
building of the btrfs graphdriver
go build -tags no_btrfs' ...
$ go build
$ objdump -S docker | grep btrfs | wc -l

$ go build -tags no_btrfs
$ objdump -S docker | grep btrfs | wc -l

Enable build tags for all the graphdrivers to be excludable.
As an example:
```
$ go build
$ ls -l docker
-rwxr-xr-x 1 vbatts vbatts 18400158 Mar 14 14:22 docker*
$ go build -tags "exclude_graphdriver_aufs exclude_graphdriver_vfs exclude_graphdriver_devicemapper"
$ ls -l docker
-rwxr-xr-x 1 vbatts vbatts 17467068 Mar 14 14:22 docker*
```

Since we're not not mounting anything but the base filesystem outside
the container we no longer need the separate bind mount at
/var/lib/docker/container/$id/root in order to see the base filesystem
without extra mounts. So, we drop this and mount (again) the container
root directly at the real basefs mountpoint.

This moves the bind mounts like /.dockerinit, /etc/hostname, volumes,
etc into the container namespace, by setting them up using lxc.
This is useful to avoid littering the global namespace with a lot of
mounts that are internal to each container and are not generally
needed on the outside. In particular, it seems that having a lot of
mounts is problematic wrt scaling to a lot of containers on systems
where the root filesystem is mounted --rshared.
Note that the "private" option is only supported by the native driver, as
lxc doesn't support setting this. This is not a huge problem, but it does
mean that some mounts are unnecessarily shared inside the container if you're
using the lxc driver.

This can't be in execdriver (dependency loop) but should not be
hardcoded inside runtime.go either. So we put it in a subpackage.
