init: fix sysfs mount arguments
It is not good idea to pass empty 'source' argument to mount(2) because libmount complains about incorrect /proc/self/mountinfo structure. This affects many applications such as findmnt, umount and etc.
Let's add fake source argument to sysfs mount command as we do with all other filesystems.

Add the tiny x86/init.S which just mounts /host and execs /virt/init.
NOTE: of course, the usage of CONFIG_GUEST_PRE_INIT is ugly, we need to cleanup this code. But I'd prefer to do this on top of this minimal/simple change. And I think this needs cleanups in any case, for example I think lkvm shouldn't abuse the "init=" kernel parameter at all.

guest/init: update reboot() call
The reboot() call that guest/init used was an older version, the manpage talks about libc4 and libc5. Update it to the current version exported by glibc by using the right include file and adjusting the parameter. This also fixed GCC 5.1.0 compile, because linux/reboot.h misses the actual prototype.

commit eaf720b285947a6f4e29174d0eba1899de31d8ab kvm tools: Split custom rootfs init into two stages
to address the outdated init binary issue.
Currenly, init binary is embedded in lkvm binary and generated on the fly. So there is no need to split the init process.
This makes 1) the size of lkvm binary smaller becasue only one statically linked init binary. 2) the init process simpler and cleaner.

kvm tools: Split custom rootfs init into two stages
Currently custom rootfs init is built along with the main KVM tools executable and is copied into custom rootfs directories when they are created with 'kvm setup'. The problem there is that if the init code changes, they have to be manually copied to custom rootfs directories.
Instead, this patch splits init process into two parts. One part that simply handles mounts, and passes it to stage 2 of the init.
Stage 2 really sits along in the code tree, and does all the heavy lifting.
This allows us to make init changes in the code tree and have it automatically be updated in custom rootfs guests without having to copy files over manua

kvm tools: Use kernel dhcp for network autoconfiguration
This patch removes the manual/usermode dhcp client configuration and instead uses the DHCP client built within the kernel.
Since this client is tightly integrated with NFS (if NFS config is set), we will add a specific NFS root addr in our DHCP offer to point it to a non existent address so that we won't hang trying to poke it for our root.

kvm tools: Introduce 'kvm setup' command
This patch implements 'kvm setup' command that can be used to setup a guest filesystem that shares system libraries and binaries from host filesystem in read-only mode.
You can setup a new shared rootfs guest with:
./kvm setup -n default
and launch it with:
./kvm run --9p /,hostfs -p "init=virt/init" -d ~/.kvm-tools/default/
We want to teach 'kvm run' to be able to launch guest filesystems by name in the future. Furthermore, 'kvm run' should setup a 'default' filesystem and use it by default unless the user specifies otherwise.
