The UUID has several usages before:
1, For HV to identify the static VM configuration of post-launched VM.
2, Seed virtualization.
3, Slightly prevent launching malicous VM from SOS as lack of secure
boot.
The UUID is confused to user, user don't understand what it is. And user
don't know where to get/apply the UUID. The worst experience is user
can't launch any VMs w/o re-compile the hv. Everything needs to be
static decided in building phase.
Now we decide to remove UUID and split each usage. For 1st usage, use
vmname as the identifier of static VM configuration. For 2nd one, we
will use --vseed as the new parameter. For 3rd one, will pretect by
SOS's dm-verity.
This patch will remove the UUID parameter and support 1st&3rd usages
from DM part. For 2nd usage, another patch will be submitted later.

Users of pthread_cond_wait() should take care of spurious wakeups and it
is usually used in conjunction with a predicate. Not doing so can result
in unintended behavior. For example:
virtio_net_tx_thread():
entry -> pthread_cond_wait() -> spurious wakeup ->
vq_clear_used_ring_flags() -> segfault (vq->used uninitialized)
tpm_crb_request_deliver():
entry -> pthread_cond_wait() -> spurious wakeup ->
swtpm_handle_request() called needlessly
virtio_rnd_get_entropy():
entry -> pthread_cond_wait() -> spurious wakeup ->
no avail ring processing ->
virtio_rnd_notify() skips pthread_cond_signal() due to
rnd->in_progress ->
vq_endchains() called needlessly ->
wait in pthread_cond_wait() indefinitely
Fix these uses of pthread_cond_wait() by using predicates.
The only use case without a clear predicate is the tx thread in
virtio-mei, because it works with two-dimensional linked lists.
v1 -> v2:
- fix bugs and comments
- reduce code redundancy
