virtio_free_rx_buffers uses the wrong slot in the vring to get
the buffer index. It uses desc_next. It should be last_used_idx
which is the slot number for the first valid descriptor.

This patch teaches worer threads to sleep and to be waken up by
kernel if there is activity on file desctiptors assigned to that thread.
It also adds counters to epoll file descriptors and new
debug cli 'show unix file'.

Buffers may be allocated for indirect descriptors by tx thread and
they are freed when tx thread is invoked in the next invocation.
This is to allow the recipient (kernel) to have a chance to process
them. But if the tap interface is deleted, the tx thread may not yet
be called to clean up the indirect descriptors' buffers. In that case,
we need to remove them without waiting for the tx thread to be called.
Failure to do so may cause buffers leak when the tap interface is deleted.
For the RX ring, leakage also exists for vring->buffers when the interface
is removed.
