The Windows 10 feeds back quicker than Linux OS when error occured
due to device disconnecting, it will quickly reset the xHCI controller
before the DM starts to emulate disconnect event and it may cause some
unexpected errors such as crash.
This patch will do one more check when error happens, if the error
is induced by device disconnecting, the DM will not report error and
just wait until the disconnect event is reported to the guest. This
change could produce the correct hehavior as we expected.

The block count of the struct usb_xfer is hard coded by the macro
USB_MAX_XFER_BLOCKS (1024), it wastes memory if 1024 blocks are
allocated for low speed transfer such as control transfer or interrupt
transfer. This patch introduces a new method to allocate different
number of blocks according to different endpoint type.

In the process of USB data transfer, there three kinds of data blocks:
a. Non data block, which contains some control information;
b. Partial data block, which contains part of a large data chunk;
c. Full data block, which contains a complete data chunk.
In previous implementation, the differences mentioned above are described
by the usb_block::chained. But the 'chained' is concept in the xHCI area
and should not appear in the USB layer. This patch introduces enum type
usb_block_type to replace the 'chained' field in struct usb_block.

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
