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.

USB device is connected before UOS is booted up, this scenario is
called 'cold plug' for easy to refer.
Under 'cold plug' situation, the libusb will not report 'connect'
event to device model, hence UOS will not discover 'cold plugged'
device.
This patch add support to fix this issue.

Flat Mode for hub emulation means DM emulates USB devices under hub but
hide hub itself. Under this design the Guest OS cannot see any emulated
hub. So in the perspective of Guest OS, all the emulated devices are
under root hub.
This patch is used to enable feature as mentioned above. And please NOTE,
it is the initial version of hub flat Mode hub emulation, there are one
limitation: only one physical hub is supported. If second physical hub is
connected, the connect and disconnect behavior in second hub may affect
the function of first emulated hub.
The USB HUB device model should be the final long term solution, but it is
very complex. Use flat mode HUB emulation as the short term solution first
to support some USB touch devices which integrated internal HUB.

This patch implements RTC feature that UOS can set RTC wakeup timer
to IOC firmware with a specific time before enter S3/S5. IOC mediator
also needs to indicate RTC wakeup reason to UOS after exit S3/S5.

In the current implementation sigev_notify is configured as
SIGEV_THREAD. When timer expires an async thread is created and
the registered timer callback is called in the context of this
thread. vrtc_update_timer will access the global data vrtc. There
is a race condition that vrtc is freed when deinit and then a timer
expires. In this case vrtc_update_timer will access a freed buffer
which causes problem such as heap corruption and segment fault.
In this patch signal model is used when timer is created. The signal
is masked and a signalfd is used to poll on it with mevent. This avoids
the race condition.

This patch fixes an issue that CBC signal channel
is inactive after SOS resuming, it leads to IOC mediator
cannot transfer any signals between UOS and SOS. So IOC
mediator sends the open channel command to activate CBC
signal channel after resuming.

CMOS offset from 0x20 to 0x9F is used to store rpmb key information.
vsbl loader will init vrpmb key in CMOS when boot/reboot.
vsbl loader will not init vrpmb key during S3 resume.
vsbl will read vrpmb key via CMOS interface.
After reading, the key value is cleared in CMOS. So the key can only be
read once until next boot.
