Currently, DM only access /sys/kernel/mm/hugepages/hugepages-2048kB/
entries according to its own huge page requirement. So it could have
following race issue:
DM1 DM2
read nr pages
read nr pages
write DM2 nr pages
write DM1 nr pages
Suppose we should write DM1 + DM2 nr page to kernel sysfs interface
to reserve enough huge page (DM1 + DM2). But actually only reserve
huge page requested by DM1. Which could trigger one VM can't boot.
We can easily hit this issue if we enable multiple UOS auto boot
because more than one VM are started at almost same time.
We add file lock to make sure huge page reserving in DM atomic.

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 Event Interrupt (BEI) bit in the TRB descriptor could
delay the triggering of interrupt. For most OSes, the native
driver for xHCI will use this bit to optimize the IO performence,
due to reduction of number of interrupts.
But in Linux, the native xHCI driver for Intel brand controller
doesn't use this bit. It is fine for the native scenario due to
most work is completed by hardware. But in virtualization scenario,
it is almost impossible to support heavy data IO such as high
resolution video recording (ISOC transfer).
Hence, this issue is solved by a 'quirk' when the intel hardware is
emulated (when vendor id is set as 0x8086). For other cases, a
virtal hardware called 'ACRN xHCI' is emulated, and both Linux and
Windows will use BEI bit by default.

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.

Instead, vcpu_affinity is a must for each VM.
This patch also add some sanitize check of vcpu_affinity[]. Here are
some rules:
1) only one bit can be set for each vcpu_affinity of vcpu.
2) two vcpus in same VM cannot be set with same vcpu_affinity.
3) vcpu_affinity cannot be set to the pcpu which used by pre-launched VM.
