Creating VM images is always a pain to users, and it is especially the case
for those who want to set up the ACRN sample application which needs two
different VM images, one with graphical desktop and the other optimized for
real-time.
This patch introduces the so-called "image builder" utility which is a set
of scripts that can automate the creation of those VM images. The scripts
will take care of:
- Forking image files based on Ubuntu cloud images and enlarge the root
file system per needs.
- Setting up users and passwords.
- Installing necessary packages to run either the graphical desktop or
real-time applications.
- Specific to the RT VM image, disabling services and tweaking kernel
command line for optimized real-time performance.
- Copying the sample applications into the images so that users can
start them directly, after they launch the VMs.

On some platforms the L3 CAT capabilities are not reported via CPUID even
though they are present. The public real-time tuning guide suggests to try
accessing the MSRs directly to detect if L3 CAT is available or not.
This patch implements such guessing logic in the board inspector in order
to enable CAT for users with those kinds of platforms.

The MSR reading and writing routines today has the following issues:
1. The missing of /dev/cpu/*/msr is not properly captured as it is
reported via FileNotFoundError rather than IOError.
2. The wrmsr logic is not updated to use the tmpdevfs msr file.
This patch fixes the issues above which is a prerequisite of adding
additional MSR parsing classes.

In v3.0 the msrfield class has its initializer changed in a way that is
incompatible with the parameter names or the getter/setter. When introduced
from the BITS project, that class allows specifying an MSR field of
arbitrary length by being given the index of the most and least significant
bits.
This patch restores the original behavior of that msrfield class and moves
the use-case specific methods, namely is_vmx_cap_supported and
is_ctrl_setting_allowed, to a helper class.
Parsing of the VMX capability reporting MSRs in msr.py are updated
accordingly, and brief documentation of the MSR fields are added as well.

As the last step to simplify the steps to enable software SRAM passthrough
to a pre-launched RT VM, this patch generates a virtual RTCT which only
contains a compatibility entry (to indicate that the format of the RTCT is
v2) and a couple of SSRAM or SSRAM waymask entries to report the software
SRAM blocks that pre-launched VM has access. That follows the practice how
ACRN device model generates virtual RTCT for post-launched VMs today.
In case RTCT v1 is used physically, this patch still generates a v2 RTCT
for the pre-launched VM but does not add an SSRAM waymask entry there
due to lack of information.

While functionally correct, the ACPI table (mostly DSDT) generation logic
in asl_gen.py contains multiple occurrences that share the same code
structure as follows:
cls = <class of the table>
length = ctypes.sizeof(cls)
data = bytearray(length)
res = cls.from_buffer(data)
<setting multiple fields in res>
To minimize code duplication, this patch refactors the logic by abstracting
the creation of an ACPI table into a method which returns a newly created
object of the given class after setting the specified fields.

Today users still need to manually copy the RTCT binary file when they want
to passthrough software SRAM to a pre-launched RTVM, which is far from
being user friendly.
To get rid of that step, this patch extracts all information from the RTCT
table and format them in the board XML which is the only file users need to
copy from their target platform to build the hypervisor. The patch that
immediately follows will then use such information to generate vRTCT for
the pre-launched VM.
A side effect of this change is that more ranges, which represents those
reported by RTCT such as the CRL binary or the error log area, will be
added to the `memory` section of the board XML. The `id` attributes of
those range will be used to identify what that range is for. As a result,
getting RAM of the physical platform from the board XML requires additional
conditions on the `id` attributes to avoid counting non-RAM regions
unintendedly.

This patch refactors and fixes the following in the ACPI RTCT parser of the
board inspector.
1. Refactor to expose the RTCTSubtableSoftwareSRAM_v2 class directly as
it is a fixed-size entry. There is no need to create a dynamic class
which is mostly for variable-length entries.
2. Rename the "format" field in RTCT entry header to "format_or_version",
as that field actually means "version" in RTCT v2.
3. Properly parse the RTCT compatibility entry which is currently parsed
as an unknown entry with raw data.

BVT schedule rule:
When a new thread is wakeup and added to runqueue, it will get the
smallest avt (svt) from runqueue to initiate its avt. If the svt is
smaller than it's avt, it will keep the original avt. With the svt, it
can prevent a thread from claiming an excessive share of CPU after
sleepting for a long time.
For the reboot issue, when the VM is reboot, it means a new vcpu thread
is wakeup, but at this time, the Service VM's vcpu thread is blocked,
and removed from the runqueue, and the runqueue is empty, so the svt is
0. The new vcpu thread will get avt=0. avt=0 means very high priority,
and can run for a very long time until it catch up with other thread's
avt in runqueue.
At this time, when Service VM's vcpu thread wakeup, it will check the
svt, but the svt is very small, so will not update it's avt according to
the rule, thus has a very low priority and cannot be scheduled.
To fix it, update svt in pick_next handler to make sure svt is align
with the avt of the first obj in runqueue.
