As mentioned in previous patch, wbinvd utilizes the vcpu_make_request
and signal_event call pair to stall other vcpus. Due to the fact that
these two calls are not thread-safe, we need to avoid concurrent call to
this API pair.
This patch adds wbinvd lock to serialize wbinvd emulation.

Commit d575edf79a changes the internal
implementation of wait_event and signal_event to use a counter instead
of a boolean value.
The background was:
ACRN utilizes vcpu_make_request and signal_event pair to shoot down
other vcpus and let them wait for signals. vcpu_make_request eventually
leads to target vcpu calling wait_event.
However vcpu_make_request/signal_event pair was not thread-safe,
and concurrent calls of this pair of API could lead to problems.
One such example is the concurrent wbinvd emulation, where vcpus may
concurrently issue vcpu_make_request/signal_event to synchronize wbinvd
emulation.
d575edf commit uses a counter in internal implementation of
wait_event/signal_event to avoid data races.
However by using a counter, the wait/signal pair now carries semantics of
semaphores instead of events. Semaphores require caller to carefully
plan their calls instead of multiply signaling any number of times to the same
event, which deviates from the original "event" semantics.
This patch changes the API implementation back to boolean-based, and
re-resolve the issue of concurrent wbinvd in next patch.
This also partially reverts commit 10963b04d1,
which was introduced because of the d575edf.

To avoid hardcoding the minimum "iasl" version in multiple places, IASL_MIN_VER
is defined in the top-level Makefile and is passed to config_tools.
This patch verifies "iasl" version against IASL_MIN_VER directly in
config_tools.

At build time (on the *dev* machine), config_tools depends on "iasl" to
generate the binary of ACPI tables for pre-launched VMs.
This patch does:
- pass ASL_COMPILER to config_tools
By default, ASL_COMPILER is initialized by "which iasl" at build time.
User could override it by specifying ASL_COMPILER as the build option,
like below:
make BOARD=xxxx SCENARIO=yyyy ASL_COMPILER=/usr/local/bin/iasl
- use ASL_COMPILER as the path to the "iasl" compiler in config_tools
v1 -> v2:
- add a check to make sure ASL_COMPILER is initialized to a value

At run time (on the *target* machine), acrn-dm depends on "iasl" to build
the ACPI tables for post-launched VMs.
This patch does:
- remove the dependency on ASL_COMPILER, which would only be used at build time
- add a new acrn-dm parameter "--iasl <iasl_compiler_path>"
If "--iasl <iasl_compiler_path>" is specified as the acrn-dm parameter,
acrn-dm uses <iasl_compiler_path> as the path to the "iasl" compiler;
otherwise, "which iasl" is used to detect the "iasl" compiler.
If "iasl" is not found at run time, refuse to launch the post-launched VM
and exit directly.
v2 -> v3:
- use "strlen" rather than "strncmp" to check whether asl_compiler
has been set or not
v1 -> v2:
- remove "iasl_param" and "with_iasl_param" to simplify the logic

Fix the log format problem in devicemodel when using virtio-console with
'stdio' configuration.
In virtio-console, it will change the STDIO's attributes, and will case
the log message after that not align.
e.g:
for (i=0; i<3; i++)
printf('test\n');
The original output would be like this:
test
test
test
After add 'OPOST' to oflag of STDIO, the output would be like this:
test
test
test
(OPOST - Enable implementation-defined output processing)

Following the same logic of commit 59c7077e2 ("config_tools: remove

required since subitems of it either have default values or are optional.

With the default population stage today, the `default` and `minOccurs=0`
attributes are typically mutually exclusive:
* A config item with a `default` attribute is guaranteed to exist after
populating default values, making the `minOccurs` attribute meaningless.
* A config item with a `minOccurs=0` attribute allows that item not to be
present even after default values are populated.
This patch removes the `minOccurs=0` attributes from some config items that have
their default values recently added. This allows the default value populator to
fill in those items as expected if a user does not provide them explicitly.

The debian package created by misc/packaging today is supposed to add an
entry into grub.cfg for the installed hypervisor. Unfortunately, that is
done only when the given scenario XML is named shared, partitioned, hybrid
or hybrid_rt. In the rest of the cases, no entry is added while the default
boot option is still changed to ACRN_deb_multiboot2 which does not exist.
As a short-term workaround, this patch adjusts the branching structure of
the postinst script so that a grub entry is always generated. The entry for
shared scenario is chosen as the default if the scenario XML has a name
other than partitioned, hybrid or hybrid_rt.
This is a workaround only for release 3.0. In future releases we should
migrate to the dpkg-buildpackage using the scripts under debian/.
