acpi unit-test: compare DSDT and SSDT tables against expected values

This test will run only if iasl is installed on the host machine.
The test plan:
1. Dumps the ACPI tables as AML on the disk.
2. Runs iasl to disassembly the tables into ASL files.
3. Runs iasl to disassembly the offline AML files into ASL files....

acpi unit-test: extract iasl executable from configuration

The test checked if iasl is installed by running "iasl"
and checking the error output.
It is better to use the iasl executable as appears
in configuration.

tests: fix acpi to work on bigendian host

Double endianness convertion make this test failing on POWERPC machine
running in big-endian.

This fixes the test to success on big-endian host.

acpi unit-test: renamed ssdt_tables to tables

Just a refactoring, ssdt_tables name was confusing as
it included other tables as well.

acpi unit-test: resolved iasl crash

It seems that iasl has an issue when disassembles
some ACPI tables using the command line:
iasl -e DSDT -e SSDT -d HPET

Modified the iasl command line to "iasl -d HPET"
until the problem is solved. The command line
remained the same for DSDT and SSDT tables....

acpi unit-test: do not fail on asl mismatch

The asl comparison will break every time the ACPI
tables are updated. This may break the git bisect.
Instead of failing print a warning on stderr
including the retained asl files, so they can be
compared offline....

acpi unit-test: adjust the test data structure for better handling

Ensure more then one instance of test_data may exist
at a given time. It will help to compare different
acpi table versions.

acpi unit-test: load and check facs table

FACS table does not have a checksum, so we can
check at least the signature (existence).

acpi unit-test: verify signature and checksum

Read all ACPI tables from guest - will be useful for further unit tests.

Follow pointers between ACPI tables checking signature and format for
correctness. Verify checksum for all tables.

acpi-test: basic acpi unit-test

We run bios, and boot a minimal boot sector that immediately halts.
Then poke at memory to find ACPI tables.

This only checks that RSDP is there.
More will be added later.
