package/kvm-unit-tests: new package

Browse Source 
The unit tests are tiny guest operating systems that generally execute
only tens of lines of C and assembler test code in order to obtain its
PASS/FAIL result. Unit tests provide KVM and virt hardware functional
testing by targeting the features through minimal implementations of
their use per the hardware specification. The simplicity of unit tests
make them easy to verify they are correct, easy to maintain, and easy
to use in timing measurements. Unit tests are also often used for
quick and dirty bug reproducers. The reproducers may then be kept as
regression tests. It's strongly encouraged that patches implementing
new KVM features are submitted with accompanying unit tests.

[Thomas:
 - order architecture dependencies in Config.in alphabetically.
 - rewrap Config.in help text, lines were too long
 - add an empty line between the package description and the upstream
   project URL in the Config.in help text
 - don't make KVM_UNIT_TESTS_ARCH default to $(ARCH). This was not
   correct for i386 for example. Instead, just handle the few
   architectures that the package supports.
 - remove useless double quotes in variable definitions.
 - remove --prefix="$(TARGET_DIR)" from CONF_OPTS. It was installing
   everything in /share/ and not /usr/share/, and setting the prefix to
   TARGET_DIR at configure time is not good. Instead, pass DESTDIR at
   installation time.]

kvm-unit-tests is a project as old as KVM. As its name
suggests, it's purpose is to provide unit tests for KVM. The
unit tests are tiny guest operating systems that generally
execute only tens of lines of C and assembler test code in
order to obtain its PASS/FAIL result. Unit tests provide KVM
and virt hardware functional testing by targeting the
features through minimal implementations of their use per
the hardware specification. The simplicity of unit tests
make them easy to verify they are correct, easy to maintain,
and easy to use in timing measurements. Unit tests are also
often used for quick and dirty bug reproducers. The
reproducers may then be kept as regression tests. It's
strongly encouraged that patches implementing new KVM
features are submitted with accompanying unit tests.
