Build and run gpio when output directory is the src dir.  gpio has
dependency on tools/gpio and builds tools/gpio objects in the src
directory in all cases making the src repo dirty even when object
relocation is specified.

This fixes the following commands from generating gpio objects in
the source repository:

make O=dir kselftest
export KBUILD_OUTPUT=dir; make kselftest
make O=dir -C tools/testing/selftests
expoert KBUILD_OUTPUT=dir; make -C tools/testing/selftests

The following commands still build gpio objects in the source repo
(gpio Makefile needs to fixed):
make O=dir kselftest TARGETS="gpio"
export KBUILD_OUTPUT=dir; make kselftest TARGETS="gpio"
make O=dir -C tools/testing/selftests TARGETS="gpio"
expoert KBUILD_OUTPUT=dir; make -C tools/testing/selftests TARGETS="gpio"

Test files created by test_create() and test_create_empty() tests will
stay in the $efivarfs_mount directory until the system was rebooted.

When the tester tries to run this efivarfs test again on the same
system, the immutable characteristics in that directory will cause some
"Operation not permitted" noises, and a false-positve test result as the
file was created in previous run.

"make kselftest" fails with "Circular Makefile.o <- prepare dependency

Make level 0: Main make calls selftests run_tests target

Make level n: selftests lib.mk invokes main make's headers_install

The secondary level make inherits builtin-rules which will use the rule
to generate Makefile.o  and runs into "Circular Makefile.o <- prepare

Invoke headers_install target with --no-builtin-rules to avoid circular

In addition, lib.mk installs headers in the default HDR_PATH, even when

The get_secureboot_mode() function unnecessarily requires both
CONFIG_EFIVAR_FS and CONFIG_EFI_VARS to be enabled to determine if the
system is booted in secure boot mode.  On some systems the old EFI
variable support is not enabled or, possibly, even implemented.

This patch first checks the efivars filesystem for the SecureBoot and
SetupMode flags, but falls back to using the old EFI variable support.

The "secure_boot_file" and "setup_mode_file" couldn't be quoted due to
globbing.  This patch also removes the globbing.

since it seems the glibc() abort handler makes a call to getpid(),

makes sure ASSERTs execute to stop from spawning the listener.

kselftest runs as a userspace process.  Sometimes we need to test things
from kernel space.  One way of doing this is by creating a test module.
Currently doing so requires developers to write a bunch of boiler plate
in the module if kselftest is to be used to run the tests.  This means
we currently have a load of duplicate code to achieve these ends.  If we
have a uniform method for implementing test modules then we can reduce
code duplication, ensure uniformity in the test framework, ease code
maintenance, and reduce the work required to create tests.  This all
helps to encourage developers to write and run tests.

Add a C header file that can be included in test modules.  This provides
a single point for common test functions/macros.  Implement a few macros
that make up the start of the test framework.

Add documentation for new kselftest header to kselftest documentation.

Currently if we wish to use kselftest to run tests within a kernel
module we write a small script to load/unload and do error reporting.
There are a bunch of these under tools/testing/selftests/lib/ that are
all identical except for the test name.  We can reduce code duplication
and improve maintainability if we have one version of this.  However
kselftest requires an executable for each test.  We can move all the
script logic to a central script then have each individual test script
call the main script.

Oneliner to call kselftest_module.sh courtesy of Kees, thanks!

Add test runner creation script.  Convert
tools/testing/selftests/lib/*.sh to use new test creation script.
