These two Soong product_variables were usually controlled by
ENABLE_CPUSETS and ENABLE_SCHEDBOOST in BoardConfig.mk. This change
turns the build time variables into runtime decision by checking if
a special file, "tasks", can be found under the mount points,
/dev/cpuset and /dev/stune, for cpusets and schedboost, respectively.
That special file only exists when the corresponding Linux kernel
configurations, CONFIG_CPUSETS and CONFIG_SCHEDTUNE, are set.
Bug: 34726944
Test: Tested on Sailfish with following configurations
neither cpuset nor schedtune enabled in the kernel
cpuset enabled, but schedtune disabled in the kernel
both cpuset and schedtune enabled in the kernel

Moved headers from include/libcutils and include/liblog to
libcutils/include and liblog/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.
Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.
Also added liblog_vndk_headers that exports a special log/log.h for
VNDK.
Moved headers of libcutils to libcutils_headers. They should be used
by modules for header-only inlines. Added libcutils_headers as
dependency of libcutils.
Added libcutils_vndk_headers that exports a special cutils/log.h
deprecating usage of the file. A later CL will deprecate the one in
libcutils_headers
Test: Add above libs to shared lib of local module

Remove debuggerd in favor of a helper process that gets execed by
crashing processes.

files.[h|cpp] is bound to be abused with junk, replace with
android_get_control_file.[h|cpp]. Plus some sundry cleanup.

Solve one more issue where privilege is required to open a file and
we do not want to grant such to the service. This is the client side
of the picture, init is the server. The file's descriptor was placed
into the environment as "ANDROID_FILE_<path>" where non-alpha and
non-numeric characters in the <path> are replaced with _ and this
function picks the file descriptor up.
Added definition ANDROID_FILE_ENV_PREFIX ("ANDROID_FILE_") and
android_get_control_file() prototype in a new include <cutils/files.h>
android_get_control_file() checks if the resulting file descriptor is
valid, open and matches the name reference, which on purpose will fail
if a symbolic link is in the path rather than using a fully qualified
path. Add gTest unit test for both.
Test: gTest libcutils_test --gtest_filter=FileTest.android_get_control_file
