This series implements the sw_sync test and the lib/sw_sync helper functions for said test.
The sw_sync subtests range from very basic tests of the sw_sync functionality, to stress testing and randomized tests.
Changes since v1:

- Fixed fd value checking
- Fixed fd validity check in sw_sync_fd_close()
- Moved sw_sync related paths to define
- Switched from malloc+memset to calloc in sync_file_info()
- Switched sizeof to dereferenced ptr
tests/sw_sync:
- Moved lib/sw_sync related code to lib/sw_sync commit
- Replaced memset with assignment in loop
Changes since v2:
lib/sw_sync:
- Replaced fd validity check in sw_sync_timeline_create()
- Replace sw_sync_XXX_destroy() functions with close()

Changes since v4:
lib/sw_sync:
- Fixed whitespace in sw_sync_fence_count()

- __sw_sync_fence_count_status -> __sync_fence_count_status
tests/sw_sync:
- Added subtest test_sync_expired_merge
- Added subtest test_timeline_closed
- Added subtest test_timeline_closed_signaled

tests/sw_sync:
- Removed nbr_threads from data_t
- Removed nbr_iterations from data_t
lib/sw_sync:
- Removed undue Google/AOSP attribution
