sync: Cache knowledge of kernel uapi version
Previously all libsync calls would try first the modern/mainline uapi
and if that failed try the legacy uapi, or vice versa. This is
inefficient, and confusing when looking at strace. With this change,
after the first successful syscall, libsync know's what uapi version
the kernel supports, and will only try that version in the future.

sync: implement sync_file_info
Also modifies sync-unit-test to use sync_file_info instead of the
deprecated sync_fence_info, but check that they match in several tests.

sync: refactor sync_fence_info
Split the sync_fence_info implementation into multiple functions. This
clarifies the logic, and allows the parts to be reused in the upcoming
sync_file_info function.

sync: Use correct type in size calculation
The previous and current types are the same size, so this wouldn't
have caused a bug in practice, but it is confusing, and would have
been a problem in the unlikely event we changed the size of one of the
types.

Update for kernel headers v4.7.2.
The new uapi kernel headers added a new SEGV reason code, so
add it to the tombstone code.
Update sync.c to include the needed data structures itself. Someone
else will be fixing this to work on old versus new kernels.

libsync: remove linux includes from sync/sync.h
This change removes the #includes of "linux/*.h" headers from the libsync
header. It currently does this by copying the needed structs that are in the
linux headers. This is intended to be a temporary solution.
