tools/lib/lockdep: Fix 'unused value' warnings
...
liblockdep defines various macros that may expand to an expression
with no effect, while the in-kernel definition does have an effect.
This results in warnings from gcc when -Wunused-value is enabled, and
is is enabled by -Wall. Fix this by introducing trivial functions,
as function return values are generally allowed to be ignored.

tools/liblockdep: Correct macro for WARN
...
As Peter Zijlstra pointed out, the varargs for WARN() are
optional, so we need to correctly handle the case where they
don't exist.
This would cause a compilation error.

Recent changes to kernel/locking/lockdep.c broke the liblockdep build. Fix
that.

liblockdep: Wrap kernel/locking/lockdep.c to allow usage from userspace
...
kernel/locking/lockdep.c deals with validating locking scenarios for
various architectures supported by the kernel. There isn't
anything kernel specific going on in lockdep, and when we
compare userspace to other architectures that don't have to deal
with irqs such as s390, they become all too similar.
We wrap kernel/locking/lockdep.c and include/linux/lockdep.h with
several headers which allow us to build and use lockdep from
userspace. We don't touch the kernel code itself which means
that any work done on lockdep in the kernel will automatically
benefit userspace lockdep as well!
