Since we've exposed Lock::from_raw() and Guard::new() publically, we
want to be able to make sure that we assert that a lock is actually held
when constructing a Guard for it to handle instances of unsafe
Guard::new() calls outside of our lock module.
Hence add a new method assert_is_held() to Backend, which uses lockdep
to check whether or not a lock has been acquired. When lockdep is
disabled, this has no overhead.
[Boqun: Resolve the conflicts with exposing Guard::new(), reword the
commit log a bit and format "unsafe { <statement>; }" into "unsafe {
<statement> }" for the consistency. ]
