remove system ceiling from lock_mut
closure
...
now it's impossible to do a `borrow` within that critical section as a borrow of
the task priority is required (and that's already mutably borrowed by the
`lock_mut` closure)

remove the borrow_mut method from resources
...
it can be used to break references rules within nested locks
``` rust
static R1: Resource<bool, C1> = unsafe { Resource::new(false) };
static R2: Resource<bool, C2> = unsafe { Resource::new(false) };
static R3: Resource<bool, C3> = unsafe { Resource::new(false) };
// Priority = 1
extern "C" fn j1(task: interrupt::Exti0Irq) {
R1.lock(&task, |r1, c1| {
R2.lock(&task, |r2, c2| {
R3.lock(&task, |r3, mut c3| {
// BAD &- and &mut - that point to the same data
let r1_ref: &bool = R1.borrow(&c2);
let r1_ref_mut: &mut bool = R1.borrow_mut(&mut c3);
});
});
});
}
