Report::frames_mut allows aliased mutable references

Affected versions of this crate return an iterator from

Report::frames_mut whose &mut Frame items have lifetimes independent

of the iterator, so all yielded references can be held at the same time.

A yielded frame's sources are also yielded by the iterator and reachable

through the parent frame via Frame::sources_mut, allowing safe code to

obtain two live mutable references to the same frame. This is undefined

behavior and can be used to cause a segmentation fault (see reproducer in

the linked issue). Versions 0.1.0 and 0.1.1 are affected through

Frame::source_mut instead of Frame::sources_mut.

The flaw is fixed in 0.8.0 by replacing the iterator with internal

iteration: Report::frames_mut now takes a visitor closure, so mutable

access to a frame is scoped and cannot overlap with access to its

sources.
