Allow stack frames to hold SwfSlices, which are `Rc` already.
...
Functions that manipulate the stack now run inside of `with_current_reader_mut`, which calls a given function with a Reader for the current stack frame. If the stack frame still exists after that code runs, we update it's PC with the Reader's position.

Give AVM1 the notion of a stack frame.
...
This necessitates the use of a copy of SWF data into the GC arena, along with unsafe (and possibly unsound) pointer manipulation to get the action reader to hold a GC pointer.

avm1: Fix GotoFrame2 one-frame-off error
...
Frame numbers pushed/popped from the stack for GotoFrame2 are
1-based. This differs for GotoFrame which is 0-based and encodes
the frame alongside the instruction.

core: Initial implementation of SetTarget2
...
Implement the SetTarget2 action, which pops the target off of the
stack, and GetProperty 11, which pushes _target.
However, our implementation of _target is not accurate yet,
because it requires dynamically building the target path. Currently
we fake it by caching the last path to tellTarget.

core: Improve TellTarget support
...
The AVM1 contains an explicit "target clip" that is used for older
Flash 4-era actions. This target clip can be set to an invalid
value, at which point Play, Stop, etc. will fail silently.
For GetVariable and SetVariable, if the target is invalid,
the variables will be modified on root ("/").
