Ryan Houdek 0538574dd0 Dispatcher: Supports user provided signal restorer ...

This is required for backtrace to work correctly.
If we are using our custom instruction for returning from a signal, then
backtrace tries to read PC for the sigreturn code and finds our code,
breaking it.

Instead we now /correctly/ support using rt_sigreturn/sigreturn and the
restorer provided from the user.
To facilitate this, we now store a single 64-bit value on the stack to
return our host stack pointer to the correct location from before the
signal.
With cookie checking in place, we can know if an application betrays our
expectations and tries to pass its own signal frames.
If an application in the future /does/ try to pass its own signal
frames, that's unsafe and we cna deal with it then.
