Cyrill Gorcunov 20b7dafaac restore: Add restoration of alternative signal stack 
To restore SAS we have two ways:
- call for sigaltstack explicitly in restorer.c right before we call for sigreturn
- pass stack value to sigreturn call and allow the kernel to restore stack for us

Since second way is a simplier one -- we stick with it.
