Syscalls-logic

Logical definitions for syscalls to be used in the application-level view for reasoning

All the *-logic functions (like syscall-read-logic) should be untouchable (push-untouchable) --- we want to disallow the use of these functions during evaluation as well as proof since they aren't the top-level interface functions (like syscall-read).
