* added breakpoints and stepping * add link register to allow single-stepping a ret instruction, fix stacktraces * refactor to avoid passing the IO layer structs to the breakpoint function * add tests, refine the stacktrace to not include non-function * add register information for core file parsing * core file generation for RISC-V * make tests run under riscv-64 * make tests run under riscv-32
