Re-use the existing memory core that handles reads/writes. This drops support for the dumpmem command, but gdb itself has support for dumping memory regions. The verbose command is converted to the common --verbose flag since only two call sites use it now. Support for the clearstats command is dropped entirely, but no other sim really does this, and the same thing can be done by reloading. If it's important (clearing cycle stats) to someone, we can add a common function for it.
