Improve ctrlc responsiveness in interactive mode

* Move most ctrl-c logic to interactive()

 was only a partial fix. This change catches more corner cases where the ctrlc is registered

Fix for #1291

Implement Smrnmi extension

We don't model any sources of RNMI, so this is mostly vestigial.

I believe the fact that mmu_t::refill_tlb was ignoring debug mode
was benign, but certainly paying attention to debug mode is OK.

fesvr: fix compilation with gcc 13

Fix the relationship between Zce and Zcf

Compiling spike with gcc 13 (for example, included in Fedora 38
prerelease) fails with error:

    In file included from fesvr/syscall.h:6,
                     from fesvr/syscall.cc:4:
    fesvr/device.h:15:30: error: ‘uint64_t’ was not declared in this scope
       15 |   typedef std::function<void(uint64_t)> callback_t;
          |                              ^~~~~~~~

This is due to a gcc header dependency change. See for reference:
https://gcc.gnu.org/gcc-13/porting_to.html#header-dep-changes



This commit explicitly adds the missing <cstdint> header inclusion
to fix this build failure.

Use simif_t for devices

In keeping with the spirit of simif_t.

In keeping with the spirit of simif_t.

So we can soon convert those classes to use simif_t instead of sim_t.

To be explicit about which methods of simif_t and htif_t we implement.

Add +symbol_elf flag to fesvr to support loading in symbols from other elf files

When populated, symbol_elfs are additional elf files that populate the
addr2symbol map in htif
