gdb can now read spike memory.
The endianness is wrong, but I think it might be that gdb doesn't have
it right. Need to investigate what architecture gdb thinks it's
debugging.

Listen on a socket for gdb to connect to.
So far it just listens, and gdb times out because it's not getting any
messages back.
Receive packets and verify their checksum.

htif: catch proper store exception ( #44 )
The sim's debug_mmu will generate a trap_load_access_fault if the load
fails, not a trap_store_access_fault. This doesn't materially affect
exection, but results in a nicer log message.

Some bugfixes for CSR reading and setting FS for fflags updates ( #43 )
* csrrc[i] and csrrs[i] don't write CSRs if rs/zimm == 0
* Dirty fp state when setting new fp exceptions
* Set FS to dirty for all non-zero fflags writes.
