Add "--log-cache-miss" option to generate a log of cache miss. ( #241 )
* Add "--log-cache-miss" option to generate a log of cache miss.
- This option must be used with "--ic" and/or "--dc" options
to enable cache simulation.
- This option is useful with "-l" option to understand
which instruction has caused the cache miss.
* Modify log format of cache miss to reduce log size.

Add debug module authentication.
Off by default, enabled with --debug-auth.
The protocol is very simple (definitely not secure) to allow debuggers
to test their authentication feature. To authenticate a debugger must:
1. Read authdata
2. Write to authdata the value that it just read, plus 1

mem_t: Throw an error if zero-sized memory is requested ( #168 )
* mem_t: Throw an error if zero-sized memory is requested
If for some reason the user requests a memory size of 0 megabytes, print
a useful error message.
* Check for overflow in memory size
If the user passes in a large enough memory size (-m) that the size in
bytes doesn't fit into size_t, catch this error in the make_mems function.

Also add an implicit ebreak after the program buffer. This is not part
of the spec, but hopefully it will be.

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.
