Add --dmi-rti and --abstract-rti to test OpenOCD.
Optionally make spike behave more like real hardware, to automatically
test OpenOCD's handling of such hardware.

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.

If I'm reading the ISA manual correctly, the disassembler was just wrong
here.
