Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
The sim keeps track of which allocations are zero-ed internally (via
zalloc) and then calls a helper "zfree" function rather than "free".
But this "zfree" function simply calls "free" itself. Since I can
see no point in this and it is simply useless overhead, punt it.
The only real change is in hw-alloc.c where we remove the zalloc_p
tracking, and sim-utils.c where zfree is delete. The rest of the
changes are a simple `sed` from "zfree" to "free".

I find it annoying when using --memory-mapfile that I also need to look
up and manually specify the file size to the following --memory-region
option. So make a length of 0 in the following --memory-region trigger
an auto-sizing of the map to the length of the file being mapped.

There are options for listing the current device/hw tree and memory
regions, but no way to find out at run time all the current mappings.
So add a new --map-info option akin to the --memory-info option which
displays all the current mappings.

Add support for mmap-based memory regions.
* sim-memopt.c (mmap_next_fd): New global.
(sim_memory_init): Reinitialize it.
(OPTION_MEMORY_MAPFILE, memory_option_handler): Support new
"--memory-mapfile FILE" option. Check for some errors.
(do_memopt_add): Conditionally do mmap instead of malloc for
backing store of simulated memory. Check for more errors.
(do_simopt_delete, sim_memory_uninstall): Corresponding cleanup.
* sim-memopt.h (munmap_length): New member of _sim_memopt.
* configure.in: Look for mmap/fstat related functions and headers.
* config.in, configure: Regenerated.

* sim-memopt.c (memory_options): Add MEMORY_FILL option.
(memory_option_handler): Implement MEMORY_FILL option. Make
MEMORY_CLEAR an alias for MEMORY_FILL=0.
(parse_ulong_value): New function.
(do_memopt_add): Allocate all buffers. Optionally fill them.
that overlapping regions can be defined.
Allow the layer (level) of a memory region to be specified as part of
an address parameter to memory options.
Update simulators.
