Fix a long standing todo where we let getopt write directly to stderr
when an invalid option is passed. Use the sim io funcs instead as they
go through the filtered callbacks that gdb wants.
Other than the nice advantage of all sims having to declare one fewer
common function, this also fixes leakage in pretty much every sim.
Many were not freeing any resources, and a few were inconsistent as
to the ones they did. Now we have a single module that takes care of
all the logic for us.
Most of the non-cgen based ones could be deleted outright. The cgen
ones required adding a callback to the arch-specific cleanup func.
The few that still have close callbacks are to manage their internal
state.
We do not convert erc32, m32c, ppc, rl78, or rx as they do not use
the common sim core.
The previous profile change broke these sims that use sim-profile but
not sim-cpu (due to missing model support). Add simple funcs until we
can convert these over properly.
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.
Since sim_do_command for many people simply calls sim_args_command, start
a unified version of it. For people who handle their own options, they
could switch to this by using sim_add_option_table instead.
