This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
The global current_state handle to the current simulator state is a
design idea that was half implemented, but never really cleaned up.
The point was to have a global variable pointing to the state so that
funcs could more quickly & easily access the state anywhere. We've
instead moved in the direction of passing state around everywhere and
don't have any intention of moving back.
I also can't find any references to gdb using this variable, or to
cgen related "dump_regs" functions, both of which were used in the
comments related to this code.
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.
