This introduces a new relative_filename proc to gdb.exp and changes
some tests to use it. This helps make these tests parallel-safe.

* gdb.base/fullname.exp: Use standard_output_file,
relative_filename.
* gdb.base/hashline1.exp: Use standard_testfile,
standard_output_file, relative_filename, clean_restart.
* gdb.base/hashline2.exp: Use standard_testfile,
standard_output_file.
* gdb.base/hashline3.exp: Use standard_testfile,
standard_output_file, relative_filename.
* lib/gdb.exp (relative_filename): New proc.
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.
