Markus Metzger 9accd112a6 Add the gdb remote target operations for branch tracing. 
We define the following packets:

  Qbtrace:bts         enable branch tracing for the current thread
                      returns "OK" or "Enn"

  Qbtrace:off         disable branch tracing for the current thread
                      returns "OK" or "Enn"

  qXfer:btrace:read   read the full branch trace data for the current thread

Joel Brobecker 28e7fd6234 Update years in copyright notice for the GDB files. 
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.
