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.

ccab2054e9 stop parsing breakpoint command if invalid keyword found
With an Ada program, trying to break on a specific Ada task, but
with the wrong capitalization of the `task' keyword, we currently
get only pieces of the "garbage" that caused the error:

    (gdb) b *rendez_vous'address TASK 2
    Garbage 2 at end of command

Pushing this a little further:

    (gdb) b *rendez_vous'address TASK Task TaSK 2
    Garbage 2 at end of command

Another interesting failure mode:

    (gdb) b *rendez_vous'address TASK if
    Argument required (expression to compute).

The parser skipped `TASK', then found the `if' keyword, and thus
started looking for a condition.

This patch fixes the problem by aborting the parsing as soon as
an invalid keyword is found.  This makes it consistent with the
case where the REST parameter is passed as NULL (where an error
is raised immediately after seeing the first invalid keyword).

It also introduces a new testcase that reproduces all above scenarios.

gdb/ChangeLog:

        * breakpoint.c (find_condition_and_thread): Stop parsing
        as soon as the first invalid keyword is found.

gdb/testsuite/ChangeLog:

        * gdb.ada/bad-task-bp-keyword: New testcase.
