[commit] switch "info copying/warranty" to GPLv3

[Joel Brobecker <brobecker at adacore dot com>]

Thanks to Andreas for sending his patch to copying.awk. I don't know
why it didn't work when I made what looks like the same change (oh well).

I just checked in the following changes:
  1. Update copying.awk to handle the new license text.
  2. Update the testsuite to accept the new copying/warranty output.

        * Makefile.in (copying.c): Use the top-level COPYING3 as the file
        that contains the GDB license.
        * copying.awk: Adjust to the GPLv3 wording.
        * copying.c: Regenerate.

        * gdb.base/default.exp: Adjust the expected output of "info
        warranty" after the switch to GPLv3.

In this case, if you actually look at the patch, you'll find that
I really reduced the amount of text I'm actually matching. I felt
like matching the entire output of the command was unnecessary,
and reducing it makes the regexp quite a bit smaller.

This is a bit non-obvious, but I figured that it'll be easy to fix
this issue if others disagree. And in the meantime, I'm could commit
the change to copying.c without waiting.

Tested on x86-linux, and all checked in.
