[python][obv] Make result in testsuite/gdb.python/py-breakpoints.c global

[Phil Muldoon <pmuldoon@redhat.com>]

Pedro Alves noticed and brought to my attention on irc that one of the Python breakpoints test fails locally for him.  When I tested it locally, it worked ok for me.  So we investigated. Subsequently it was found (by Pedro, (thanks!) that the test was bogus.  The test was running to main and setting the watchpoint on 'result'. But 'result' was not initialized in the (main) code at this point.  So if 'result' happened to 0 the test would work (as it did for me); however as the inferior is at the main () line, equally 'result' could be any uninitialized value, and the test would fail. I fixed this by making 'result' global in the testcase. This ensures that 'result' is always at the expected value '0' at main.

I'm checking this in under the obvious rule.

Cheers,

Phil
