[drlvm][port][signals] VM does not show assertion dialog on failed asserts

                 Key: HARMONY-5656
                 URL: https://issues.apache.org/jira/browse/HARMONY-5656
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Windows
            Reporter: Ilya Berezhniuk

When an assertion fired, VM does not show assertion dialog on Windows regardless of "vm.assert_dialog"
The only case when assertion is displayed in a dialog is when crash handler is not initialized

The problem appears because in current crash handler design all CRT events are set up in crash
handler initialization to print comsole message and do not display a dialog.
The sceme supposed to re-enable CRT event setting in VEH. The problem with assert() is that
the signal is caught neither in VEH nor in CRT handler.

I can see 2 approaches to fix the problem:
1) Change CRT settings immediately when crash handler output flags are changed. This method
introduces additional platform dependency and thus does not look good for me, but it shoul
work stably.
2) SIGABRT handler can be registered on Windows, but Unix-like signals handling looks ugly
in Windows environment.

I'm going to try both methods, and provide a patch for working one.
