Public interface for aborting due to event

[exodist]

$ctx->plan(0, 'skip_all') and $ctx->bail() both send events that basically abort testing. This would normally be a problem because the context would notice it is not released and complain. To get around this both methods do ${$ctx->{_aborted}}++ to tell the context to chill out.

We need a public interface for this for people who write their own abort-now style events.

@haarg needs this.

I am thinking the interface should be $ctx->send_abort_event(...) that is identical to send_event(), but bumps the _aborted ref. I do not think _aborted itself should be publicly exposed.

[haarg]

Would it be possible to use the result of the terminate method on the event? It seems like it should already provide the distinction between abort events and others.

that would be a good idea. +1
