[PATCH 0/6] Fix a bunch of run control bugs.

I started out by doing a couple tweaks to
signal-while-stepping-over-bp-other-thread.exp, to make it run against
remote targets too, and then that didn't work, because of some bug.
And then fixing that bug required fixing some other bug, and ...
Well, this is the result. This changes heavily core run control code,
which affects software single-step targets too. For more comfortable
development and testing, I actually hacked on this against my software
single-step on x86 branch first.

Fix missing breakpoing/watchpoint hits, eliminate deferred_step_ptid.
Fix for even more missed events; eliminate thread-hop code.
Handle multiple step-overs.
Make signal-while-stepping-over-bp-other-thread.exp run against
remote targets too.
