Update detect_breakpoint() to better handle single stepping

A stopped thread should sometimes restart, even if a breakpoint
interrupted a single step.  detect_breakpoint() and its interaction with
wait_thread() is updated such that any restart during a single step
scenario properly "requeues" the thread's run intent, by preserving the
doing/donext flags.

Furthermore, detect_breakpoint() ditches its call to get_breakpoint()
and considers any and all breakpoints impacting the current thread PC,
since they may each suggest different restarting requirements.  In
effect, the thread will only remain stopped if at least one relevant
breakpoint allows it to do so.

This reverts commit 5589a9e3afd5 ("Ignore breakpoints during
singlestep").
