Make some bpstat functions use bool

Browse Source 
Change return type to bool and adjust function comments.

gdb/ChangeLog:

	* breakpoint.h (bpstat_explains_signal, bpstat_causes_stop,
	bpstat_should_step): Return bool, adjust comments.
	* breakpoint.c (bpstat_explains_signal, bpstat_causes_stop,
	bpstat_should_step): Likewise.
