[patch 1/2] Code reshuffle for patch 2/2 [Re: [patch] Do not bpstat_clear_actions on throw_exception]

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Hi,

just some code moving.  Not sure if bpstat_clear_actions name should stay the
same but why not.


Thanks,
Jan

	No functionality change.
	* breakpoint.c (bpstat_clear_actions): Remove the BS parameter, make
	function comment a reference, new variables tp and bs, move here code
	from throw_exception.
	* breakpoint.h (bpstat_clear_actions): Remove the BS parameter,
	describe it in the comment.
	* exceptions.c (throw_exception): Remove variable tp, move the code for
	bpstat_clear_actions to bpstat_clear_actions.
