[PATCH] Remove parameter 'struct breakpoint *t' of encode_actions and encode_actions_1

[Yao Qi <yao@codesourcery.com>]

Hi,
I am going to post a patch series written by Pedro some times
ago.  Some changes are refactor to existing GDB code base, I
extract them from the patch series, and post these preparatory patches
at first.  Here is one:

Functions encode_actions_1 and encode_actions pass both 'bp_location'
and 'breakpoint' in parameters, but the latter can be retrieved from
the former.  The latter one can be removed.  The patch is somewhat
obvious, and review still is welcome.  Regression tested on
x86_64-linux.

gdb:

2013-05-30  Pedro Alves  <pedro@codesourcery.com>
	    Yao Qi  <yao@codesourcery.com>

	* tracepoint.c (encode_actions_1): Remove parameter 't'.
	Caller update.
	(encode_actions): Likewise.
	* remote.c (remote_download_tracepoint): Caller update.
	* tracepoint.h (encode_actions): Update declaration.
