[PATCH 2/2] Remove mark_async_signal_handler_wrapper.

[Yao Qi <yao@codesourcery.com>]

Hi,
Back to year 1999~2000, the type of sigFOO_token is PTR, and
mark_async_signal_handler_wrapper is to cast parameter from type PTR
to 'struct async_signal_handler *'.  After 2001, looks we started to
eliminate PTR from source, and the type of sigFOO_toke is changed to
'void *'.  After previous patch, the type is finally changed to
'struct async_signal_handler *', so the cast is not necessary anymore.

This patch removes function 'mark_async_signal_handler_wrapper', and
use 'mark_async_signal_handler' instead.

gdb:

2012-10-21  Yao Qi  <yao@codesourcery.com>

	* event-top.c (mark_async_signal_handler_wrapper): Remove.
	* event-top.h: Remove its declaration.
	(async_request_quit): Call mark_async_signal_handler instead of
	mark_async_signal_handler_wrapper.
	(async_do_nothing, async_disconnect): Likewise.
	(async_stop_sig): Likewise.
	* remote.c (handle_remote_sigint): Likewise.
	(handle_remote_sigint_twice): Likewise.
