[PATCH 1/5] Share 'enum target_hw_bp_type' in GDB and GDBserver.

[Yao Qi <yao at codesourcery dot com>]

Hi,
'enum target_hw_bp_type' has been used in both GDB and GDBserver.  It
will be used in MIPS hardware watchpoint support too.  This patch
is to share 'enum target_hw_bp_type' in common/break-common.h.

gdb:

2013-06-29  Yao Qi  <yao@codesourcery.com>

	* breakpoint.h: Include break-common.h.
	(enum target_hw_bp_type): Move to ...
	* common/break-common.h: ... here.  New.

gdb/gdbserver:

2013-06-29  Yao Qi  <yao@codesourcery.com>

	* i386-low.c: Include break-common.h.
	(enum target_hw_bp_type): Remove.
