Change in binutils-gdb[master]: Make tui-winsource not use breakpoint_chain

["Christian Biesinger (Code Review)" <gerrit at gnutoolchain-gerrit dot osci dot io>]

Christian Biesinger has uploaded a new patch set version (#3).

Change URL: https://gnutoolchain-gerrit.osci.io/r/c/binutils-gdb/+/22
......................................................................

Make tui-winsource not use breakpoint_chain

That's an internal variable of breakpoint.c. Insted, use
iterate_over_breakpoints to update the breakpoint list.

gdb/ChangeLog:

2019-10-09  Christian Biesinger  <cbiesinger@google.com>

	* breakpoint.c (breakpoint_chain): Make static.
	* tui/tui-winsource.c: Call iterate_over_breakpoints instead
	of accessing breakpoint_chain.
