Subject: [PATCH 12/24] perf unwind: Decouple thread->address_space on libunwind

From: He Kuang <hekuang@...wei.com>

Currently, the type of thread->addr_space is unw_addr_space_t, which is
a pointer defined in libunwind headers. For local libunwind, we can
simple include "libunwind.h", but for remote libunwind, the header file
is depends on the target libunwind platform. This patch uses 'void *'
instead to decouple the dependence on libunwind.
