[PATCH 03/14] libxl: provide TOSTRING in libxl_internal.h and libxlu_internal.h

[Ian Jackson <ian.jackson@eu.citrix.com>]

From: Ian Jackson <ijackson@chiark.greenend.org.uk>

Provide a copy of the standard TOSTRING macro in libxlu_internal.h,
for the benefit of patches later in this series.

Also, move TOSTRING to libxl_internal.h from a .c file for the
benefit of future other callers in libxl proper.

(These cannot be combined because libxlu cannot include
libxl_internal.h and libxl should not include libxlu_internal.h.)
