We were relying on cluster merges not requiring unsafe flagging because
they get merged. If cluster level requests no merging, then we flag
unsafe when merge would have happened.
Before, that was printed using --debug (and in both hb-shape and hb-view).
Changed it, now hb-shape has a new command-line argument called --show-messages.
When invoked, it also respects other output formatting options. The messages
are better formatted and printed to te same place that hb-shape output is
directed to. Previously they were written to stderr.

Add Python scripts to generate the full win32/config.h.win32 and
src/hb-version.h which can be used to build directly from a GIT
checkout. Since the scripts are currently intended for building from a
GIT checkout, these are not distributed in the release tarballs.
Also, support the re-build of Ragel-generated .hh headers using the NMake
build system, and allow one to specify the path of the Ragel executable
if a suitable one cannot be found in the PATH.
Update the Win32/NMake build documentation to let people know about how
these mechanisms can be utilized.
If an application provides a malloc replacement through
hb_malloc_impl() it is important that it is used to allocate
everything, but the use of strdup() circumvents this and
causes system malloc() to be called instead. This pairs
badly with the custom hb_free_impl() being called later.
