Fix maps caching for local processes.
It is possible for the map to change while running libunwind. For example,
if lots of threads are doing local unwinds at the same time. Allow the
cached map to regenerate when it detects this case.
Included in this change is a refactor of all of the os code so that it can
also be used to do caching. This is a prelude to being able to attempt to
push the code upstream.
Also, this moves the code back closer to the original upstream code.
Hopefully, this will allow me to upstream all of these changes.

Fix memory corruption bug.
There are two problems, some of the init code needs the map created before
the init function since it does a verify check during init. The second
problem is that the local addr space seems to change for reasons I don't
understand, so it's necessary to init the map list when doing a unw_cursor
init.

SuperH port
Add support for the 32bit SuperH architecture running Linux.
Specifically, support is added for SH4, and support for earlier SH
versions and to the 64bit SH5 are left out. This was tested in qemu with
a little-endian SH4 debian image & GCC 4.7 cross compiler.
