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.

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.

Invert the flag that signals that tdep_init() was called, to move the
symbol from data to BSS.

a9dce3c06e6ffcb83957e734d960505415118f00 25-Apr-2010 Lassi Tuura <lat@cern.ch> During the stack unwinding process, the return address points to
the instruction after the call for a normal frame. libunwind uses
IP-1 to lookup unwind information. However, this is not necessary for
interrupted frames such as signal frames (or interrupt frames) in
the kernel context.

This patch handles both cases correctly.

Based on work by Mark Wielaard <mwielaard@redhat.com>
