Fix aarch64 handling of error code.
In the is_signal_frame call, there is an error return path that can
return a non-zero value. Unfortunately, only zero is considered an
error, so this causes the frame to be handled incorrectly.
Once this was fixed, I also modified the code so that if the treating
the unwind as in a signal frame fails, we can fall back and try a couple
of different paths.
It turns out this is_signal_frame check was broken on arm too.

Correctly identify the aarch64 kernel's signal trampoline.
This was misfiring because it was seeing a "corrected" PC that pointed
to the nop before the mov that's the first instruction in the trampoline.

Fix ip adjust on aarch64.
I didn't add the ip adjust when aarch64 support was added. This meant that
the ip pointed to the wrong instruction when doing unwinds.

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.

AARCH64: Change Debug calls to use %lx instead of %x.
The attached patch simply modifies the Debug statements for aarch64 to use
%lx instead of %x. Tested by compiling for aarch64 using a cross-compiler.

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.

For current process, check memory accesses.
When attempting to unwind the current process, the library simple reads and
writes to memory for memory accesses. Unfortunately, if an unwind winds up
with invalid data, then the process can segfault. Add a guard to all memory
accesses that verifies that reads/writes are valid before attempting them.
For now, this guard is a nop on all systems except linux systems.
Also, modify the adjust_ip function to use the access_mem function
so that all reads go through the right function.
