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.

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.
