Fix initialization problem.
The local address space map init can be called twice. Make sure it's
only called once.

Do not try to read/write device memory.
Device memory might have certain alignment constraints that the unwind
code violates. Since we shouldn't be reading this memory, treat this
type of memory as not readable and not writable.

Use map cache for finding image names.
This change removes the function find_binary_for_address and replaces it
with a call to check the cached map data instead. This is an error path
that hardly ever gets exercised though.
Also fix a couple of warnings in Gfind_proc_info-lsb.c.

Fix return code for unmappable elf data.
If an elf image cannot be mapped for the local unwind, then uninitialized data
gets passed back. Fix this to actually return an error code.

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.
