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.

Add speed-ups to libunwind.
Add caching of /proc/self/maps data structures.
Add caching of elf image maps attached to the maps data structure.
Add a set of new map api functions to handle creation/destruction of the
maps by external code.
Remove the creation of the maps data structure in the local address space
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.

MIPS coredump support
Add MIPS support to the coredump library. Explicit support for the MIPS
program counter register is added so that we can start backtracing from
the program counter value we read from a core dump. The PC register
support was not strictly required for local backtracing, and we will in
fact just plug the return address to the PC register in getcontext().
I have only tested the 32bit "OABI" paths.

Add initial ARM and MIPS support. To support this, also enable the
reading of .debug_frame sections (used in lieu of .eh_frame sections
when they're not available).
