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.

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.

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

[ARM] Add support for systems that don't support ucontext.h
Define unw_tdep_context rather than using ucontext_t in order to support
systems that lack ucontext.h. Note that POSIX.1-2008 removed getcontext,
makecontext and swapcontext from its specification.

Remove the appname string of the ARM extbl parser.
There is no need for libunwind to set/fake a name of the elf file from which
the program header came from.

Have the ARM extbtl-parser operate on the DWARF model directly.
This eliminates the arm_stackframe and therefore the need to synchronize the
two models. It also clears the way for unwinding call stacks with mixed
DWARF- and extbl-frames.

Use ARM-specific unwinding tables in unw_step

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.

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).
