Make sure that elf_image structure is copied.
A previous change modified the code so that a pointer to the elf_image
structure from the map data was returned instead of copied. This can
cause a race condition when doing local unwinds if the map needs to be
rebuilt. One thread might have a pointer to a freed data structure.
To fix this, make sure that the elf_image is always copied when the
contents are going to be used.
In addition, remove the map pointer in the mapped data because it could
also be stale when a local unwind causes a map rebuild. Add a big comment
in front of the elf_image structure to explain this so it won't happen
again.

Update all mapoff checks to check against 0.
The dlopen of a shared library from an apk results in huge non-zero
map offsets. This can cause failures due to the checks in the code
of the map offset against the elf data.
We don't really support a non-zero offset for an executable map,
so it's easier to assume this is always zero.

Implement method to read elf data from memory.
I rewrote the entirety of elfxx.h/elfxx.c to support this.
For the rewrite, I modified the way that the symbol tables are searched.
The searched every single entry in the symbol table, and all symbol tables.
The new method finds the first entry that actually has a name and stops.
I also added some quick checks to make sure that a malformed elf would
not cause a crash when reading the symbol names from the symbol tables.
I had to implement the functionality of dwarf_find_unwind_table to handle
reading from memory, instead of from a file. I didn't implement debug frame
support since that likelihood of that appearing in memory seems low.
I also modified the dwarf_find_unwind_table to remove an abort and just
fail if that particular path is encountered. In addition, I added a quick
check to make sure that a malformed dynamic section doesn't cause a crash.

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 a new option to conserve stack space.
There are a few places where large data structures are put on the stack.
This causes failures when trying to dump threads using a smaller stack so
use an option to conserve stack space.
Tested by running these commands:
autoreconf -i
./configure
Verify that config.h has CONSERVE_STACK undefined since this is a host build.
autoreconf -i
android/conf_arm.sh
Verify that config.h has CONSERVE_STACK defined.
Built libunwind with both CONSERVE_STACK define and undefined.

Prevent the use of struct dl_phdr_info outside of dl_iterate_phdr
Since the dl_iterate_phdr is required for local unwinding only the use of
struct dl_phdr_info can be eliminated in case libunwind gets compiled for
remote unwinding. This enhances libunwinds portability to targets that
don't provide any dl_iterate_phdr functionality.

Change _UPTi_find_unwind_table to return an integer.
This keeps the definition on IA64 and all the other architectures in sync with
the declaration of _UPTi_find_unwind_table. This also mimics the behaviour of
what's done for local unwinding and allows the function to provide more than
one way to undwind.
