Use zero offset when getting bias from memory.
The code to get the bias was incorrectly using the passed in map offset
when reading it from memory. This doesn't work since the offset is the
offset into the apk. Change to always check for a zero in this case.

Fix the caching of the compressed section.
A previous change fixed a race condtion, but caused a big memory
leak of the compressed section data. In order to fix this, move
the caching of the compressed section at the point that we cache
the elf image data itself.

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.

Fix header inclusion order in `src/elfxx.c'
Make sure that we have included `config.h' before checking HAVE_LZMA.
This makes a difference at least on MIPS, where we include `elfxx.c'
directly. For other platforms this does not make much difference, as we
are already indirectly including `config.h' from other headers.

Search MiniDebugInfo for procedure names
After searching the normal symbol table, look if the binary contains
.gnu_debugdata section. If it does, run LZMA decompression on it, load
the resulting ELF image into memory and call lookup_symbol() on it
again.
lookup_symbol() is modified so that it takes min_dist as a parameter and
only returns a symbol when it finds one that is closer than indicated by
the parameter.

Introduce a tdep_get_func_addr_hook() in the ELF lookup_symbol()
routine and add address-space argument. This is needed because on
PPC64, a the function-name symbol refers to a function descriptor
(unlike, for example, on ia64, where the @fptr() operator is needed to
refer to a function descriptor). Thus, in order to look up the name
of a function, we need to dereference the function descriptor. To
make matters more "interesting", the function descriptors are normally
resolved by the dynamic linker, so we can't get their values from the
ELF file. Instead, we have to read them from the running image, hence
the need for the address-space argument.
