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.

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.
