Create a class which encapsulates some basic information about an ELF
file and provides a convenient interface for basic reverse engineering.
In particular, ELF automatically loads the symbol table of the given elf
file and recursively creates ELF objects for any linked libraries.

Consolidate some of the r2 calls that get combined to create the symbol
list. Instead of doing multiple calls with different greps within
radare2, just do a single call and search it in the python side. This
gives us a slight, but noticeable performance increase.

forgot to remove the r2 namespace from the calls from back when it was
implemented differently

rev.r2's get_locals() function returns a Symtbl of offsets representing
the local variables on in a stack frame of a particular function. The
offsets returned by r2 are based around the base of the stack, but they
are increasing in value as they grow from the stack. To properly model
memory, they should decrease in value as they grow from the stack.

Add an r2 module with several helper functions that do a number of
simple reverse engineering tasks to aid in writing simple sploit
scripts. The functions in this module invoke radare2 to accomplish their
tasks.

add helper function to invoke ldd to get a list of libraries that will
be linked to a given ELF
