i'm waiting till dec 7 since that's the deadline you previously gave.

I added argv and envp support, and partial auxv support.
I also added checking for invalid memory accesses when in emulating-mmap mode,
turns out the initial program state is missing something so glibc does a null
dereference, but I never knew until I tried to run the same program from
approximately the same state in gdb in a ppc64le VM. I just copied the stack
pointer and argv/envp/auxv state to gdb, so this means it probably isn't
relocations causing the issue (since those were applied when running in gdb),
I'm guessing a missing auxv entry somewhere.
