Fix test_array_unaligned

See comment inline, need to force alignment of the array some how.

Travis not activated

There's a .travis.yml but https://travis-ci.org/nrc/zero doesn't appear to have been activated?

read_str() should return a Result instead of panicking

Wasn't sure whether to file this as an issue in this crate or in your xmas-elf crate, but I chose here because the lowest-level change should be made here.

In the read_str() function, there is the potential to panic on the expect statement. When parsing a file (such as an ELF file using your xmas-elf crate), some symbols may not be encoded as UTF-8, so it'd be nice to be able to skip them and recover gracefully through a returned Result, rather than simply panicking and aborting the entire parse thread.

If you're okay with that change, I'm happy to submit a pull request to both this and the xmas-elf crate.

Also, thanks a lot for this and the xmas-elf crate, and also for making the change for my previous issue with the elf flags. It's really saved me a lot of time!!

`zero` on crates.io seems outdated

https://docs.rs/crate/zero/0.1.2/source/src/lib.rs

It doesn't check the alignment as it is on GitHub:

zero/src/lib.rs

Lines 51 to 59 in 4a72475

 pub fn read_array<T: Pod>(input: &[u8]) -> &[T] { 

 let t_size = mem::size_of::<T>(); 

 assert!(t_size > 0, "Can't read arrays of zero-sized types"); 

 assert!(input.len() % t_size == 0); 

 let addr = input.as_ptr() as usize; 

 assert!(addr & (mem::align_of::<T>() - 1) == 0); 

 unsafe { read_array_unsafe(input) } 

 }

Maybe publish a new version?
