use size_t instead of unsigned in a bunch of appropriate places

[joshuawarner32]

This would theoretically break compatibility with apps using embedded
classpaths, on big-endian architectures - because of the size type
extension. However, we don't currently support any big-endian
architectures, so it shouldn't be a problem.

Once again, Travis tells us the build is fine when it's not. Boo. Hiss.

Good thing you look at the output; I haven't been. When running ./test/ci.sh locally, it does what we want (fails on errors), so it's either travis's fault, or it's something weird we're doing in our configuration (.travis.yml). @sgoings, could you take a look?

Actually, I'm able to reproduce this with test/ci.sh locally, too. It looks like it might be related to our use of && and || to do conditionals instead of if/then, with the result that when "make mode=debug bootimage=true test" fails, it doesn't error out of the script; it only skips the next item in the && chain.

This seems to fix it:
