Hey Evan

So http://crrev.com/119150 added StringToUint(64), but what I really wanted was
StringToSizeT, and turns out (duh) that size_t is different on each platform; so
I actually need to write it.

I've actually tested the patch (http://codereview.chromium.org/9284013) with
this on more than just Linux, and it works.

Do you think I should remove the Uint conversions since they're not used
anymore?

Yeah, pre-LGTM on adding these and removing the other ones

Defeated!

r119525 started using it :(

Oh man, this is the hardest to submit trivial patch :(
