sizeof(pointer) fixes

[j-huff]

Fixes issues related to incorrect use of sizeof.

Not exactly sure of the the intended purpose of the line:

privateKey = (privKeyBuf + (sizeof privKeyBuf - 1)) - privateKeyLen;

There's no way this was correct, as it would run off the beginning of the privKeyBuf (sizeof privKeyBuf would evaluate to 4 or 8 depending on the size of pointers).

@plindner Is this repo accepting public pull requests?

@iondev33 - please take a look at John's suggested commits: I believe they are all valid corrections to incorrect uses of sizeof (i.e. they address the incorrect use of sizeof() on pointers.. rather than the intended memory block the pointers point to).

@j-huff @SkyDeBaun Yes, we do intend to accept public pull request but because our codebase is managed in a private repo, I will have to "pull" the publicly submitted branch into our private repo first. Test, merge, test, and then release it through the usual mirror process.

I have not done that entire process once yet (it used to be done by Ohio U) but I will. I am adding this to top of my to-do list.
