Update Hungarian notation for buffer sizes.

For string lengths EXCLUDING NUL, I use len, whereas cb and cch are
used for string lengths INCLUDING NUL.

cb = byte count = sizeof(a) = narrow string length
cch = character count = sizeof(a)/sizeof(*a) = string length

cb and cch are equivalent for narrow strings. I prefer cch.
