Worth noting that the ByteString Fill and Expand are now removed. So its
just String that retains Fill/Expand.

I handled the ByteString::Fill generally on a case-by-case basis. e.g.
565587eba10a8c4e01d4346669327bd9065c5dfa where the idea was simply to
write 512 0's to disk

Generally IIRC StringBuffers were the way to go. You can find
padToLength in comphelper/inc/string.hxx which expands a buffer to the
desired length and pads it with the requested character, which is pretty
much an equivalent to the "Expand" concept anyway.
