Refactor: Expose const_cast by removing ByteBuffer::warp(const void*, size_t)

Browse source 
This function did a const_cast internally which made the call side look
"safe". This method is removed completely and call sites are replaced
with ByteBuffer::wrap(const_cast<void*>(data), size) which makes the
behaviour obvious.
