Adds a macro that rounds a given integer up to the nearest DWORD.
The config block data structure needs to be DWORD aligned. Since config blocks
are run-length encoded, the size of all config blocks therefore needs to be in
DWORD increments. This macro aids in storing arbitary data in a config block.
