Ronald G. Minnich e32e8c3144 prototypes for dram and smbus functions.
We are experimenting a bit here; we are going to put all protos for
lib/*.c into this file. Experience has shown this will not be a large
or messy set of protos. Plan 9 has used this technique and it works
well, as it avoids 100 files with one prototype per file.
If you can't trust Ken Thompson, who can you trust?
