Well, both `_DEBUG` and `DEBUG` appear to be defined by Visual Studio in
debug mode. So we still need to rename them, and I'd rather rename them
here than in the next patch series (that will (re-)add support to build in
Visual Studio), as I want the command-line MSVC build to also define both
constants.

No, for consistency with Visual Studio, I want to keep defining both
`DEBUG` and `_DEBUG`. It's just easier that way, as I won't have to spend
extra cycles to remember that those two ways to build Git are slightly
different, when they shouldn't be.

Thanks,
Dscho
