This patch converts the first 25% of libata-core.c to the new debugging scheme.

Looks good at first glance, though I'll hold off on apply until I return
from the Red Hat Summit in Nashville.
It made me remember another point, though: in order to avoid
regressions, after applying your patch, I would think that you would
want to create a patch which did something like
#ifndef ATA_VERBOSE_DEBUG
ap->msg_enable = xxx
#else ATA_DEBUG
ap->msg_enable = yyy
#else
ap->msg_enable = ...
#endif
Ok, i was thinking something along the lines of the following; for better
granularity we might add more ATA_XXX defines or let the user subsequently
adjust dbg level through sysfs...? (The patch applies on top of the one i sent you
before.)
Adjust initial debugging levels through preprocessor defines.
