o Document debug level keyword
o Implement debug level:
o For most of the diagnostic messages, change them from #ifdef DEBUG
to if (debuglevel > 0).
o Add a couple more diagnostic messages that weren't present before
o Fix a couple of excessively long lines.

o Start to implement the stopgap kludge for -current's pccard code by passing
the length of the i/o range. If DEV_DESC_HAS_SIZE is defined, we'll set
the size. This is done as an ifdef so that I can generate patches
against the kernel more easily.
o Add preliminary support for tweaking sleep times, but leave it
disabled until a good range of values can be established.
Didn't fix: logmsg problem noted by Nate.
