Warner Losh 673b7bf483 o Add "debuglevel" keyword to config file.
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.
Reviewed by: hosokawa-san

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.
