last cleanup. Since the oid_arg2 field of struct sysctl_oid is not wide
enough to hold a long, the SYSCTL_LONG() macro has been modified to only
support exporting long variables by pointer instead of by value.

for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

devstat_end_transaction error message that gets printed whenever the
busy count is < 0.
This will help catch drivers that improperly implement devstat(9) support.
- Interface wth the new resource manager.
- Allow for multiple drivers implementing a single devclass.
- Remove ordering dependencies between header files.
- Style cleanup.
- Add DEVICE_SUSPEND and DEVICE_RESUME methods.
- Move to a single-phase interrupt setup scheme.
Kernel builds on the Alpha are brken until Doug gets a chance to incorporate
these changes on that side.

release goes out the door. We know there's a bug in the devstat
implementation in the wd driver, but bde and msmith haven't been able to
fix it yet.
So, disable the printf to avoid confusing/worrying people.
Suggested by: msmith
help track down bugs in the devstat implementation in various drivers.
(i.e., any situation where the driver does not call the devstat routines
once and only once for each transaction initiation and completion)
Prompted by: msmith
generation was causing unaligned access faults on the Alpha.
I have incremented the devstat version number, since this is an interface
change. You'll need to recompile libdevstat, systat, iostat, vmstat and
rpc.rstatd along with your kernel.
