Make error recovery actually work, i.e. don't hang on SCSI bus resets
...
and re-synchronize before re-scheduling pending operations.
Things seem to be a fair bit stabler now.

Move DMA chip draining to dmaintr() and drain when a (possibly partial)
...
transfer ends in stead of doing it before starting a new transfer.
Use a different CSR bit to wait for "chip not busy" (may be necessary to
make this conditional on chip revision).

Various:
...
- make esp_poll() approximate the given timeout value.
- introduce esp_abort(), and use it for timed out commands; make targets and driver less confused.
- make {free,ready,nexus}-list management somewhat more coherent.
- make sure we only proceed down the state machine in espintr()
if there really is an interrupt pending.

minor cleanups:
...
- don't let pcyl go unassigned if we have a non-sunos disklabel.
if nothing else, guess pcyl = ncyl + acyl.
- don't use bogus disklabel data if disk label is invalid
(xdgetdisklabel() now returns if label was ok or not).
- move xddriver decl. before start of actual code (cleanup).
