mmu_pagein() is only useful on sun4/sun4c. For now, keep a `mmu_pagein4m()'

within `#ifdef DEBUG' for monitoring.
Push user windows to stack in pmap_extract() if we need to switch contexts.

Change attributes of `dma', `espdma' and `ledma' (the attributes on the latter
...
two didn't seem to make much sense anyway..) to allow `esp' devices to be
attached to one of `sbus', `dma' and `espdma'.
Remove the wildcarded `espdma?' and `ledma?' attachments of `esp' and `le'
respectively, in favour of `dma?' and `lebuffer?' (but the latter is not
yet implemented), which seems to better match reality: additional SBus
SCSI/Lance boards call themselves `dma' and `lebuffer'.

Re-arrange code that looks for the esp driver to allow for the fact that
...
any "dma" device (i.e. not just "espdma") can have an OBP child. This is
the case with (at least some) SBus SCSI boards.

Use configuration file flags to disable reselection and/or sync negotiation,
...
on a per target basis (until the driver can sort things out on its own).
Test against "sbus" in stead of "espdma" to find out where in the
configuration tree we are: an esp can be the child of a "dma" on SBus
add-on boards.
