can provide the correct context to each signal handler.
Fix broken sigsuspend(): don't use p_oldsigmask as a flag, use SAS_OLDMASK
as we did before the linuxthreads support merge (submitted by bde).
Move ps_sigstk from to p_sigacts to the main proc structure since signal
stack should not be shared among threads.
Move SAS_OLDMASK and SAS_ALTSTACK flags from sigacts::ps_flags to proc::p_flag.
Move PS_NOCLDSTOP and PS_NOCLDWAIT flags from proc::p_flag to procsig::ps_flag.

to be dangerous. It will better serve us as a port building a KLD,
ala SKIP.
The hooks are staying although it would be better to port and use
the NetBSD pfil interface rather than have custom hooks.
their HotRod controller and on SIIG PCI ultra DMA controller. These
changes also made lots of the Promise code go away, its all much more
generic this way.
Get rid of atapi_immed_cmd, instead use the queue to move atapi commands
from interrupt context if nessesary, the entire atapi layer has
gotten an overhaul.
Lots of fixes to utililize the new features in subr_disk.c etc, and
get rid of the last biots of softc arrays in the drivers, the
only one left is atadevices which cannot easily go away (yet).
Use our own malloc names, its a lot easier to track memory usage this way.
General cleanup overall.
- Let physio take read/write compatible args and have it use uio->uio_rw
to determine the direction.
- physread/physwrite are now #defines for physio
- Remove the inversly named minphys(), dev->si_iosize_max takes over.
- Physio() always uses pbufs.
- Fix the check for non page-aligned transfers, now only unaligned
transfers larger than (MAXPHYS - PAGE_SIZE) get fragmented (only
interesting for tapes using max blocksize).
- General wash-and-clean of code.

NOTE: This will break building ntpd until ntpd has been upgraded to also
support draft 05. People that want to build ntpd in the meantime can
get patches from me.
- Work around a problem not yet solved in the tree (but solved in mine.)
device_get_ivars() should never be cast to a struct resource_list *
The solution, under review, involves the creation of a
device_get_resource_list() function. More later.
