5b81af7179 Fix this for non-module (which, i guess, is only i386/ALL). 
XXX: autoconfusion vs. modules is an intolerable mess of stepping
on each others' toes.

c52cab8857 KNF police, remove unnecessary whitespaces and tabulators. Refactor dmioctl 
to not use prop_dictionary_copy* functions if NetBSD_DM_IOCTL command was
not called on device. If disk_ioctl returms anything else then ENOTTY exit
from dmioctl.

b9ba4842ce Hook device-mapper to autoconf framework. Add dm_attach, dm_match and dm_detach 
routines used by autoconf users. Change dm_dev_remove_ioctl to call dm_detach.

This should be primary used by kernel to disable devices during shutdown of
system with nested disk devices.

8f50b1a274 Fix bug in dm_table_resume_ioctl where dmv->flags was sent back to libdevmapper 
except flags variable. This fixes weird behaviour, when worng links to
devices in /dev/mapper were created after lvrename/lvresize.

f26bfe28da Revert my commit which have added knowledge about dm targets to libdevmapper, 
this breaks abstraction. Because only lvmtools/lvmlib and device-mapper can
have knowledge about target mapping and libdevmapper only passes requests
from lvmtools to kernel and back. Bump major library and driver version.

76a0c0e7d2 Fix bug in kmem_alloc/kmem_free of params string. Params string was 
allocated with length DM_MAX_PARAMS_SIZE and released with strlen + 1 size.

Disable KM_NOSLEEP allocation because we do not need them here there is
nothing critical in ioctl part of dm driver.

f6c1b3e09a Some fixes for dm(4). 
- Limit accesses to the size of the volume.
   This fixes a KASSERT in physio_biodone().
 - Change dm_table_size() to return the size of the volume in
   DEV_BSIZE units.  It was reporting it in DEV_BSIZE^2 units.
 - Remove a bit of trailing whitespace.

f5b48500f1 Add support for DIOCGDISKINFO to disk like device drivers. Change 
partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.

No objections on tech-userlevel@.

62e994ce96 Parse dm param string in libdevmapper and not in a dm target init function. 
Create proplib param dictionary entry in libdevmapper and pass it to dm in
dm_ioctl dict.
Param target is then passed to target init function, where is parse. I like
this aproach much better than passing char **argv and trusting to user input.

I have bumped minor lib/driver version.

XXX. Add more sanity checks in kernel.

44e4eeea57 Disable unloading of dm driver when there are any devices defined. This means 
that we have to run lvm vgchange -a n before modunload in NetBSD.

We really need to disable module unloading only for mounted devices, I have
to look at vfs_hooks for mount/umount calls and find way how to mark devices
as mounted in dm driver.
