9bbaf71ba2 Refcount ukfs_part. Otherwise it's not possible to call ukfs_mount() 
several times with only one ukfs_part_probe().

262f83ce50 Use range locking (fnctl(F_SETLK)) instead of file locking (flock()). 
This allows to mount multiple (non-overlapping) partitions from the
same disk image.

72e7011c7a Init ukfs__part_{na,none} statically instead of at runtime to avoid 
init-order lossage from p2k/rump_smbfs, as noted by Tron.

0c29df1074 Improve the ukfs magicpath interface a bit: 
* rename PART to DISKLABEL
* allow to take an OFFSET range to make it possible to access an image
  where there is no disklabel present
* make future extensions easier and less intrusive for the callers

ae7625c02d Add what is essentially disklabel support. All disk-based file 
systems should be mounted with ukfs_mount_disk() from now on.  The
partition argument specifies which label is being mounted (or the
entire image).  E.g. partition 4 should be label 'e'.

323d1b6573 * allow callers to store a private data pointer behind the ukfs handle

e99ca06d65 Give rump_sys_unmount() in ukfs_release() a curlwp context. This 
prevents use-after-free and should fix crashy cases reported by
Arnaud Ysmal.

ee47269736 Since rump rootfs now supports creating directories, mount ukfs 
mounts at the requested mountpoint instead of as the rump kernel
rootfs.  While doing so, generally convert everything to use system
calls instead of handcrafter rump interfaces (e.g. rump_sys_mount()
instead of rump_mnt_mount()).  This avoids a lot of unnecessary
fuss.

Change UKFS_DEFAULTMP from / to /ukfs and bump ukfs version.

6e63908b9f Since rump_module_load() doesn't actually load the module, change 
the name to rump_module_init().  Also, adjust the signature to take
a direct pointer to modinfo and allow passing of props.  Finally,
provide rump_module_fini().

45ef580f17 Merge librumpfs_ufs into librumpfs_ffs. This reflects what happened 
with the ffs kernel module and follows the trend of retiring ufs.
It also allows to get rid of a special case kludge in runtime module
loading, since ufs was not really a module.  librumpfs_ufs is now
obsoleted and ffs consumers should be linked solely against
librumpfs_ffs.

d5aab2d6c4 Do not flock() block devices. The kernel recently started to guard 
against opening a block device twice and flock requires that we
keep the device open.  Hence, the same mount would attempt to open
for locking and then VOP_OPEN for kernel access and run into
problems.  This makes it possible to rump_foofs block devices again,
i.e. take the same command line arguments as regular mounts.
Noticed by apb.
