165557e269 With rotating kernel dumps the higest dump number is not necessarily the
last one. To make it easier to find the last one create symlinks with 'last'
suffix that will point to the files of the last coredump, eg.:

	info.last -> info.5
	textdump.tar.last.gz -> textdump.tar.5.gz

349d039bdb - When checking if a dump exists on the given device there is no need to
provide dump directory. Eliminate this redundant argument. This changes
  the usage, but the only risk here is that a warning will be printed
  about directory given as device.

- Update usage of -C option.

- When clearing dump header from the given device there is also no need to
  provide dump directory, although additional arguments for -c were not
  documented.

- Document that -v can be used with -c and that list of devices can be given.

0c04d1850f Fix an old bug in devd, where it uses std::sort() to sort the various
lists it reads from its configuration files on the priority field.

Because some items in the lists have the same priority, and std::sort()
is not stable, the exact order in which the items are enumerated does
not have to correspond to the order they appear in the configuration
files.

Apparently this was never noticed with libstdc++, but with libc++ it
could cause the "uhid" entry from /etc/devd/usb.conf to be used instead
of the "ums" entry (which is earlier in the file).  This caused the
problem described in the PR: the USB mouse module was never loaded, and
the other actions (such as starting moused) were not executed.

To fix the problem, make devd use std:stable_sort() instead.

734e78dfcb Disallow attaching preloaded memory disks via ioctl.
- The feature is dangerous because the kernel code didn't check
  validity of the memory address provided from user space.
- It seems that mdconfig(8) never really supported attaching preloaded
  memory disks.
- Preloaded memory disks are automatically attached during md(4)
  initialization. Thus there shouldn't be much use for the feature.

6bbfef9004 Fill sin6_scope_id in sockaddr_in6 before passing it from the kernel to
userland via routing socket or sysctl.  This eliminates the following
KAME-specific sin6_scope_id handling routine from each userland utility:

 sin6.sin6_scope_id = ntohs(*(u_int16_t *)&sin6.sin6_addr.s6_addr[2]);

This behavior can be controlled by net.inet6.ip6.deembed_scopeid.  This is
set to 1 by default (sin6_scope_id will be filled in the kernel).

2db62a6b1f - blk_equals() is too strict. If the journal entry defines more frags
than we're claiming it should still be considered an exact match.  This
   would previously leak frags that had been extended.

   numbers we've seen so far for debugging.

549f62fa42 Fix problem with geom_label(4) not recognizing UFS labels on filesystems
extended using growfs(8).  The problem here is that geom_label checks if
the filesystem size recorded in UFS superblock is equal to the provider
(i.e. device) size.  This check cannot be removed due to backward
compatibility.  On the other hand, in most cases growfs(8) cannot set
fs_size in the superblock to match the provider size, because, differently
from newfs(8), it cannot recompute cylinder group sizes.

To fix this problem, add another superblock field, fs_providersize, used
only for this purpose.  The geom_label(4) will attach if either fs_size
(filesystem created with newfs(8)) or fs_providersize (filesystem expanded
using growfs(8)) matches the device size.
