--- 20100914:
Add -D flag to pkg_install, to override the "pkg_add -U" check that
all depending packages have their dependencies satisfied by the new
package.  Essentially, split off this particular behavior as a special
case of -f, so that -f works as before, unforced works as before, and
one can give -D to override exactly this check, leaving all other
checks intact.

The -D flag is in support of make replace, as the workflow for make
replace is that inter-package dependencies are sometimes violated (but
then one must replace the depending packages, which is what
pkg_rolling-replace does via the unsafe_depends flags).

Add missing break statement in option parsing of "pkg_add -C", riding
the version bump.

redo result buffer allocation, to avoid dynamic allocations:
-use exponentially growing buffer sizes instead of just linear extension
-drop the dynamic allocation of buffer metadata introduced in rev.1.8 --
if the initial array is not sufficient something is wrong
-apply some (arbitrary, heuristic) limit so that compressed data
which extract into insane amounts of constant data don't kill the system
This addresses PR kern/36864 by Wolfgang Stukenbrock. Some tuning
might be useful, but hopefully this is an improvement already.

Add a new inode flag, SF_SNAPINVAL, to be set on SF_SNAPSHOT inodes when
the snapshot is invalid.
Set SF_SNAPSHOT | SF_SNAPINVAL early when initializing a snapshot indode,
so that quota are bypassed for allocations on this inode.
Set SF_SNAPSHOT | SF_SNAPINVAL (instead of clearing SF_SNAPSHOT) when
expuge()ing a snapshot inode, so that userland tools working on the
snapshot (e.g. fsck or dump) can properly handle this inode.

The main point at this time is to have fsck_ffs -X properly compute quotas;
as a bonus persistent snapshots files won't show up in a dump(8) from a
snapshot.

This may also help speeding up taking snapshots, by bypassing expuge()
for snapshot inodes completely (but this needs more thoughs).

Support rest of file types in vtype -> s_ifmt

(pooka)

Support mount/unmount too.  So, things are now generally at a stage
where you can mount a file system with a userspace server *without*
it having to go through puffs.

Say, you first start a server with ffs capability and map a host
ffs image into it:

rump_server -lrumpvfs -lrumpfs_ffs \
    -d key=/ffsimg,hostpath=ffs2.img,size=e unix:///tmp/ffsserv

Then, configure your shell to talk to the rump server:

setenv RUMP_SERVER unix:///tmp/ffsserv
setenv LD_PRELOAD /usr/lib/librumphijack.so

Create a mountpoint and mount the file system:

pain-rustique:60:~> sh
$ cd /rump
$ ls
dev
$ ls -l
total 1
drwxr-xr-x  2 root  wheel  512 Feb 17 18:00 dev
$ mkdir mnt
$ mount_ffs /ffsimg /rump/mnt
mount_ffs: Warning: realpath /ffsimg: No such file or directory
$ df -h mnt
Filesystem        Size      Used      Avail %Cap Mounted on

Filesystem        Size      Used      Avail %Cap Mounted on
rumpfs            1.0K      1.0K        0B 100% /

(note, you need -R to umount due to various degrees of unsuccesful
magic it attempts to perform without it)

The decompressor in sys/net/zlib.c has a bug: It returns Z_BUF_ERROR after
a successful decompression in rare cases. A necessary but not sufficient
condition seems to be that the decompressed data end exactly at the end
of an allocated output buffer. (I can reproduce this reliably with
a userland program built against kernel zlib. Userland libz is much
newer and not affected.)
Since kernel zlib is based on an old version and heavily modified, I don't
dare to touch it. So catch this case in the wrapper.
Being here, reorder deflate/inflate error handling and add comments
to make understandable what is tested and why.

Sync with HEAD

(bouyer)

In case dup2(n, n+FDOFF) is done, the caller thinks there are two
distinct file descriptors, but the rump kernel thinks they are both
the same.  Now, if either one is closed by the application, "both"
will be closed in the rump kernel.  To fix this, maintain an
alias-mask.  It's not a perfect solution, though (consider e.g.
F_SETFL).  Maybe we should actually dup the fd and maintain a
mapping table?

Also, prevent the host from opening file descriptors onto the places
in the fd namespace that have been dupped.

These together fix "cat < /rump/foo" in a hijacked /bin/sh.
(the first one makes sure stdin is open in cat and the second one
makes sure it doesn't try to cat something from /usr/share/locale
instead of stdin)

Tell copyfd if the caller wants the exact tofd to just fd >= tofd.

ACPICA 20101209:

Completed the major overhaul of the GPE support code that was begun in July
2010. Major features include: removal of _PRW execution in ACPICA (host
executes _PRWs anyway), cleanup of "wake" GPE interfaces and processing,
changes to existing interfaces, simplification of GPE handler operation, and
a handful of new interfaces:

    AcpiUpdateAllGpes
    AcpiFinishGpe
    AcpiSetupGpeForWake
    AcpiSetGpeWakeMask

ACPICA 20100331:

Completed a major update for the GPE support in order to improve support for
shared GPEs and to simplify both host OS and ACPICA code. Added a reference
count mechanism to support shared GPEs that require multiple device drivers.
Several external interfaces have changed. One external interface has been
removed. One new external interface was added. Most of the GPE external
interfaces now use the GPE spinlock instead of the events mutex (and the
Flags parameter for many GPE interfaces has been removed.) See the updated
ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, Rafael
Wysocki. ACPICA BZ 831.

Changed:
    AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus
Removed:
    AcpiSetGpeType
New:
    AcpiSetGpe

ACPICA 20100702:

Implemented several updates to the recently added GPE reference count
support. The model for "wake" GPEs is changing to give the host OS complete
control of these GPEs. Eventually, the ACPICA core will not execute any _PRW
methods, since the host already must execute them. Also, additional changes
were made to help ensure that the reference counts are kept in proper
synchronization with reality. Rafael J. Wysocki.

1) Ensure that GPEs are not enabled twice during initialization.
2) Ensure that GPE enable masks stay in sync with the reference count.
3) Do not inadvertently enable GPEs when writing GPE registers.
4) Remove the internal wake reference counter and add new AcpiGpeWakeup
interface. This interface will set or clear individual GPEs for wakeup.
5) Remove GpeType argument from AcpiEnable and AcpiDisable. These interfaces
are now used for "runtime" GPEs only.
