* src/qemu/qemu_driver.c: Remove debugging fprintf() calls
  accidentally left in code

* src/qemu/qemu_driver.c (qemudDomainSetVcpus): Avoid NULL-deref
upon unknown UUID.  Call qemuDomainObjBeginJob(vm) only after
ensuring that vm != NULL, not before.  This potential NULL-deref
was introduced by commit 2c555d87.

This reverts commit 2d550542.

The patch worked for incremental builds, but broke fresh
builds, because it interfered with automake's automatic
dependency generation.  Until I figure out how to make
automake do what we want, I'd rather leave cygwin broken
but fresh Linux builds working.

make[3]: *** No rule to make target `-lxml2', needed by `libvirt.la'.  Stop.

Due to treating the wrong string as a dependency.

* src/Makefile.am (libvirt_la_DEPENDENCIES): Depend only on
locally-built file, not on strings that might resolve as '-lxml2'.

This adds a missing driver lock in the qemu driver to protect
the list of domains.

The code specifies driver->cacheDir as the format string,
but it usually doesn't contain '%s', so the subsequent
argument, "/qemu.mem.XXXXXX", is always ignored.

The patch fixes the misuse.

Setting dynamic_ownership=0 in /etc/libvirt/qemu.conf prevents
libvirt's DAC security driver from setting uid/gid on disk
files when starting/stopping QEMU, allowing the admin to manage
this manually. As a side effect it also stopped setting of
uid/gid when saving guests to a file, which completely breaks
save when QEMU is running non-root. Thus saved state labelling
code must ignore the dynamic_ownership parameter

* src/qemu/qemu_security_dac.c: Ignore dynamic_ownership=0 when
  doing save/restore image labelling

When QEMU runs with its disk on NFS, and as a non-root user, the
disk is chownd to that non-root user. When migration completes
the last step is shutting down the QEMU on the source host. THis
normally resets user/group/security label. This is bad when the
VM was just migrated because the file is still in use on the dest
host. It is thus neccessary to skip the reset step for any files
found to be on a shared filesystem

* src/libvirt_private.syms: Export virStorageFileIsSharedFS
* src/util/storage_file.c, src/util/storage_file.h: Add a new
  method virStorageFileIsSharedFS() to determine if a file is
  on a shared filesystem (NFS, GFS, OCFS2, etc)
* src/qemu/qemu_driver.c: Tell security driver not to reset
  disk labels on migration completion
* src/qemu/qemu_security_dac.c, src/qemu/qemu_security_stacked.c,
  src/security/security_selinux.c, src/security/security_driver.h,
  src/security/security_apparmor.c: Add ability to skip disk
  restore step for files on shared filesystems.

The cgroups ACL code was only allowing the primary disk image.
It is possible to chain images together, so we need to search
for backing stores and add them to the ACL too. Since the ACL
only handles block devices, we ignore the EINVAL we get from
plain files. In addition it was missing code to teardown the
cgroup when hot-unplugging a disk

* src/qemu/qemu_driver.c: Allow backing stores in cgroup ACLs
  and add missing teardown code in unplug path

If the IO error event does not include a reason, then there
is a possible crash dispatching the event

* src/conf/domain_event.c: Missing check for a NULL reason before
  strduping allows for a crash

QEMU is gaining a new monitor command netdev_add for hotplugging
NICs using the netdev backend code. We already support this on
the command this, though it is disabled. This adds support for
hotplug too, also to remain disabled until 0.13 QEMU is released

* src/qemu/qemu_driver.c: Support netdev hotplug for NICs
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
  src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h,
  src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add
  support for netdev_add and netdev_remove commands

* src/datatypes.c: Use correct word.

When closing a monitor using qemuMonitorClose(), we are aware of
the possibility the monitor is still being used somewhere:

    /* NB: ordinarily one might immediately set mon->watch to -1
     * and mon->fd to -1, but there may be a callback active
     * that is still relying on these fields being valid. So
     * we merely close them, but not clear their values and
     * use this explicit 'closed' flag to track this state */

but since we call virEventAddHandle() on that monitor without increasing
its ref counter, the monitor is still freed which makes possible users
of it quite unhappy. The unhappiness can lead to a hang if qemuMonitorIO
tries to lock mutex which no longer exists.

First calling REMOTE_PROC_CLOSE and then removing watches might lead to
a hang as HANGUP event can be triggered before the watches are actually
removed but after virConnectPtr is already freed. As a result of that
remoteDomainEventFired() would try to lock uninitialized mutex, which
would hang for ever.

Continuation of earlier patches to fix LIB_PTHREAD, only
triggered by ./configure --with-xen-proxy (a la autobuild.sh).

* proxy/Makefile.am (libvirt_proxy_LDADD): Add LIB_PTHREAD.

Product and vendor values were swapped in the XML, which made virt-manager
PCI device listing kinda useless.

* .gnulib: Update to latest.
* bootstrap.conf (gnulib_modules): Import netdb.

* bootstrap.conf (gnulib_modules): Use gettext-h, not gettext,
since the latter drags in a depedency on gettext 0.18.
Suggested by Bruno Haible.

* tests/virsh-schedinfo: This test sets PATH internally, just in
case you're running it manually.  Normally, the PATH setting from
tests/Makefile.am's TESTS_ENVIRONMENT is sufficient.  Prepend the
correct directory, and take advantage of the PATH setting in one
more case.

Allow debugging of GNUTLS interactions by setting

For example, virsh -c test:///default schedinfo 1 --set P=k would
mistakenly exit successfully, giving no indication that it had failed

* tools/virsh.c (cmdSchedInfoUpdate): Fix typo in a diagnostic:
s/an long long/a long long/.  One in a comment, too.

* src/util/macvtap.c (delMacvtap): Fix documentation.

* src/Makefile.am (remote_protocol-structs): Ensure file lives in srcdir.

* docs/Makefile.am (ChangeLog.html.in, %.html.tmp, %.html)
(html/index.html, $(devhelphtml)): Avoid spurious subshells.

Some shells warn about missing programs before redirection;
the idiomatic way to silence them is to run the program check
inside a subshell, with the redirections outside the subshell.
But a subshell is only needed in places where it is reasonable
to expect the use of such a noisy shell in the first place.

* src/Makefile.am (remote_protocol-structs): Use subshell, for
FreeBSD 8.0 /bin/sh.
* cfg.mk (sc_preprocessor_indentation): Avoid subshell, since the
only users running cfg.mk can be assumed to have decent tools.

For printf("%*s",foo,bar), clang complains if foo is not int:

warning: field width should have type 'int', but argument has
type 'unsigned int' [-Wformat]

* src/conf/storage_encryption_conf.c
(virStorageEncryptionSecretFormat, virStorageEncryptionFormat):
Use correct type.
* src/conf/storage_encryption_conf.h (virStorageEncryptionFormat):
Likewise.

Now, if you update remote_protocol.x without also updating
remote_protocol-structs to match, then "make check" will fail.
* src/Makefile.am (remote_protocol-structs): Extract list of
structs and member names from remote_protocol.o.
(check-local): Depend on it.
* src/remote_protocol-structs: New file.

Right now, mingw32-portablexdr is not available in Fedora, but is
present in fedora-mingw.git.  With that package, plus
redhat-rpm-config and this patch, it is once again possible to build
mingw32-libvirt from a Fedora 12 host.

* mingw32-libvirt.spec.in (__debug_install_post): Override.
(%files): Mention recent additions.

This reverts commit b5b8a6db.

That commit was not necessary. The problem is fixed by commit
0e9b3a26, but I didn't rebuild
it properly after pulling in the commit and didn't notice it.

Per automake, LDFLAGS is used early in the line, and LIBADD
(libraries) or LDADD (programs) is used late.  On platforms like
cygwin, without lazy linking, this order matters.  Therefore, libtool
commands, -L, and similar should be in LDFLAGS, but -l should be in
L*ADD.

* src/Makefile.am (*_LDFLAGS): Move libraries...
(*_LIBADD): ...to their LIBADD counterpart.

* src/Makefile.am: Fix some space-tab issues.

Link virt-aa-helper explicitly with pthread. This is at least
required on Ubuntu 10.04.

* src/Makefile.am (libvirt_util_la_LDFLAGS): Add $(LIB_PTHREAD),
required, now that we're using gnulib's pthread module.

Change 965466c1 added a new field to struct remote_error, which broke
the RPC protocol. Fortunately the new field is unused, so this change
simply removes it again.

* src/remote/remote_protocol.(c|h|x): Remove remote_nwfilter from struct
  remote_error

With the introduction of the generic qemu device model, unplugging
SCSI disks works like a charm, so support it in libvirt.

* src/qemu/qemu_driver.c: Add qemudDomainDetachSCSIDiskDevice() to do the
  unplugging, extend qemudDomainDetachDeviceAdd().
