In virFileOperation, the parent does a fallback to a non-fork
attempt if it detects that the child returned EACCES.  However,
the child was calling _exit(-EACCES), which does _not_ appear
as EACCES in the parent.

* src/util/util.c (virFileOperation): Correctly pass EACCES from
child to parent.

virSecurityDAC{Set,Restore}ChardevCallback expect virSecurityManagerPtr,
but are passed virDomainObjPtr instead. This makes
virSecurityDACSetChardevLabel set a wrong uid/gid on chardevs. This
patch fixes this behaviour.

This fixes a possible crash of libvirtd during its startup. When qemu
driver reconnects to running domains, it iterates over all domain
objects in a hash. When reconnecting to an associated qemu monitor
fails and the domain is transient, it's immediately removed from the
hash. Despite the fact that it's explicitly forbidden to do so. If
libvirtd is lucky enough, virHashForEach will access random memory when
the callback finishes and the deamon will crash.

Since it's trivial to fix virHashForEach to allow removal of hash
entries while iterating through them, I went this way instead of fixing
qemuReconnectDomain callback (and possibly others) to avoid deleting the
entries.

Replace the 'Unknown failure' error message with something a
little bit more descriptive.

* src/util/virterror.c: Improve error message

qemudDomainSaveImageStartVM was evil - it closed the incoming fd
argument on some, but not all, code paths, without informing the
caller about that action.  No wonder that this resulted in
double-closes: https://bugzilla.redhat.com/show_bug.cgi?id=672725

signature, to avoid double-close.

When a SPICE or VNC graphics controller is present, and sound is
piggybacked over a channel to the graphics device rather than
directly accessing host hardware, then there is no need to grant
host hardware access to that qemu process.

* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Prevent sound with
spice, and with vnc when vnc_allow_host_audio is 0.

The kill() function doesn't exist on Win32, so it needs to be
checked for at build time & code disabled in cgroups

* configure.ac: Check for kill()

this is the patch to add support for multiple serial ports to the
libvirt Xen driver. It support both old style (serial = "pty") and
new style (serial = [ "/dev/ttyS0", "/dev/ttyS1" ]) definition and
tests for xml2sexpr, sexpr2xml and xmconfig have been added as well.

Written and tested on RHEL-5 Xen dom0 and working as designed but
the Xen version have to have patch for RHBZ #614004 but this patch
is for upstream version of libvirt.

Also, this patch is addressing issue described in RHBZ #670789.

Relax the restriction that the hash table key must be a string
by allowing an arbitrary hash code generator + comparison func
to be provided

Since the deallocator is passed into the constructor of
a hash table it is not desirable to pass it into each
function again. Remove it from all functions, but provide
a virHashSteal to allow a item to be removed from a hash
table without deleteing it.

Using the 'personality(2)' system call, we can make a container

Remove the <stdbool.h> header from all source files / headers
and just put it into internal.h

* src/internal.h: Add <stdbool.h>

This is done for two reasons:
- we are getting very close to 64 flags which is the maximum we can use
  with unsigned long long
- by using LL constants in enum we already violates C99 constraint that
  enum values have to fit into int

The new name complies more with the fact that it contains a set of
qemuCapsFlags.

Three new functions (qemuCapsSet, qemuCapsClear, and qemuCapsGet) were
introduced replacing direct bit operations.

The new names comply more with the fact that they are all members of
enum qemuCapsFlags.

When spawning 'init' in the container, set

  LIBVIRT_LXC_UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
  LIBVIRT_LXC_NAME=YYYYYYYYYYYY

to allow guest software to detect & identify that they
are in a container

  LIBVIRT_LXC_NAME env vars

Current code does an IFF_UP on a 8021Qbh interface immediately after a port
profile set. This is ok in most cases except when its the migration prepare
stage. During migration we want to postpone IFF_UP'ing the interface on the
destination host until the source host has disassociated the interface.
This patch moves IFF_UP of the interface to the final stage of migration.
The motivation for this change is to postpone any addr registrations on the
destination host until the source host has done the addr deregistrations.

While at it, for symmetry with associate move ifDown of a 8021Qbh interface
to before disassociate
