31494974c4 qemu: fix QEMU_CAPS_NO_ACPI detection
In commit c4bbaaf8, caps->arch was checked uninitialized, rendering the
whole check useless.

This patch moves the conditional setting of QEMU_CAPS_NO_ACPI to
qemuCapsInitQMP, and removes the no longer needed exception for S390.

It also clears the flag for all non-x86 archs instead of just S390 in
qemuCapsInitHelp.

d514d7773c rpc: Check and message setsockopt()
Check status when attempting to set SO_REUSEADDR flag on outgoing connection
On failure, VIR_WARN(), but continue to connect. This code path is on the
sender side where the setting is just a hint and would only take effect if
the sender is overflowed with TCP connections.  Inability to set doesn't mean
failure to establish a connection.

In virLockSpaceProtocolDispatchCreateLockSpace() lockspace is also overwritten
in a similar manner resulting in the same Coverity message.

69218922e8 Allow for multi-level inheritance of virObject classes
Currently all classes must directly inherit from virObject.
This allows for arbitrarily deep hierarchy. There's not much
to this aside from chaining up the 'dispose' handlers from
each class & providing APIs to check types.

3d1596b048 Introduce an LXC specific public API & library
This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.

The actual APIs are

  int virDomainLxcOpenNamespace(virDomainPtr domain,
                                int **fdlist,
                                unsigned int flags);

  int virDomainLxcEnterNamespace(virDomainPtr domain,
                                 unsigned int nfdlist,
                                 int *fdlist,
                                 unsigned int *noldfdlist,
                                 int **oldfdlist,
                                 unsigned int flags);

which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.

NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.
