field xXXXX. ie strip the leading 'vir' and lowercase any
leading uppercase letters.

A number of the remote procedure names did not match the
corresponding API names. For example, many lacked the
word 'CONNECT', others re-arranged the names. Update the
procedures so their names exactly match the API names.
Then remove the special case handling of these APIs in
the generator

Currently the server determines whether authentication of clients
is complete, by checking whether an identity is set. This patch
removes that lame hack and replaces it with an explicit method
for changing the client auth code

* daemon/remote.c: Update for new APis

Add the infrastructure for the libvirt-lxc.la library to

Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

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.

There's been a few bugs about an expected error from polkit:

https://bugzilla.redhat.com/show_bug.cgi?id=873799
https://bugzilla.redhat.com/show_bug.cgi?id=872166

The error is:

Authorization requires authentication but no agent is available.

The error means that polkit needs a password, but there is no polkit
agent registered in your session. Polkit agents are the bit of UI that
pop up and actually ask for your password.

Preface the error with the string 'polkit:' so folks can hopefully
make more sense of it.

This will simplify the refactoring of the ESX storage driver to support
a VMFS and an iSCSI backend.

One of the tasks the storage driver needs to do is to decide which backend
driver needs to be invoked for a given request. This approach extends
virStoragePool and virStorageVol to store extra parameters:

1. privateData: stores pointer to respective backend storage driver.
2. privateDataFreeFunc: stores cleanup function pointer.

virGetStoragePool and virGetStorageVol are modfied to accept these extra
parameters as user params. virStoragePoolDispose and virStorageVolDispose
checks for cleanup operation if available.

The private data pointer allows the ESX storage driver to store a pointer
to the used backend with each storage pool and volume. This avoids the need
to detect the correct backend in each storage driver function call.

It turns out that calling virNodeGetCPUMap(conn, NULL, NULL, 0)
is both useful, and with Viktor's patches, common enough to
optimize.  Since this interface hasn't been released yet, we
can change the RPC call.

A bit more background on the optimization - learning the cpu count
is a single file read (/sys/devices/system/cpu/possible), but
learning the number of online cpus can possibly trigger a file
read per cpu, depending on the age of the kernel, and all wasted
if the caller passed NULL for both arguments.

This patch adds support for SUSPEND_DISK event; both lifecycle and
separated.  The support is added for QEMU, machines are changed to
PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes
to shut-off.  This and much more needs to be done in order for libvirt
to work with transient devices, wake-ups etc.  This patch is not
aiming for that functionality.

Make virNetSASLContext and virNetSASLSession use virObject APIs

Daemon uses the following pattern when dispatching APIs with typed
parameters:

    VIR_ALLOC_N(params, nparams);
    virDomain*(dom, params, &nparams, flags);
    virTypedParameterArrayClear(params, nparams);

In case nparams was originally set to 0, virDomain* API would fill it
with the number of typed parameters it can provide and we would use this
number (rather than zero) to clear params. Because VIR_ALLOC* returns
non-NULL pointer even if size is 0, the code would end up walking
through random memory. If we were lucky enough and the memory contained
7 (VIR_TYPED_PARAM_STRING) at the right place, we would try to free a
random pointer and crash.

Let's make sure params stays NULL when nparams is 0.
