cc875b8372 hypervisor api: implement RPC calls for virNodeDeviceDetachFlags
This requires a custom function for remoteNodeDeviceDetachFlags,
because it is named *NodeDevice, but it goes through the hypervisor
driver rather than nodedevice driver, and so it uses privateData
instead of nodeDevicePrivateData. (It has to go through the hypervisor
driver, because that is the driver that knows about the backend drivers
that will perform the pci device assignment).

bb03636827 Make naming of remote procedures match API names exactly
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

39758e7567 remote: Wire up the remote protocol
Like virNodeDeviceCreateXML, virNodeDeviceLookupSCSIHostByWWN
has to be treated specially when generating the RPC codes. Also
new rules are added in fixup_name to keep the name SCSIHostByWWN.

d52add46ed api: Add API to tunnel a guest channel via stream
This patch adds a new API, virDomainOpenChannel, that uses streams to
connect to a virtio channel on a guest.  This creates a secure
communication channel between a guest and a libvirt client.

This behaves the same as virDomainOpenConsole, except on channels
instead of console/serial/parallel devices.

3d0130cbcc cpumap: optimize for clients that don't need online count
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.

* src/nodeinfo.c (nodeGetCPUMap): Avoid bitmap when not needed.
* src/remote/remote_protocol.x (remote_node_get_cpu_map_args):
Supply two separate flags for needed arguments.
* src/remote/remote_driver.c (remoteNodeGetCPUMap): Update
caller.
* daemon/remote.c (remoteDispatchNodeGetCPUMap): Likewise.
* src/remote_protocol-structs: Regenerate.

7ba5defb5a Add support for SUSPEND_DISK event
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.

055bbf45e4 resize: slightly alter signature
Our existing virDomainBlockResize takes an unsigned long long
argument; if that command is later taught a DELTA and SHRINK flag,
we cannot change its type without breaking API (but at least such
a change would be ABI compatible).  Meanwhile, the only time a
negative size makes sense is if both DELTA and SHRINK are used
together, but if we keep the argument unsigned, applications can
pass the positive delta amount by which they would like to shrink
the system, and have the flags imply the negative value.  So,
since this API has not yet been released, and in the interest of
consistency with existing API, we swap virStorageVolResize to
always pass an unsigned value.

* include/libvirt/libvirt.h.in (virStorageVolResize): Use unsigned
argument.
* src/libvirt.c (virStorageVolResize): Likewise.
* src/driver.h (virDrvStorageVolUpload): Adjust clients.
