Decouple the monitor code from the virDomainDefPtr structure
by moving the disk encryption lookup code back into the
qemu_driver.c file. Instead provide a function callback to
the monitor code which can be invoked to retrieve encryption
data as required.

* src/qemu/qemu_driver.c: Add findDomainDiskEncryption,
  and findVolumeQcowPassphrase. Pass address of the method
  findVolumeQcowPassphrase into qemuMonitorOpen()
* src/qemu/qemu_monitor.c: Associate a disk
  encryption function callback with the qemuMonitorPtr
  object.
* src/qemu/qemu_monitor_text.c: Remove findDomainDiskEncryption
  and findVolumeQcowPassphrase.

Introduce a new qemuDomainObjPrivate object which is used to store
the private QEMU specific data associated with each virDomainObjPtr
instance. This contains a single member, an instance of the new
qemuMonitorPtr object which encapsulates the QEMU monitor state.
The internals of the latter are private to the qemu_monitor* files,
not to be shown to qemu_driver.c

* src/qemu/qemu_conf.h: Definition of qemuDomainObjPrivate.
* src/qemu/qemu_driver.c: Register a functions for creating
  and freeing qemuDomainObjPrivate instances with the domain
  capabilities. Remove the qemudDispatchVMEvent() watch since
  I/O watches are now handled by the monitor code itself. Pass
  a new qemuHandleMonitorEOF() callback into qemuMonitorOpen
  to allow notification when the monitor quits.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Introduce
  the 'qemuMonitor' object. Temporarily add new APIs
  qemuMonitorWrite, qemuMonitorRead, qemuMonitorWaitForInput
  to allow text based monitor impl to perform I/O.
* src/qemu/qemu_monitor_text.c: Call APIs for reading/writing
  to monitor instead of accessing the file handle directly.

The qemu_driver.c code should not contain any code that interacts
with the QEMU monitor at a low level. A previous commit moved all
the command invocations out. This change moves out the code which
actually opens the monitor device.

* src/qemu/qemu_driver.c: Remove qemudOpenMonitor & methods called
  from it.
* src/Makefile.am: Add qemu_monitor.{c,h}
* src/qemu/qemu_monitor.h: Add qemuMonitorOpen()
* src/qemu/qemu_monitor.c: All code for opening the monitor

* src/util/threads.h, src/util/threads-pthread.c,
  src/libvirt_private.syms: Add virCondWaitUntil()

* src/util/threads-pthread.c: pthreads APIs do not set errno, instead
  the return value is the positive errno. Set errno based on the return
  value in the wrappers

* src/util/pci.c, src/util/pci.h: Make the pciDeviceList struct
  opaque to callers of the API. Add accessor methods for managing
  devices in the list
* src/qemu/qemu_driver.c: Update to use APIs instead of directly
  accessing pciDeviceList fields

* src/formatdomain.html.in: Add <channel> element documentation

* docs/formatdomain.html.in: refactors the existing character device
  documentation to make it explicit which directives configure the guest
  interface, and which configure the host interface.

As it was basically unimplemented and more confusing than useful
at the moment.
* src/libvirt_private.syms: remove from internal symbols list
* src/qemu/qemu_bridge_filter.c src/util/ebtables.c: remove code and
  one use of the unimplemented function

In case of an error the domains hash and the driver mutex may leak.

* src/opennebula/one_driver.c: free/destroy domains hash and driver
  mutex in error cases

It also demonstrates how to use the libvirt.openAuth() method.

* examples/python/Makefile.am: add esxlist.py to EXTRA_DIST
* examples/python/README: add some notes about esxlist.py
* examples/python/esxlist.py: the new example

- Make reading ID from file working for IDs > 127
- Fix inverse error check for writing ID to file
- Use feof() to distinguish EOF from real error of fread()
- Don't interpret libssh2 error codes as number of bytes

Also reset UUID to all 0 instead of all 48 (== '0') in phypUUIDTable_RemLpar()

phypNumDomainsGeneric() and phypListDomainsGeneric() return 0 in case
of an error. This makes it impossible to distinguish between an actual
error and no domains being defined on the hypervisor. It also turn the
no domains situation into an error. Return -1 in case of an error to
fix this problem.

* configure.in: add -L$libssh2_path to LIBS for the AC_TRY_LINK check

* src/network/bridge_driver.c: when exec'ing dnsmaq, if there are
  DHCP ranges defined, then compute and pass the --dhcp-lease-max
  deriving the maximum number of leases

* src/conf/network_conf.h: extend the structure to store the range
* src/conf/network_conf.c: before adding a range parse the IP addresses
  do some checking and keep the size

* src/util/network.c: getIPv4Addr() got broken when the input
  network address value got converted from network to host byte order

This is what virsh already expects when printing output, and what
'man cpuset' claims to support.

Use this function in the qemu, uml, lxc, and test drivers.

This patch is the result of running the following command in the docs
directory: sed -i 's/\t/        /g; s/\s*$//' *.html.in

* docs/*.html.in:convert tabs into 8 spaces and remove trailing whitespace

* src/qemu/qemu_conf.c: Update qemudBuildCommandLineChrDevStr to use a
  virBuffer

* src/qemu_qemu_conf.c: Cleanup usage of virBuffer in qemudBuildCommandLine

* src/internal.h (ATTRIBUTE_SENTINEL): New, it's a ggc feature and
  protected as such
* src/util/buf.c (virBufferStrcat): Use it.
* src/util/ebtables.c (ebtablesAddRemoveRule): Use it.
* src/util/iptables.c (iptableAddRemoveRule: Use it.
* src/util/qparams.h (new_qparam_set, append_qparams): Use it.
* docs/apibuild.py: avoid breaking the API generator with that new
  internal keyword macro

This matches the expected behavior of state drivers such as QEMU.

Performs changes needed when stopping a VM (which are currently duplicated
in several places, and forgotten in others).

* src/qemu/qemu_driver.c: in qemudDomainMigratePerform call
  doPeer2PeerMigrate for VIR_MIGRATE_PEER2PEER.

* src/util/network.c: Add htons and ntohs in virSocket(Get|Set)Port

* src/phyp/phyp_driver.[ch]: add new entry points and a number of
  cleanups

* include/libvirt/virterror.h src/util/virterror.c: add a new error
  VIR_ERR_CONFIG_UNSUPPORTED for valid but unsupported configuration options
* src/conf/domain_conf.c: Throw an error if guestfwd address isn't IPv4
  and cleanup a number of parsing return error values.

allows the following to be specified in a domain:
<channel type='pipe'>
  <source path='/tmp/guestfwd'/>
  <target type='guestfwd' address='10.0.2.1' port='4600'/>
</channel>

* proxy/Makefile.am: add network.c as dep of domain_conf.c
* docs/schemas/domain.rng src/conf/domain_conf.[ch]: extend the domain
  schemas and the parsing/serialization side for the new construct

QEmu support will add the following on the qemu command line:
 -chardev pipe,id=channel0,path=/tmp/guestfwd
 -net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0

* src/qemu/qemu_conf.c: Add argument output for channel
* tests/qemuxml2(argv|xml)test.c: Add test for <channel> domain syntax

* src/qemu/qemu_conf.h: defines a new QEMUD_CMD_FLAG_CHARDEV flag
* src/qemu/qemu_conf.c: parse the output for -chardev and set flag
  appropriately
