fa1e4759db Move qemuMonitorEscape + migrate status enum into shared monitor code
The qemuMonitorEscape() method, and the VIR_ENUM for migration
status will be needed by the JSON monitor too, so move that code
into the shared qemu_monitor.c file instead of qemu_monitor_text.c

* src/qemu/qemu_monitor.h: Declare qemuMonitorMigrationStatus enum
  and qemuMonitorEscapeArg and qemuMonitorEscapeShell methods
* src/qemu/qemu_monitor.c: Implement qemuMonitorMigrationStatus enum
  and qemuMonitorEscapeArg and qemuMonitorEscapeShell methods
* src/qemu/qemu_monitor_text.c: Remove above methods/enum

79533da1b3 Fix crash when deleting monitor while a command is in progress
If QEMU shuts down while we're in the middle of processing a
monitor command, the monitor will be freed, and upon cleaning
up we attempt to do  qemuMonitorUnlock(priv->mon) when priv->mon
is NULL.

To address this we introduce proper reference counting into
the qemuMonitorPtr object, and hold an extra reference whenever
executing a command.

* src/qemu/qemu_driver.c: Hold a reference on the monitor while
  executing commands, and only NULL-ify the priv->mon field when
  the last reference is released
* src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c: Add reference
  counting to handle safe deletion of monitor objects

9428f2ced6 Introduce a simple API for handling JSON data
This introduces simple API for handling JSON data. There is
an internal data structure 'virJSONValuePtr' which stores a
arbitrary nested JSON value (number, string, array, object,
nul, etc).  There are APIs for constructing/querying objects
and APIs for parsing/formatting string formatted JSON data.

This uses the YAJL library for parsing/formatting from

 http://lloyd.github.com/yajl/

  for representing JSON data, and parsing/formatting it

81ea6e4d9f Tests for interface type/model configuration
add a set of tests for Xen interface type and model configurations

dddad4bcb4 Support for interface model='netfront'
Xen HVM guests with PV drivers end up with two network interfaces for
each configured interface. One of them being emulated by qemu and the
other one paravirtual. As this might not be desirable, the attached
patch provides a way for users to specify that only paravirtual network
interface should be presented to the guest.

The configuration was inspired by qemu/kvm driver, for which users can
specify model='virtio' to use paravirtual network interface.

The patch adds support for model='netfront' which results in
type=netfront instead of type=ioemu (or nothing for newer xen versions)
in guests native configuration. Xen's qemu ignores interfaces with
type != ioemu and only paravirtual network device will be seen in the
guest.

Four possible configuration scenarios follow:

- no model specified in domain's XML
    - libvirt will behave like before this change; it will set
      type=ioemu for HVM guests on xen host which is not newer than
      XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU
    - covered by existing tests

- PV guest, any model
    - no functional change, model is passed as is (and ignored by the
      hypervisor)
    - covered by existing tests (e.g., *-net-e1000.*)
- HVM guest, model=netfront
    - type is set to "netfront", model is not specified
    - covered by new *-net-netfront.* tests

- HVM guest, model != netfront
    - type is set to "ioemu", model is passed as is
    - covered by new *-net-ioemu.* tests

The fourth scenario feels like a regression for xen newer than
XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified
in their guest's configuration won't see a paravirtual interface in
their guests any more. On the other hand, the reason for specifying a
model is most likely the fact that they want to use such model which
implies emulated interface. Users of older xen won't be affected at all
as their xen provides paravirtual interface regardless of the type used.

- src/xen/xend_internal.c: add netfront support for the xend backend
- src/xen/xm_internal.c: add netfront support for the XM serialization too

63166a4e0c Add virIndexToDiskName and fix mapping gap
esxVMX_IndexToDiskName handles indices up to 701. This limit comes
from a mapping gap in virDiskNameToIndex:

  sdzy -> 700
  sdzz -> 701
  sdaaa -> 728
  sdaab -> 729

This line in virDiskNameToIndex causes this gap:

  idx = (idx + i) * 26;

Fixing it by altering this line to:

  idx = (idx + (i < 1 ? 0 : 1)) * 26;

Also add a new version of virIndexToDiskName that handles the inverse
mapping for arbitrary indices.

* src/esx/esx_vmx.[ch]: remove esxVMX_IndexToDiskName
* src/util/util.[ch]: add virIndexToDiskName and fix mapping gap

32f021f266 Fix event test timer checks on kernels with HZ=100
On kernels with HZ=100, the resolution of sleeps in poll() is
quite bad. Doing a precise check on the expiry time vs the
current time will thus often thing the timer has not expired
even though we're within 10ms of the expected expiry time. This
then causes another pointless sleep in poll() for <10ms. Timers
do not need to have such precise expiration, so we treat a timer
as expired if it is within 20ms of the expected expiry time. This
also fixes the eventtest.c test suite on kernels with HZ=100
