b7d4c300c3 Add new internal domain events APIs for handling other event types
The current internal domain events API tracks callbacks based on
the function pointer, and only supports lifecycle events. This
adds new internal APIs for registering callbacks for other event
types. These new APIs are postfixed with the word 'ID' to indicate
that they operated based on event ID, instead of hardcoded to
lifecycle events

* src/conf/domain_event.c, src/conf/domain_event.h,
  src/libvirt_private.syms: Add new APIs for handling callbacks
  for non-lifecycle events

747c536370 Refactor domain events to handle multiple event types
The internal domain events APIs are designed to handle the lifecycle
events. This needs to be refactored to allow arbitrary new event
types to be handled.

 * The signature of virDomainEventDispatchFunc changes to use
   virConnectDomainEventGenericCallback instead of the lifecycle
   event specific virConnectDomainEventCallback
 * Every registered callback gains a unique ID to allow its
   removal based on ID, instead of function pointer
 * Every registered callback gains an 'eventID' to allow callbacks
   for different types of events to be distinguished
 * virDomainEventDispatch is adapted to filter out callbacks
   whose eventID does not match the eventID of the event being
   dispatched
 * virDomainEventDispatch is adapted to filter based on the
   domain name and uuid, if this filter is set for a callback.
 * virDomainEvent type/detail fields are moved into a union to
   allow different data fields for other types of events to be
   added later

* src/conf/domain_event.h, src/conf/domain_event.c: Refactor
  to allow handling of different types of events
* src/lxc/lxc_driver.c, src/qemu/qemu_driver.c,
  src/remote/remote_driver.c, src/test/test_driver.c,
  src/xen/xen_driver.c: Change dispatch function signature
  to use virConnectDomainEventGenericCallback

ea7dc33786 Make internal domain events struct definitions private
The virtual box driver was directly accesing the domain events
structs instead of using the APIs provided. To prevent this kind
of abuse, make the struct definitions private, forcing use of the
internal APIs. This requires adding one extra internal API.

* src/conf/domain_event.h, src/conf/domain_event.c: Move
  virDomainEventCallback and virDomainEvent structs into
  the source file instead of header
* src/vbox/vbox_tmpl.c: Use official APIs for dispatching domain
  events instead of accessing structs directly.

4445723811 Introduce a new public API for domain events
The current API for domain events has a number of problems

 - Only allows for domain lifecycle change events
 - Does not allow the same callback to be registered multiple times
 - Does not allow filtering of events to a specific domain

This introduces a new more general purpose domain events API

  typedef enum {
     VIR_DOMAIN_EVENT_ID_LIFECYCLE = 0,       /* virConnectDomainEventCallback */
      ...more events later..
  }

  int virConnectDomainEventRegisterAny(virConnectPtr conn,
                                       virDomainPtr dom, /* Optional, to filter */
                                       int eventID,
                                       virConnectDomainEventGenericCallback cb,
                                       void *opaque,
                                       virFreeCallback freecb);

  int virConnectDomainEventDeregisterAny(virConnectPtr conn,
                                         int callbackID);

Since different event types can received different data in the callback,
the API is defined with a generic callback. Specific events will each
have a custom signature for their callback. Thus when registering an
event it is neccessary to cast the callback to the generic signature

eg

  int myDomainEventCallback(virConnectPtr conn,
                            virDomainPtr dom,
                            int event,
                            int detail,
                            void *opaque)
  {
    ...
  }

  virConnectDomainEventRegisterAny(conn, NULL,
                                   VIR_DOMAIN_EVENT_ID_LIFECYCLE,
                                   VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback)
                                   NULL, NULL);

The VIR_DOMAIN_EVENT_CALLBACK() macro simply does a "bad" cast
to the generic signature

5edaf95599 esx: Make the conf parser compare names case insensitive in VMX mode
The keys of entries in a VMX file are case insensitive. Both scsi0:1.fileName
and scsi0:1.filename are valid. Therefore, make the conf parser compare names
case insensitive in VMX mode to accept every capitalization variation.

Also add test cases for this.

f66636e3ca vbox: Fix segfault on empty device source
<source file=''/> results in def->disks[i]->src == NULL. But
vboxDomainDefineXML and vboxDomainAttachDevice didn't check
def->disks[i]->src for NULL and expected it to be a valid string.

Add checks for def->disks[i]->src != NULL to fix the segfault.

8a7783c163 tests: Don't add extra padding if counter mod 40 is 0
This change only affects the output of tests that have an exact
multiple of 40 test cases. For example the domainschematest currently:

TEST: domainschematest
      ........................................ 40
      ........................................ 80
      ........................................ 120
      ........................................ 160
      ........................................                                         200 OK
PASS: domainschematest

It outputs additional 40 spaces on the last line.

The domainschematest output is fixed by the change in test-lib.sh. The
change in testutils.c fixes this for tests written in C. Currently no
C test has an exact multiple of 40 test cases, but I checked it and
the same problem exists there.

This patch stops that in both cases.

c390bcfec5 virDomainDiskDefAssignAddress: return int, not void
Before, this function would blindly accept an invalid def->dst

Now, this function returns -1 upon failure.

Even if gnulib can provide stubs, it won't help that much. So just

client side, so this is fine for MinGW builds.

d304352b19 esx: Generate method mappings via macros
This is actually a consequence of the reworked required parameter

The required parameter checking for the mapped methods parameter was
done in the (de)serialize functions before. Now it's explicitly done
in the mapped method itself.

09fafa1e21 Avoid libvirtd crash when cgroups is not configured on host
Invoking virDomainSetMemory() on lxc driver results in libvirtd
segfault when cgroups has not been configured on the host.

Ensure driver->cgroup is non-null before invoking
virCgroupForDomain().  To prevent similar segfaults in the future,
ensure driver parameter to virCgroupForDomain() is non-null before
dereferencing.
