We observed that some threads can reach deadlock-ish state after they have Invoked into a control's UI thread. When it happens they are all in a waiting for join or in sleep state for very long time, although there should not be any deadlock situations.
It seems this has something to do with multiple parent controls and with which control we invoked on. This should not make a difference, because we have got one UI thread (for MainWindow) they should wait for, but we have seen it does.
The solution that fixed this issue was to invoke on the MainWindow instead of various controls (see a4fe507adf ).
This changeset is changing all our Invokes to invoke into MainWindow
instead of a control itself. (MainWindow's UI thread is the only UI thread
all Control is using in XenCenter)
This changeset should be in place until we have found the root cause or the exact reason for the above.

- Pool.HasGpu = Pool has at least one PGPU
- Pool.HasVGpu = Pool has at least one PGPU that HasVGpu
- PGPU.HasVGpu = PGPU has at least one supported_VGPU_type that is not pass-through

- Helpers.ClearwaterSp1OrGreater = API version is 2.1 or greater
The GPU dialogs are displayed as follows:
- GPU page on VM properties dialog: Visible only if VM.CanHaveGpu and the GPU feature not restricted (by licensing)
- GPU page on New VM Wizard: Visible only if VM.CanHaveGpu and the pool has GPU capability (Helpers.GpuCapability)
- GPU page on Pool properties dialog: Visible only if the pool has vGPU capability (Helpers.VGpuCapability)

Correction following code review: When a host collection changes, update all rows containing the hosts changed. This will cover the case when the License Manager shows all members of a pool on separate rows for pre-6.2 versions of XenServer.

The problem was that the License Manager was listening to PropertyChanged events on the master only, not on slaves.
When the master's properties change (e.g. edition) we update the row in the license manager; but in some cases a slave (or more) hasn't been updated yet (as it may be updated in another event.from) and we think that the pool is partially updated.
Our solution is to listen to Host BatchCollectionChanged event, which is triggered once per cache update for the host collection (it any property changed for any of the hosts).
The sleep in the ApplyLicenseEditionAction is not needed anymore, nor is the extra call to update the cell after the action is completed, because the cell is getting updated correctly on the BatchCollectionChanged event.

In some cases calling Control.Invoke() from a background thread causes that thread to go in a "sleep, wait, or join" mode, while waiting for Invoke to happen, although the UI thread is running normally.
If the Control is the MainWindow, it works as expected, but we've seen it happening while connecting or disconnecting from a large pool, on calling Invoke on controls like NavigationView, AlertSummaryPage, HistoryPage, etc.
To fix this, we call the Invoke on the MainWindow in all the places where we've seen the issue.
With this changes, the previous fix for CA-148245 (call RequestRefreshTreeView on CacheClearing event) is not needed anymore, so I removed that call.

2. "Close" should not be the default button when "Previous Section" or "Next Section" is enabled.
3. On WLB advanced settings page, the split line of pool audit granularity should extend and contract along with the size change of the form.

This fix corrects the following behaviour: when you have a VM with no affinity and you go into its Properties dialog,
XenCenter believes that a VM on a standalone host has to have that affinity, and greys out the "no affinity" radio button,
which has the effect of forcibly changing the affinity to the host, which a VM Admin is not allowed to do.
The correct behaviour is that if a VM already has no affinity, we don't grey out the radio button.
