Blktap2 is effectively dead code for a few years.
Notable changes in this patch:
0. Unhook blktap2 from build system
1. Now libxl no longer supports TAP disk backend, appropriate assertions
are added and some code paths now return ERROR_FAIL
2. Tap is no longer a supported backend in doc
3. Remove relevant entries in MAINTAINERS
A patch to actually remove blktap2 directory will come later.
Signed-off-by: Wei Liu <wei.liu2@citrix.com>
Acked-by: George Dunlap <George.Dunlap@eu.citrix.com>
---
This version is tested: libxl bails when trying to set backend to tap.
Other stuff works as usual.
Changes in v2:
1. Fix typo in commit message
2. Add George's Acked-by
3. Delete blktap2 entries in hgignore as well

The change to libxl seems OK to me, although:

What error message and error code do you get ? If we're removing
this, we should make sure that the error message makes sense.
All the rest is fine by me. But we should wait a bit more to see if
anyone objects IMO.

The error code is going to be ERROR_INVAL. The error message is going to
be:
Disk vdev=XXX, backend tap unsuitable because blktap not supported
no suitable backend for disk XXX
See libxl__device_disk_set_backend.

Considering it has been more than three weeks since I posted the first
version of this series and how close we are now to the freeze, I think
it is now time to push this series.
I will push this series now.
Lars, this should remove your work item to clean up the license of
blktap2.
Wei.

Ian said on IRC "considered it acked" (it referring to this patch), so I
will put his ack in while committing.
