configure: Check that "libtool" is not the MacOSX one
The "libtool" binary on MacOSX is not GNU libtool, and doesn't support
anything like the same set of command line options. Test whether we
have accidentally picked this up (by looking for whether it handles

TLS support for VNC Websockets
Added TLS support to the VNC QEMU Websockets implementation.
VNC-TLS needs to be enabled for this feature to be used.
The required certificates are specified as in case of VNC-TLS
with the VNC parameter "x509=<path>".
If the server certificate isn't signed by a rooth authority it needs to
be manually imported in the browser because at least in case of Firefox
and Chrome there is no user dialog, the connection just gets canceled.
As a side note VEncrypt over Websocket doesn't work atm because TLS can't
be stacked in the current implementation. (It also didn't work before)
Nevertheless to my knowledge there is no HTML 5 VNC client which supports
it and the Websocket connection can be encrypted with regular TLS now so
it should be fine for most use cases.

vmdk: Add option to create zeroed-grain image
Add image create option "zeroed-grain" to enable zeroed-grain GTE
feature of vmdk sparse extents. When this option is on, header version
of newly created extent will be 2 and VMDK4_FLAG_ZERO_GRAIN flag bit

vmdk: add support for “zeroed‐grain” GTE
Introduced support for zeroed-grain GTE, as specified in Virtual Disk
Format 5.0[1].
Recent VMware hosted platform products support a new “zeroed‐grain”
grain table entry (GTE). The zeroed‐grain GTE returns all zeros on
read. In other words, the zeroed‐grain GTE indicates that a grain
in the child disk is zero‐filled but does not actually occupy space
in storage. A sparse extent with zeroed‐grain GTE has the following
in its header:
* SparseExtentHeader.version = 2
* SparseExtentHeader.flags has bit 2 set
Other than the new flag and the possibly zeroed‐grain GTE, version 2
sparse extents are identical to version 1. Also, a zeroed‐grain GTE
has value 0x1 in the GT table.

Wire up disabled wait a panicked event on s390
On s390 the disabled wait state indicates a state of attention.
For example Linux uses that state after a panic. Lets
put the system into panicked state.
An alternative implementation would be to state
disabled-wait <address> instead of pause in the action field.
(e.g. z/OS, z/VM and other classic OSes use the address of the
disabled wait to indicate an error code).

introduce a new qom device to deal with panicked event
pvpanic device is used to send guest panic event from guest to qemu.
When guest panic happens, pvpanic device driver will write a event
number to IO port 0x505(which is the IO port occupied by pvpanic device,
by default). On receiving the event, pvpanic device will pause guest
cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.

In rules.mak, "-I$(<D) -I$(@D)" was expanded to "-Idtc -I." when

a warning would be rarsed. To avoid it, add "-I$(<D) -I$(@D)" to
QEMU_INCLUDES instead of QEMU_CFLAGS so that QEMU_CFLAGS does not
