Currently, QEMU's iotests rely on /usr/bin/env to start the correct
Python (that is, at least Python 2.4, but not 3). On systems where
Python 3 is the default, the user has no clean way of making the iotests
use the correct binary.

This commit makes the iotests use the Python selected by configure.

If the very first allocation has a length of 0, the free_cluster_index
is still 0 after the for loop, which means that subtracting one from it
will underflow and signal an invalid range of clusters by returning
-EFBIG. However, there is no such range, as its length is 0.

Fix this by preventing underflows on free_cluster_index during the
check.

Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Only notify spice-server about migration events in case we got
target host information beforehand.  So we kick the seamless spice
client migration only in case a actual live migration happens, not
when libvirt uses live-migration-to-file for snapshotting.
Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

In case no listening address was specified, "info spice" reports
"0.0.0.0" as address.  Which is incorrect in case spice is listening
on ipv6.  Replace it by a wildcard "*" to indicate it is not limited
to a specific address.

Note:  Being more specific is not possible without extending the
spice-server api.  The socket is handled by spice-server not
qemu, so qemu can't easily figure the actual socket address.

Commit 2e679780 replaced strncpy() with pstrcpy()
in one place in libcacard.  This is a qemu-specific function,
while libcacard is a stand-alone library (or tries to be).
But since we know the exact length of the string to copy,
and know that it definitely will fit in the destination
buffer, use memcpy() instead, and null-terminate the string
after that.

An alternative is to use g_strlcpy() or strncpy(), but memcpy()
is more than adequate in this place.

glib >= 2.31 always enables thread support and g_thread_supported()
is #defined to 1, there's no need to call g_thread_init() anymore,
and it definitely does not need to report error which never happens.

differently.

The test_path binary is (unlike the other test binaries in tests/tcg)
actually intended to be compiled with the same compiler used to build
the main QEMU executables. It actually #includes a number of the
QEMU source files in an attempt to unit-test the util/path.c functions,
and so if it is not compiled with the same compiler used by configure
to set CONFIG_ settings then it is liable to fail to build.
Fix the makefile to build it with the default C compiler rules, not
CC_I386, and fix the test itself not to include a lot of unnecessary
trace related source files which cause the build to fail if the trace
backend is anything other than 'simple'.

Implement discard support for xen_disk. It makes use of the existing
discard code in qemu.

The discard support is enabled unconditionally. The tool stack may
provide a property "discard-enable" in the backend node to optionally
disable discard support.  This is helpful in case the backing file was
intentionally created non-sparse to avoid fragmentation.
