glib: fix g_poll early timeout on windows
g_poll has a problem on Windows when using
timeouts < 10ms, in glib/gpoll.c:
/* If not, and we have a significant timeout, poll again with

* one event, or only for messages. We ignore timeouts less than
* ten milliseconds as they are mostly pointless on Windows, the

if (retval == 0 && (timeout == INFINITE || timeout >= 10))
retval = poll_rest (poll_msgs, handles, nhandles, fds, nfds, timeout);
so whenever g_poll is called with timeout < 10ms it does
a quick poll instead of wait, this causes significant performance
degradation of QEMU, thus we should use WaitForMultipleObjectsEx
directly

block: qemu-iotests - add common.qemu, for bash-controlled qemu tests
This creates some common functions for bash language qemu-iotests
to control, and communicate with, a running QEMU process.
4 functions are introduced:
1. _launch_qemu()
This launches the QEMU process(es), and sets up the file
descriptors and fifos for communication. You can choose to
launch each QEMU process listening for either QMP or HMP
monitor. You can call this function multiple times, and
save the handle returned from each. The returned handle is
in $QEMU_HANDLE. You must copy this value.
Commands 2 and 3 use the handle received from _launch_qemu(), to talk
to the appropriate process.
2. _send_qemu_cmd()
Sends a command string, specified by $2, to QEMU. If $3 is
non-NULL, _send_qemu_cmd() will wait to receive $3 as a
required result string from QEMU. Failure to receive $3 will
cause the test to fail. The command can optionally be retried
$qemu_cmd_repeat number of times. Set $qemu_error_no_exit
to not force the test the fail on exit; in this case,
$QEMU_STATUS[$1] will be set to -1 on failure.
3. _timed_wait_for()
Waits for a response, for up to a default of 10 seconds. If
$2 is not seen in that time (anywhere in the response), then
the test fails. Primarily used by _send_qemu_cmd, but could
be useful standalone, as well. To prevent automatic exit
(and therefore test failure), set $qemu_error_no_exit to a
non-NULL value. If $silent is a non-NULL value, then output
to stdout will be suppressed.
4. _cleanup_qemu()
Kills the running QEMU processes, and removes the fifos.

on this fact we need to make sure that errno is set on each failure.

block: Fix open flags with BDRV_O_SNAPSHOT
The immediately visible effect of this patch is that it fixes committing
a temporary snapshot to its backing file. Previously, it would fail with
a "permission denied" error because bdrv_inherited_flags() forced the
backing file to be read-only, ignoring the r/w reopen of bdrv_commit().
The bigger problem this revealed is that the original open flags must
actually only be applied to the temporary snapshot, and the original
image file must be treated as a backing file of the temporary snapshot
and get the right flags for that.

qemu-img: sort block formats in help message
The help message for qemu-img lists the supported block formats, of
which there are 27 as of version 2.0.50. The formats are printed in
the order of their driver's position in a linked list, which appears
random. This patch prints the formats in sorted order, making it
easier to read and to find a specific format in the list.
[Added suggestions from Fam Zheng <famz@redhat.com> to declare variables
at the top of the scope in help() and to omit explicit cast for void*
opaque.

iotests: Use configured python
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

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

qcow2: Fix alloc_clusters_noref() overflow detection
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.

libcacard: replace pstrcpy() with memcpy()
Commit
2e679780ae86c6ca8 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.

There was already a forward declaration using 'static',

arch_init: Be sure of only one exit entry with DPRINTF() for ram_load()
When DPRINTF() has effect, the original author wants to print all
ram_load() calling results. So need use 'goto' instead of 'return'
within ram_load(), just like other areas have done.

tests/tcg: Fix compilation of test_path
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'.

configure: remove bashism
Commit
e26110cfc67d48 added a check for shacmd to create a hash
for modules. This check in configure is using bash construct &>
to redirect both stdout and stderr, which does fun things on some
shells. Get rid of it, use standard redirection instead.

xen_disk: add discard support
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.
