Introduced by 241cbc13, pushed under urgent rule.

Without these patch, there will be error like below if domain
is NULL.

error: invalid domain pointer in virDomainFree

Which is useless.

* src/qemu/qemu_command.c: s/VIR_ERR_NO_SUPPORT/VIR_ERR_CONFIG_UNSUPPORTED/

* src/qemu/qemu_driver.c: s/VIR_ERR_NO_SUPPORT/VIR_ERR_OPERATION_INVALID/

* src/qemu/qemu_process.c: s/VIR_ERR_NO_SUPPORT/VIR_ERR_OPERATION_INVALID/

s/VIR_ERR_NO_SUPPORT/VIR_ERR_OPERATION_INVALID/

Special case is changes on lxcDomainInterfaceStats, if it's not
implemented on the platform, prints error like:

    lxcError(VIR_ERR_OPERATION_INVALID, "%s",
             _("interface stats not implemented on this platform"));

As the function is supported by driver actually, error like
VIR_ERR_NO_SUPPORT is confused.

* src/qemu/qemu_monitor_text.c: Error like "this function is not
supported by the connection driver" is confused obviously.

It's strange that the command fails but without any error if one
specifies as not a number.

Now, bad key-code in send-key can cause segmentation fault in libvirt.
(example)
 % virsh send-key --codeset win32 12
   error: End of file while reading data: Input/output error

This is caused by overrun at scanning keycode array.

Fix it.

Systemtap 1.2 <sys/sdt.h> tried to expand STAP_PROBE3 into an
initialization:
  volatile __typeof__(arg) foo = arg;
but that fails if arg was declared as 'char arg[100]'.
Rather than make all callers to PROBE deal with the stupidity
of <sys/sdt.h>, we instead make PROBE cast away the problem.
Some of this preprocessor abuse copies ideas in src/libvirt.c.

* daemon/libvirtd.h (PROBE): Add casts to all arguments, using...
(VIR_ADD_CASTS, VIR_ADD_CAST, VIR_ADD_CAST2, VIR_ADD_CAST3)
(VIR_ADD_CAST_EXPAND, VIR_ADD_CAST_PASTE, VIR_COUNT_ARGS)
(VIR_ARG5, PROBE_EXPAND): New macros.
Reported by Wen Congyang.

Without this patch, invoking 'virsh >file 2>&1' results in
error messages appearing before normal output, even if they
occurred later in time than the normal output (since stderr
is unbuffered, but stdout waits until a full buffer).

* tools/virsh.c (print_job_progress, vshError): Flush between
stream transitions.
* tests/undefine: Test it.

Repetitive patterns should be factored.  The sign of a good
factorization is a change that kills 5x more lines than it adds :)

* src/conf/domain_conf.c (virDomainDeviceDefParse)
(virDomainSnapshotDefParseString): Use new convenience macros.

Often, we want to use XPath functions on the just-parsed document;
fold this into the parser function for convenience.

* src/util/xml.h (virXMLParseHelper): Add argument.
(virXMLParseStrHelper, virXMLParseFileHelper): Delete.
(virXMLParseCtxt, virXMLParseStringCtxt, virXMLParseFileCtxt): New
macros.
* src/libvirt_private.syms (xml.h): Remove deleted functions.
* src/util/xml.c (virXMLParseHelper): Add argument.
(virXMLParseStrHelper, virXMLParseFileHelper): Delete.

* cfg.mk (useless_free_options): Add xmlFreeDoc, xmlBufferFree.

Test failure exposed in commit 7d3390f8.

* tests/undefine: Fix to match updated test driver semantics.

* src/test/test_driver.c (testDomainUndefineFlags): Use right
variable name.

ACK was given too soon.  According to the code, the xm driver is
only used for inactive domains, and has no notion of an active
domain, thus, it cannot support undefine of a running domain.
The real fix for xen needs to be in the unified driver and/or
the xend level.

This reverts commit 49186ded.

Undefining a running domain will convert it to trasient, but keep
the domain still running.

* src/qemu/qemu_monitor_text.c: BALLOON_PREFIX was defined as
"balloon: actual=", which cause "actual=" is stripped early before
the real parsing. This patch changes BALLOON_PREFIX into "balloon: ",
and modifies related functions, also renames
"qemuMonitorParseExtraBalloonInfo" to "qemuMonitorParseBalloonInfo",
as after the changing, it parses all the info returned by "info balloon".

* .gnulib: Update to latest, for getcwd fixes.
* bootstrap: Resync to gnulib.

Although we are flushing cache after some critical writes (e.g.
volume creation), after some others we do not (e.g. volume cloning).
This patch fix this issue. That is for volume cloning, writing
header of logical volume, and storage wipe.

When spice_tls is set but listen_tls is not, we don't initialize
GnuTLS library. So any later gnutls call (e.g. during migration,
where we initialize a certificate) will access uninitialized GnuTLS
internal structs and throws an error.

Although, we might now initialize GnuTLS twice, it is safe according
to the documentation:

    This function can be called many times,
    but will only do something the first time.

This patch creates 2 functions: virNetTLSInit and virNetTLSDeinit
with respect to written above.

This patch adds the missing documentation about the scheduler parameter
"vcpu_period" and "vcpu_quota".

I did 'git add .' while in the middle of 'make syntax-check', and
it picked up a temporary file that should not be committed.

* .gitignore: Ignore sc_* from syntax check.

Regression introduced in commit 5d30db09.

* src/rpc/virnetsocket.c (virNetSocketNewListenUNIX) [WIN32]: Use
correct signature.

Regression introduced in commit b7e5ca48.

Mingw lacks kill(), but we were only using it for a sanity check;
so we can go with one less check.

Also, on OOM error, this function should outright fail rather than
claim that the pid file was successfully read.

* src/util/virpidfile.c (virPidFileReadPathIfAlive): Skip kill
call where unsupported, and report error on OOM.

If a client had initiated a stream abort, it will have a call
waiting for a reply in the queue. If more data continues to
arrive on the stream, the abort command could mistakenly get
signalled as complete. Remove the code from async data processing
that looked for waiting calls. Add a sanity check to ensure no
async call can ever be marked as needing a reply

* src/rpc/virnetclient.c: Ensure async data packets can't
  trigger a reply
