Only in drivers which use virDomainObj, drivers that query hypervisor
for domain status need to be updated separately in case their hypervisor
supports this functionality.
The reason is also saved into domain state XML so if a domain is not
running (i.e., no state XML exists) the reason will be lost by libvirtd
restart. I think this is an acceptable limitation.
This has been present since the introduction of phypAttachDevice
in commit 444fd07a.
* src/phyp/phyp_driver.c (phypAttachDevice): Don't dereference
NULL.
virFDStreamClose used a mutex after it was freed, and failed
to destroy that mutex on its last use.
* src/fdstream.c (virFDStreamFree): Inline into sole caller...
(virFDStreamClose): ...to avoid use-after-free and leak.

Several vSphere API methods are called on global objects like the
FileManager, the PerformanceManager or the SearchIndex. The generator
input file allows to mark such methods and the generator generates
such method in a way that automatically handles marked parameter. This
is done by some special macros. Those were manually written and this
patch moves them to the generator.
One functionality change here is that we no longer force enable the event
timeout for every queued event, only enable it for the first event after
the queue has been flushed. This is how other drivers have already done it,
and I haven't encountered problems in practice.
v3:
Adjust for new virDomainEventStateNew argument
The same code for queueing, flushing, and deregistering events exists
in multiple drivers, which will soon use these common functions.
v2:
Adjust libvirt_private.syms
isDispatching bool fixes
NONNULL tagging
v3:
Add requireTimer parameter to virDomainEventStateNew
This structure will be used to unify lots of duplicated event handling code
across the state drivers.
v2:
Check for state == NULL in StateFree
Add NONNULL tagging
Use bool for isDispatching

Use capabilities to allow a driver to register a default <init> if none
is specified in the XML. Openvz was already open-coding this to be /sbin/init
LXC currently falls over if no init is specified, so an explicit error is
an improvement IMO.
(Side note: I don't think we can set a default value for LXC. If we use
/sbin/init but the user doesn't specify a separate root FS for their guest,
the container will rerun the host's init which can be traumatic :). For
virt-install I'm thinking of defaulting to /sbin/init if a root FS has
been specified, otherwise require the user to manually specify <init>)
This is needed if we want to transfer a temporary file. If the
transfer is done with iohelper, we might run into a race condition,
where we unlink() file before iohelper is executed.
* src/fdstream.c, src/fdstream.h,
src/util/iohelper.c: Add new option
* src/lxc/lxc_driver.c, src/qemu/qemu_driver.c,
src/storage/storage_driver.c, src/uml/uml_driver.c,
src/xen/xen_driver.c: Expand existing function calls
Add public API for taking screenshots of current domain console.
* include/libvirt/libvirt.h.in: add virDomainScreenshot
* src/libvirt_public.syms: Export new symbol
There is no need to redefine _GNU_SOURCE in tests that occur after
gl_INIT, since that macro already AC_DEFINE'd it for us.

This re-adds the example section originally written by Osier Yang,
and indicates the version in which the cputune parameters became
available in libvirt.

The public API and RPC over-the-wire format have no flags argument,
so neither should the internal callback API. This simplifies the
RPC generator.
* src/driver.h (virDrvNWFilterDefineXML): Drop argument that does
not match public API.
* src/nwfilter/nwfilter_driver.c (nwfilterDefine): Likewise.
* src/libvirt.c (virNWFilterDefineXML): Likewise.
* daemon/remote_generator.pl: Drop special case.
