d0ea530b00 conf: Rename life cycle actions to event actions
While current on_{poweroff,reboot,crash} action configuration is about
configuring life cycle actions, they can all be considered events and
actions that need to be done on a particular event. Let's generalize the
code by renaming life cycle actions to event actions so that it can be
reused later for non-lifecycle events.

3af8280baf storage: Report UUID/name consistently in driver errors
Done with:

sed -i -e "s/no pool with matching uuid/no storage pool with matching uuid/g" src/storage/storage_driver.c
sed -i -e 's/"%s", _("no storage pool with matching uuid")/_("no storage pool with matching uuid %s"), obj->uuid/g' src/storage/storage_driver.c
sed -i -e 's/"%s", _("storage pool is not active")/_("storage pool '%s' is not active"), pool->def->name/g' src/storage/storage_driver.c

And a couple fixups before, during, and after, and a manual inspection
pass to make sure nothing was wonky.

4da9b2c163 Change qemuSetSchedularParameters to use AFFECT_CURRENT
When adding variants of parameter setting APIs which accepted
flags, the existing APIs were all adapted internally to pass
VIR_DOMAIN_AFFECT_CURRENT to the new API. The QEMU impl
qemuSetSchedularParameters was an exception, which instead
used VIR_DOMAIN_AFFECT_LIVE. Change this to match other
compatibility scenarios, so that calling

   virDomainSetSchedularParameters(dom, params, nparams);

Has the same semantics as

   virDomainSetSchedularParametersFlags(dom, params, nparams, 0);

And

   virDomainSetSchedularParametersFlags(dom, params, nparams, VIR_DOMAIN_AFFECT_CURRENT);

fcfa4bfb16 win32: Pretend that close-on-exec works
Currently virNetSocketNew fails because virSetCloseExec fails as there
is no proper implementation for it on Windows at the moment. Workaround
this by pretending that setting close-on-exec on the fd works. This can
be done because libvirt currently lacks the ability to create child
processes on Windows anyway. So there is no point in failing to set a
flag that isn't useful at the moment anyway.

844cdf22e6 qemu: Fix QMP detection of QXL graphics
With the recent introduction of QMP capabilities probing, libvirt failed
to detect support for QXL graphics in QEMU 1.2 and newer. In addition to
fixing that, this patch also causes libvirt to detect QXL support for
qemu-kvm-0.13.0, which doesn't advertise it in -help output but mentions
it in device list. Since qemu-kvm-0.13.0 supported -spice, it looks like
not having qxl in -help was a bug.

This patch updates virGetUserID and virGetGroupID to be able to parse a
user or group name in a similar way to coreutils' chown. This means that

name and if this fails they try to parse it as an ID.

returned by getpwnam_r and getgrnam_r.

5d692cc714 fix kvm_pv_eoi with kvmclock
When both kvmclock and kvm_pv_eoi are configured (either disabled or
enabled) libvirt will generate invalid CPU specification due to the
fact that even though kvmclock causes the CPU to be specified, it
doesn't set have_cpu flag to true (and the new kvm_pv_eoi as well).
This patch fixes the issue and adds a test exactly for that to show
that it is fixed correctly (and also to keep it that way in the future
of course).

283f1c4aef python: keep consistent handling of Python integer conversion
libvirt_ulonglongUnwrap requires the integer type of python obj.
But libvirt_longlongUnwrap still could handle python obj of
Pyfloat_type which causes the float value to be rounded up
to an integer.

For example
 >>> dom.setSchedulerParameters({'vcpu_quota': 0.88})
 0
libvirt_longlongUnwrap treats 0.88 as a valid value 0

However
 >>> dom.setSchedulerParameters({'cpu_shares': 1000.22})
libvirt_ulonglongUnwrap will throw out an error
"TypeError: an integer is required"

The patch make this consistent.

0821ea6b3c esx: Disable libcurl's use of signals to fix a segfault
libcurl uses a SIGALRM in combination with sigsetjmp/siglongjmp to be
able to abort a DNS lookup when it takes too long. The problem with this
in a multi-threaded application is that the signal handler for SIGALRM
and the call to siglongjmp can be executed on a thread that is different
from the one that initially did the SIGALRM setup and the call to
sigsetjmp. In the reported case this triggered a segfault.

Disable libcurl's use of signals to avoid this situation. This has the
disadvantage of losing the ability to abort synchronous DNS lookups which
might result in libcurl getting stuck in a DNS lookup in the worst case.
When libcurl was build with an asynchronous DNS backend such as c-ares
then there is no problem because the timeout mechanism works without
signals here anyway.

is obsoleted by util-linux-ng.  That is, on either platform, either

60469dd10f security: also parse user/group names instead of just IDs for DAC labels
The DAC driver is missing parsing of group and user names for DAC labels
and currently just parses uid and gid. This patch extends it to support
names, so the following security label definition is now valid:

  <seclabel type='static' model='dac' relabel='yes'>
      <label>qemu:qemu</label>
      <imagelabel>qemu:qemu</imagelabel>
  </seclabel>

When it tries to parse an owner or a group, it first tries to resolve it as
a name, if it fails or it's an invalid user/group name then it tries to
parse it as an UID or GID. A leading '+' can also be used for both owner and
group to force it to be parsed as IDs, so the following example is also
valid:

  <seclabel type='static' model='dac' relabel='yes'>
      <label>+101:+101</label>
      <imagelabel>+101:+101</imagelabel>
  </seclabel>

This ensures that UID 101 and GUI 101 will be used instead of an user or
group named "101".

c5f162200c build: avoid infinite autogen loop
Several people have reported that if the .gnulib submodule is dirty,
then 'make' will go into an infinite loop attempting to rerun bootstrap,
because that never cleans up the dirty submodule.  By default, we
should halt and make the user investigate, but if the user doesn't
know why or care that the submodule is dirty, I also added the ability
to 'make CLEAN_SUBMODULE=1' to get things going again.

Also, while testing this, I noticed that when a submodule update was
needed, 'make' would first run autoreconf, then bootstrap (which
reruns autoreconf); adding a strategic dependency allows for less work.

* .gnulib: Update to latest, for maint.mk improvements.
* cfg.mk (_autogen): Also hook maint.mk, to run before autoreconf.
