If we're running qemu unprivileged, we need to chown any supplied kernel
or initrd before spawning it.

* src/qemu_driver.c: rename qemuDomainSetDiskOwnership() to
  qemuDomainSetFileOwnership(), pass it a path string instead of a disk
  definition and use it for chowning the kernel/initrd in
  qemuDomainSetAllDeviceOwnership()

While trying to remove uses of unsafe strncpy in the tree, I came
across a couple of usages in the ESX driver.  To my eyes, the snprintf
replacements do the same thing in less code, and are also safer.

* docs/logging.html[.in] try to include a little more description about
  the corner cases, things someone might get hung up on on.

* src/logging.c src/logging.h src/libvirt_private.syms:
  define new functions virLogSetFromEnv and virLogParseDefaultPriority
* qemud/qemud.c src/libvirt.c tests/eventtest.c: cleanup to use the
  unified functions

* tests/eventtest.c: don't covert high priority levels to debug level.
  Consider an invalid priority level setting a setup failure.

* qemud/qemud.c src/logging.[ch]: Similar as for general libvirt, don't
  convert high priority levels to debug level. Ignore LIBVIRT_LOG_FILTERS
  and LIBVIRT_LOG_OUTPUTS when they're set to the empty string, otherwise
  they can override a valid setting from the config file. Send all
  settings through the parser functions for validation, so that the
  existence of a bad setting doesn't nullify a good setting that should
  have applied -- particularly the default output. Keep the order of
  precedence consistent for all variables between the environment and
  the config file.  Warn when an invalid log level, filter, or output
  is ignored.
* src/libvirt_private.syms: export internally a few convenience functions

* src/libvirt.c src/logging.c: Don't convert high priority levels to the
  debug level. Don't parse LIBVIRT_LOG_FILTERS and LIBVIRT_LOG_OUTPUTS
  when they're set to the empty string. Warn when the user specifies an
  invalid value (empty string remains a noop).
* po/POTFILES.in: src/logging.c now include translatable strings

* src/esx/esx_driver.c src/esx/esx_util.[ch] src/esx/esx_vi.[ch]:
  just a name change

* src/esx/esx_driver.c: if esxOpen failed, priv->transport wasn't freed

* src/esx/esx_driver.c: catch an unchecked strdup in
  esxDomainGetOSType()

* configure.in NEWS docs/* libvirt.spec.in include/libvirt/libvirt.h:
  Release of 0.7.0
* po/*.po*: updated and regenerated the localization pool

* src/storage_backend.c: as the absence of units can be interpreted
  in diverging ways depending on the version

* src/lxc_driver.c: Check for name & UUID uniqueness when
  defining or creating domains

* src/lxc_driver.c: Remove transient VM after monitor triggered
  shutdown

* src/lxc_controller.c: Don't throw error in LXC startup if
  the cgroups driver mount isn't available. Improve error
  logging for resource setup

* configure.in: Don't set AM_CONDITIIONAL until *after* making
  the checks

* src/xm_internal.c: split the implementations of xenInotifyActive()

* docs/schemas/*.rng: the comments were wrong
* src/qemu_conf.c: typo in an error message

* src/xm_internal.c: in case of multiple connections to the xen driver
  and some clients were not using domain events, the whole /etc/xen
  monitoring would break leading to disapearing domains.

* src/xm_internal.c: bug when redefining a domain, if it was running
  we would loose its id

* src/xend_internal.c: extraneous ; in xenDaemonParseSxprGraphicsNew

* src/storage_conf.c src/internal.h: move previous check in internal.h
  and add a workaround for a GCC bug in Debian Etch on limit definitions

* configure.in: to activate Xen Inotify checking we need to check for
  sys/inotify.h availability

* configure.in: make it check by default for both

* configure.in: UML support requires sys/inotify.h so make it check
  by default.

* configure.in: if libcurl is not present ESX should be desactivated
  so default to check for esx

* src/esx/esx_driver.c src/esx/esx_vi.[ch] src/esx/esx_vmx.[ch]:
  adds version checking for GSX 2.0, allows to pass a specific port
  for the connection and also add a new specific gsx scheme for
  easier connections to GSX hosts

Fix  https://bugzilla.redhat.com/show_bug.cgi?id=479517

* src/buf.c: Cast to 'unsigned char' before doing compare to
  avoid rejecting 8-bit high characters

* src/openvz_driver.c: Remove unneccessary strdup() on hypervisor
  type api call

Fix up qemudDomainMigratePrepare2 to use virGetHostname instead of
gethostname.  Besides the fact that virGetHostname is far more clever,
there was a latent bug in the handling that could cause a buffer overflow
on a very long hostname.
