Init scripts removed pid file of the daemon. Removing pid files may be
harmful as new api for crash-safe pidfiles is used (introduced by
c8a3a265).

The function stop() was always returning 0 (OK) from killproc() even
in case of error.

/etc/sysconfig/libvirtd has a few environment variables for configuring
libvirt SDL audio. The libvirtd process doesn't see these, however, because
they are never exported. Let's export the variables after sourcing the
sysconfig script.

There is another problem here that the commented out values in the
sysconfig script are not neccessarily the actual defaults, we are qemus
mercy here. Not sure how to solve that.

Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=565238

- Avahi service is called 'avahi-daemon'
- chkconfig descriptions must use \ for line continuations

Noticed because virt-pki-validate was very inconsistent on
using tabs vs. 8 spaces, sometimes mixing both paradigms on
a single line.

'git diff -b' shows significant changes only in cfg.mk.

* cfg.mk (sc_TAB_in_indentation): Add a few files.
* daemon/libvirtd.init.in: Avoid tabs.
* tools/virt-pki-validate.in: Likewise.

https://bugzilla.redhat.com/show_bug.cgi?id=538701

* daemon/libvirtd.init.in: daemon/libvirtd.init.in were not mentionned
  in the usage message and if a missing or wrong argument is given it
  should return 2, not 1

From time to time I bork my install, and hate it when the initscript
returns no info. This patch removes the sanity check, which lets
the shell give us 'command not found' or 'permission denied' errors.

The libvirtd initscript could get confused between the system and
session instances of the daemon. To avoid this it is neccessary
to check the pidfile explicitly.

* daemon/libvirtd.init.in: Always check the pidfile of the system
  daemon to avoid confusion with the session daemons

* qemud/: Rename to daemon/
* Makefile.am, configure.in, src/Makefile.am, src/remote_internal.c,
  tests/Makefile.am, tests/eventtest.c: s/qemud/daemon/ where needed

* qemud/libvirtd.init.in: improve the LSB init header for the
  init.d file, patch by Frederik Himpe
Daniel

        * include/libvirt/libvirt.h.in, src/libvirt.c, src/driver.h,
          src/libvirt_sym.version: New virDomainMemoryPeek API.
        * qemud/remote.c, qemud/remote_protocol.x, src/remote_internal.c:
          Support for remote.
        * src/qemu_driver.c: QEMU driver implementation of API.
        * src/test.c: Test driver (null) implementation of API.
        * docs/hvsupport.html.in: Document API.
        * libvirt.spec.in: New path /var/cache/libvirt for temporary
          storage of memory images.
        * qemud/libvirtd.init.in: Remove any old temp files in
          /var/cache/libvirt on restarts.
        * src/Makefile.am: make install creates /var/cache/libvirt.
        * configure.in: Detect mkdir -p.

Fix typos and comments

* po/*: updated the localizations
* qemud/libvirtd.init.in: LSB'ization of the init script and
  couple of fixups
Daniel

        * qemud/libvirtd.in: synchronously restart the daemon in
        order to avoid https://bugzilla.redhat.com/238492

        * qemud/libvirtd.in: add init script for libvirt_qemud

        * qemud/Makefile.am: install it unless we were configured
        with --with-init-scripts=none

        * configure.in: add --with-init-scripts to allow us
        have different flavour init scripts
