Add an impl of +virGetUserRuntimeDirectory, virGetUserCacheDirectory
virGetUserConfigDirectory and virGetUserDirectory for Win32 platform.
Also create stubs for non-Win32 platforms which lack getpwuid_r()

In adding these two helpers were added virFileIsAbsPath and
virFileSkipRoot, along with some macros VIR_FILE_DIR_SEPARATOR,
VIR_FILE_DIR_SEPARATOR_S, VIR_FILE_IS_DIR_SEPARATOR,
VIR_FILE_PATH_SEPARATOR, VIR_FILE_PATH_SEPARATOR_S

All this code was adapted from GLib2 under terms of LGPLv2+ license.

Libtool supports linking directly against .o files on some platforms
(such as Linux), which happens to be the only place where we are
actually doing that (for the dtrace-generated probes.o files).  However,
it raises a big stink about the non-portability, even though we don't
attempt it on platforms where it would actually fail:

  CCLD   libvirt_driver_qemu.la

*** Warning: Linking the shared library libvirt_driver_qemu.la against
the non-libtool
*** objects  libvirt_qemu_probes.o is not portable!

This shuts libtool up by creating a proper .lo file that matches
what libtool normally expects.

If vdsm is installed and configured in Fedora 17, we add the following

When building as driver modules, it is not possible for the QEMU
driver module to reference the DTrace/SystemTAP probes linked into
the main libvirt.so. Thus we need to move the QEMU probes into a
separate file 'libvirt_qemu_probes.d'. Also rename the existing
file from 'probes.d' to 'libvirt_probes.d' while we're at it

Since we have drivers which depend on each other (ie QEMU/LXC
depend on the network driver APIs), we need to use RTLD_GLOBAL
instead of RTLD_LOCAL. While this pollutes the calling binary
with many more symbols, this is no worse than if we directly
link to the drivers, and this only applies to libvirtd

The libvirt_test.la library was introduced to allow test suites
to reference internal-only symbols. These days, nearly every
symbol we care about is in src/libvirt_private.syms, so there
is no need for libvirt_test.la to continue to exist

* src/Makefile.am: Delete libvirt_test.la & add new .syms files
* src/libvirt_private.syms: Export symbols needed by test suite
* tests/Makefile.am: Link to libvirt_test.la. Ensure LXC tests link
  to network_driver.la
* src/libvirt_esx.syms, src/libvirt_openvz.syms: Add exports needed
  by test suite

libvirt_driver_nodedev.la should not link against either
libvirt_util.la or gnulib.la, since libvirt.so brings
in those deps.

The driver modules all use symbols which are defined in libvirt.so.
Thus for loading of modules to work, the binary that libvirt.so
is linked to must export its symbols back to modules. If the
libvirt.so itself is dlopen()d then the RTLD_GLOBAL flag must
be set. Unfortunately few, if any, programming languages use
the RTLD_GLOBAL flag when loading modules :-( This means is it
not practical to use driver modules for any libvirt client side
drivers (OpenVZ, VMWare, Hyper-V, Remote client, test).

This patch changes the build process so only server side drivers
are built as modules (Xen, QEMU, LXC, UML)

* daemon/libvirtd.c: Add missing load of 'interface' driver
* src/Makefile.am: Only build server side drivers as modules
* src/libvirt.c: Don't load any driver modules

The libvirt-lock-sanlock RPM requires libvirtd, so its RPM dep
should be on libvirt-daemon, not libvirt

and use it for virDomainParseMemory. This allows to parse arbitrary
scaled value, not only memory related values as needed for the

This reverts commit b1e374a7, which was
rather bad since I failed to consider all sides of the issue. The main
things I didn't consider properly are:

- a thread which sends a non-blocking call waits for the thread with
  the buck to process the call
- the code doesn't expect non-blocking calls to remain in the queue
  unless they were already partially sent

Thus, the reverted patch actually breaks more than what it fixes and
clients (which may even be libvirtd during p2p migrations) will likely
end up in a deadlock.

The pciDevice structure corresponding to the device being hot-unplugged
was freed after it was "stolen" from activeList. The pointer was still
used for eg-inactive list. This patch removes the free of the structure
and frees it only if reset fails on the device.

This was forgotten in commit cdb87b1c.

I'm tired of writing:

bool sep = false;
while (...) {
    if (sep)
       virBufferAddChar(buf, ',');
    sep = true;
    virBufferAdd(buf, str);
}

This makes it easier, allowing one to write:

while (...)
    virBufferAsprintf(buf, "%s,", str);
virBufferTrim(buf, ",", -1);

to trim any remaining comma.

* src/util/buf.h (virBufferTrim): Declare.
* src/util/buf.c (virBufferTrim): New function.
* tests/virbuftest.c (testBufTrim): Test it.

This patch adds support for a new storage backend with RBD support.

RBD is the RADOS Block Device and is part of the Ceph distributed storage
system.

It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.

To function this backend relies on librbd and librados being present on the
local system.

The backend also supports Cephx authentication for safe authentication with
the Ceph cluster.

For storing credentials it uses the built-in secret mechanism of libvirt.
