strcase{cmp/str} have the drawback of being sensitive to the global
locale; this is unacceptable in a library setting.  Prefer a
hard-coded C locale alternative for all but virsh, which is user
facing and where the global locale isn't changing externally.

In qemu-0.12.* "device '...' is locked" message was changed to "Device
..." so libvirt was no longer detecting this as an error.

Fix this which went into documentation

If qemu quited unexpectedly when we call qemuMonitorJSONHMP(),
libvirt will crash.
Steps to reproduce this bug:
1. use gdb to attach libvirtd, and set a breakpoint in the function
   qemuMonitorSetCapabilities()
2. start a vm
3. let the libvirtd to run until qemuMonitorJSONSetCapabilities() returns.
4. kill the qemu process
5. continue running libvirtd

If the monitor met a error, and we will call qemuProcessHandleMonitorEOF().
But we may try to send monitor command after qemuProcessHandleMonitorEOF()
returned. Then libvirtd will be blocked in qemuMonitorSend().

Steps to reproduce this bug:
1. use gdb to attach libvirtd, and set a breakpoint in the function
   qemuConnectMonitor()
2. start a vm
3. let the libvirtd to run until qemuMonitorOpen() returns.
4. kill the qemu process
5. continue running libvirtd

qemuDriverUnlock() wasn't called on 2 exit paths
* src/qemu/qemu_driver.c: fix qemudDomainSave() to always unlock
  the driver before exiting on error

Currently libvirt's default logging is limited and it is difficult to
determine what was happening when a proglem occurred (especially on a
machines where one don't know the detail.)  This patch helps to do that
by making additional logging available for the following events:

  creating/defining/undefining domains
  creating/defining/undefining/starting/stopping networks
  creating/defining/undefining/starting/stopping storage pools
  creating/defining/undefining/starting/stopping storage volumes.

* AUTHORS: add Naoya Horiguchi
* src/network/bridge_driver.c src/qemu/qemu_driver.c
  src/storage/storage_driver.c: provide more VIR_INFO logging

The new iohelper binary was missing from the packaging spec

v1 - v2:
  * Add missed tests/qemuxml2argvdata/qemuxml2argv-cputune.args

Not sure if it's the correct way to add cputune xml for xend driver,
and besides, seems "xm driver" and "xen hypervisor" also support
vcpu affinity, do we need to add support for them too?

LXC driver doesn't support vcpu affinity yet, so just need
to modify it to support cpu shares.

When domain startup, setting cpu affinity and cpu shares according
to the cputune xml specified in domain xml.

Modify "qemudDomainPinVcpu" to update domain config for vcpupin,
and modify "qemuSetSchedulerParameters" to update domain config
for cpu shares.

v1 - v2:
   * Use "VIR_ALLOC_N" instead of "VIR_ALLOC_VAR"
   * But keep raising error when it fails on adding vcpupin xml
     entry, as I still don't have a better idea yet.

Implementations of following functions:
  virDomainVcpupinIsDuplicate
  virDomainVcpupinFindByVcpu
  virDomainVcpupinAdd

Update "virDomainDefParseXML" to parse, and "virDomainDefFormatXML"
to build cputune xml, also implementations of new internal helper
functions.

v1 - v2:
  * Resolve potential crash bug of "virDomainVcpupinAdd"

Also related new functions' declaration, and expose the new introduced
functions in libvirt_private.syms.

v1 - v2:
  Don't expose "virAllocVar" in libvirt_private.syms

v1 - v3:
  * More clear document for "cpu shares", adopted suggestions from
    Matthias Bottle and Daniel Veillard.

v1 - v2:
  * Remove upper limit of cpu shares. (Suggested by Matthias Bottle)

My earlier testing for commit 34fa0de0 was done while starting
just-built libvirt from an unconfined_t shell, where the fds happened
to work when transferring to qemu.  But when installed and run under
virtd_t, failure to label the raw file (with no compression) or the
pipe (with compression) triggers SELinux failures when passing fds
over SCM_RIGHTS to svirt_t qemu.

* src/qemu/qemu_migration.c (qemuMigrationToFile): When passing
FDs, make sure they are labeled.

First fallout of fd: migration - it looks like SELinux enforcing
_does_ require fd labeling (running uninstalled libvirtd from an
unconstrained shell had no problems, but once faked out by doing
 chcon `stat -c %C /usr/sbin/libvirtd` daemon/libvirtd
 run_init $PWD/daemon/libvirtd
to run it with the same context as an init script service, and with
SELinux enforcing, I got a rather confusing failure:
error: Failed to save domain fedora_12 to fed12.img
error: internal error unable to send TAP file handle: No file descriptor supplied via SCM_RIGHTS

This fixes the error message, then I need to figure out a subsequent
patch that does the fsetfilecon() necessary to keep things happy.
It also appears that libvirtd hangs on a failed fd transfer; I don't
know if that needs an independent fix.

* src/qemu/qemu_monitor_text.c (qemuMonitorTextSendFileHandle):
Improve message, since TAP is no longer only client.

* .gitignore: Exclude libvirt_iohelper.

  libxlDomainXMLToNative

Hook the virtual cpu functions to their libxenlight counterparts

* src/libxl/libxl_driver.c: implements libxlDomainSetVcpus,
  libxlDomainGetVcpus, libxlDomainSetVcpusFlags,
  libxlDomainGetVcpusFlags and libxlDomainPinVcpu

  points for event(de)register(any)

* src/libxl/libxl_driver.c: use ignore_value() in libxlDomainObjUnref
  and libxlCreateDomEvents

The daemon loops over the linked list of streams when a client
quits, closing any that the client hadn't already closed. Except
it didn't ever move to the next element in the list!

* daemon/stream.c: Fix loop over linked list of streams

* daemon/remote.c, src/remote/remote_driver.c: Implementation
  of storage vol upload/download APIs
* src/remote/remote_protocol.x: Wire protocol definition for

Use generic FD streams to allow data upload/download to/from
any storage volume

* src/storage/storage_driver.c: Wire up upload/download APIs

The new commands vol-upload and vol-download, allow a local file
to be transferred to/from a storage volume.

* tools/virsh.c: Add vol-upload and vol-download commands
* tools/virsh.pod: Document new commands

New APIs are added allowing streaming of content to/from
storage volumes.

* include/libvirt/libvirt.h.in: Add virStorageVolUpload and
  virStorageVolDownload APIs
* src/driver.h, src/libvirt.c, src/libvirt_public.syms: Stub
  code for new APIs
* src/storage/storage_driver.c, src/esx/esx_storage_driver.c:
  Add dummy entries in driver table for new APIs

The O_NONBLOCK flag doesn't work as desired on plain files
or block devices. Introduce an I/O helper program that does
the blocking I/O operations, communicating over a pipe that
can support O_NONBLOCK

* src/fdstream.c, src/fdstream.h: Add non-blocking I/O
  on plain files/block devices
* src/Makefile.am, src/util/iohelper.c: I/O helper program
* src/qemu/qemu_driver.c, src/lxc/lxc_driver.c,
  src/uml/uml_driver.c, src/xen/xen_driver.c: Update for
  streams API change

The example C event loop code is a nasty hack and not compliant
with the require API semantics. Delete this, so that developers
don't mistakenly copy it. Instead call the new public event loop
APIs.

Update the python event loop example, so that it can optionally
use the public event APIs, as an alternative to the pure python
code. The pure python event code is a good working example, so
don't delete it.

Also make the python example use a read only connection to avoid
authentication prompts

* examples/domain-events/events-c/event-test.c: Replace event
  loop code with use of public APIs
* examples/domain-events/events-python/event-test.py: Allow
  optional use of new public event APIs

Regression introduced in commit 6034ddd5.

* src/qemu/qemu_driver.c (qemudDomainSaveFlag): Jump to correct
label.

* src/util/command.c (virCommandAbort) [WIN32]: Provide stub.
Reported by Daniel P. Berrange's autobuilder.

Spawn the compressor ourselves, instead of requiring the shell.

* src/qemu/qemu_migration.c (qemuMigrationToFile): Spawn
compression helper process when needed.

SELinux labeling and cgroup ACLs aren't required if we hand a
pre-opened fd to qemu.  All the more reason to love fd: migration.

* src/qemu/qemu_migration.c (qemuMigrationToFile): Skip steps
that are irrelevant in fd migration.

This points out that core dumps (still) don't work for root-squash
NFS, since the fd is not opened correctly.  This patch should not
introduce any functionality change, it is just a refactoring to
avoid duplicated code.

* src/qemu/qemu_migration.h (qemuMigrationToFile): New prototype.
* src/qemu/qemu_migration.c (qemuMigrationToFile): New function.
* src/qemu/qemu_driver.c (qemudDomainSaveFlag, doCoreDump): Use
it.
