Valgrind reported leaking of maxCpus and arch strings from
virXPathString, as well as the leak of the machineMaxCpus array.

Don't use 'str' for the strings we don't want to free, to allow
freeing of 'str' in the cleanup label and free machineMaxCpus
in virCapsReset too.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

As part of the goal to get away from doing string matching on
filenames when deciding whether to emit a log message, turn
the virLogSource enum into a struct which contains a log
"name". There will eventually be one virLogSource instance
statically declared per source file. To minimise churn in this
commit though, a single global instance is used.

The dtrace probe macros rely on the logging API. We can't make
the internal.h header include the virlog.h header though since
that'd be a circular include. Instead simply split the dtrace
probes into their own header file, since there's no compelling
reason for them to be in the main internal.h header.

We allow translation from no_bandwidth to has_bandwidth for a vnic.
However, going in the opposite direction is not implemented. It's not
limitation of the API rather than internal implementation. The problem
is, we correctly detect that user hasn't specified any outbound (say
he wants to clear out outbound). However, this gets overwritten by
current vnic outbound settings. Then, virNetDevBandwidthSet doesn't
change anything. We need to stop overwriting the outbound if users
don't want us to. Same applies for inbound.

If there should be some sort of separator it is better to use comment
with the filename, copyright, description, license information and

This patch is not trying to fix every switch, just the ones I worked
with last time, because some of these were especially unreadable.
Covers enums virDomainGraphicsType and virDomainChrType (where
applicable).

Also sort its cases by their value.

Commit a1cbe4b5 added a check for spaces around assignments and this
patch extends it to checks for spaces around '=='.  One exception is
virAssertCmpInt where comma after '==' is acceptable (since it is a
macro and '==' is its argument).

Coverity found an issue in lxc_driver and uml_driver that we don't
check the return value of register functions.

I've also updated all other places and unify the way we check the

Right now we are parsing the XML as though it's live, which for example
will choke on hardcoded XML like:

  <seclabel type='dynamic' model='selinux' relabel='yes'/>

Erroring with:

  $ sudo virsh domxml-to-native qemu-argv f
  error: XML error: security label is missing

All drivers are fixed, but only qemu was tested.

Just skip the vhost command line generation, since this won't work if
attempting to run manually.

-S causes qemu to start in the paused state. Since XML2Native is intended
to generate something that users can run directly, this will trip them up.

We have to explicitly destroy TAP devices on FreeBSD because
they're not freed after being closed, otherwise we end up with
orphaned TAP devices after destroying a domain.

This is also never seen by a human.

Many of the domain xml format functions (including all of the device
format functions) had hard-coded spaces, which made for incorrect
indentation when those functions were called in a different context
(for example, commit 2122cf39 added <interface> XML into the document
provided to a network hook script, and in this case it should have
been indented by 2 spaces, but was instead indented by 6 spaces).

To make it possible to insert a properly indented device anywhere into
an XML document, this patch removes hardcoded spaces from the
formatting functions, and calls virBufferAdjustIndent() at appropriate
places instead. (a regex search of domain_conf.c was done to assure
that all occurrences of hardcoded spaces were removed).

virDomainDiskSourceDefFormatInternal() is also called from
snapshot_conf.c, so two virBufferAdjustIndent() calls were temporarily
added around that call - those functions will have hardcoded spaces
removed in a separate patch.

This could cause some conflicts when backporting future changes to the
formatting functions to older branches, but fortunately the changes
are almost all trivial, so conflict resolution will be obvious.

When I played with virtlockd I was stunned by lacking
documentation. My frustration got bigger when I had to
read the patches to get the correct value to set in
qemu.conf.

Moreover, from pure libvirt-pride  I'm changing commented
value from sanlock to lockd. We want to favor our own
implementation after all.

The kernel didn't support the unprivileged SGIO for SCSI generic
device finally, and since it's unknow whether the way to support
unprivileged SGIO for SCSI generic device will be similar as for
SCSI block device or not, even it's simliar (I.e. via sysfs, for
SCSI block device, it's /sys/dev/block/8\:0/queue/unpriv_sgio,
for example), the file name might be different, So it's better not
guess what it should be like currently.

This patch removes the related code (mainly about the "shareable"
checking on the "sgio" setting, it's not supported at all, why
we leave checking code there? :-), and error out if "sgio" is
specified in the domain config.

Add VIR_DOMAIN_HOSTDEV_PCI_BACKEND_XEN. For legacy xen, it will use "pciback" as
stub driver.

Changes parameter from vm def to specific hostdevs info and name info, so that
it could be used more widely, e.g, could be used without full vm def info.

Some virHostdevXXXX methods included the string Hostdev again
as a suffix. Change the latter to Device instead.
