While doing migration on KVM host, found problem sometimes:
VM is already running on the target host and disappears from source
host, but 'virsh migrate' command line hangs, cannot exit normally.
If pressing "ENTER" key, it will exit.
The code hangs at tools/virsh-domain.c: cmdMigrate
->vshWatchJob->poll():
poll() is trying to select pipe_fd, which is used to receive message
from doMigrate thread. In debugging, found that doMigrate finishes
and at the end it does call safewrite() to write the retval ('0' or
'1') to pipe_fd, and the write is completed. But cmdMigrate poll()
cannot get the event. If pressing "ENTER" key, poll() can get the
event and select pipe_fd, then command line can exit.
In current code, authentication thread which is called by vshConnect
will use stdin, and at the same time, in cmdMigrate main process,
poll() is listening to stdin, that probably affect poll() to get
pipe_fd event. Better to move authentication before vshWatchJob. With
this change, above problem does not exist.

XM and XL config are very similar. Disks are specified differently
in XL, but the old XM disk config is still supported by XL. XL also
supports new config like spice that was never supported by XM.
This patch moves all the common parsing and formatting functions to
the new file xen_common.c and adapts the XM parser/formatter accordingly.
This restructuring paves way for introducing an XL parser/formatter in
the future.
While moving the code, fixup whitespace, comments, and style issues.

src/xenxs contains parsing/formating functions for the various xen
config formats, and is better named src/xenconfig.

Pin existing vcpus rather than existing vcpu pinning infos. This
increases the complexity of the lookup, but avoids pinning cpus that are
not enabled actually.
Remove the pinning info when removing to CPU, otherwise when the VM will
be started our code will try to pin non-existing vcpus as the definition
wasn't updated.

Tidy up control flow, change boolean argument to use 'bool', improve
error message in case the function is used to parse emulator pinning
info and avoid a few temp variables that made no sense.
Also when the function is called to parse emulator pinning info, there's
no need to check the processor ID in that case.
The check doesn't make much sense as right below it the entries are
either checked for duplicity or ignored in some cases. Having this check
doesn't actually forbid passing invalid values.
When editing guest's XML (on QEMU), it was possible to add multiple
listen elements into graphics parent element. However QEMU does not
support listening on multiple addresses. Configuration is tested for
multiple 'listen address' and if positive, an error is raised.

There are some stateless drivers which implement subdrivers
(typically vbox and its own network and storage subdrivers). However,
as of ba5f3c7c8e the vbox driver lives in the daemon, not the
client library. This means, in order for vbox (or any stateless domain
driver) to use its subdrivers, it must register before the general
drivers. Later, when the virConnectOpen function goes through the
subdrivers, stateless drivers are searched first. If the connection
request is aiming at stateless driver, it will be opened. Otherwise
the generic subdriver is opened.
The other change done in this commit is moving interface module load a
bit earlier to match the ordering in case libvirt is built without
driver modules.

Four functions are rewrite in this patch, that is:
vboxNodeGetInfo
vboxNodeGetCellsFreeMemory
vboxNodeGetFreeMemory
vboxNodeGetFreePages
Since these functions has nothing to do with vbox,
it can be directly moved to vbox_common.c. So, I
merged these things into one patch.
The vboxDomainSnapshotCreateXML integrated the snapshot redefine
with this patch:
http://www.redhat.com/archives/libvir-list/2014-May/msg00589.html
This patch introduced vboxSnapshotRedefine in vboxUniformedAPI to
enable the features.
This patch replace all version specified APIs to the uniformed api,
then, moving the whole implementation to vbox_common.c. As there
is only API level changes, the behavior of the function doesn't
change.
Some old version's defects has brought to the new one. The already
known things are:
*goto cleanup in a loop without releasing the pointers in the
loop.
*When function failed after machine unregister, no roll back
to recovery it and the virtual machine would disappear.
