required to the code you end up with either distractingly broken

If you use the VDDK library to access virtual machines remotely, you
really need to know the Managed Object Reference ("moref") of the VM.
This must be passed each time you connect to the API.

For example nbdkit's VDDK plugin requires a moref to be passed to
mount up a VM's disk remotely:

 nbdkit vddk user=root password=+/tmp/rootpw \
             server=esxi.example.com thumbprint=xx:xx:xx:... \
             vm=moref=2 \
             file="[datastore1] Fedora/Fedora.vmdk"

Getting the moref is a huge pain.  To get some idea of what it is, why
it is needed, and how much trouble it is to get it, see:
https://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-1-overview.html
https://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-2-technical.html

However the moref is available conveniently in the internals of the
libvirt VMX driver.  This patch exposes it as a custom XML element
using the same "vmware:" namespace which was previously used for the
datacenterpath (see libvirt commit 636a9905).

It appears in the XML like this:

<domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
  <name>Fedora</name>
...
  <vmware:datacenterpath>ha-datacenter</vmware:datacenterpath>
  <vmware:moref>2</vmware:moref>
</domain>

Note that the moref can appear as either a simple ID (for esx://
connections) or as a "vm-<ID>" (for vpx:// connections).  It should be
treated by users as an opaque string.

Variable def going out of scope leaks the storage def.source.hosts points to.

Use MD5_DIGEST_SIZE or VIR_UUID_BUFLEN rather than VIR_UUID_STRING_BUFLEN
when compare @uuid with @md5.

So far our code is full of the following pattern:

  dom = virGetDomain(conn, name, uuid)
  if (dom)
      dom->id = 42;

There is no reasong why it couldn't be just:

  dom = virGetDomain(conn, name, uuid, id);

After all, client domain representation consists of tuple (name,
uuid, id).

When fetching domains with virConnectListAllDomains() and when filtering
by snapshot existence is requested the ESX driver first lists all the
domains and then check one-by-one for snapshot existence. This process
takes unnecessarily long time.

To significantly improve the time necessary to finish the query we can
request the snapshot related info directly when querying the list of
domains from VMware.

I'm tired of mistyping this all the time, so let's do it the same all
the time (similar to how we changed all "Pci" to "PCI" awhile back).

(NB: I've left alone some things in the esx and vbox drivers because
I'm unable to compile them and they weren't obviously *not* a part of
some API. I also didn't change a couple of variables named,
e.g. "somethingIptables", because they were derived from the name of
the "iptables" command)

The virConnectOpenInternal method opens the libvirt client
config file and uses it to resolve things like URI aliases.

There may be driver specific things that are useful to
store in the config file too, so rather than have them
re-parse the same file, pass the virConfPtr down to the
drivers.

Make it obvious that the flag is controlling RNG schema validation.

So the idea is as follows: firstly we obtain a list of all the
luns, then iterate over it trying to find the one we want to work
with and after all the iterations we detect whether we have found
something. Now, the last check is broken, because it compares a
value form previous iteration, not the one we've just been
through.

Then, when computing md5 sum of lun's UUID, we use wrong variable
again. Well, @hostScsiDisk which is type of esxVI_HostScsiDisk
extends esxVI_ScsiLun type so they both have the uuid member, but
it just doesn't feel right to access the data via two different
variables in one function call.

This patch fixes an issue where screenshot API call was failing when
the esx/vcenter password contains special characters such as
apostrophee. The reason for failures was that passwords were escaped
for XML and stored in esxVI_Context which was then passed to raw CURL
API calls where the password must be passed in original form to
authenticate successfully. So this patch addresses this by storing
original passwords in the esxVI_Context struct and escape only for
esxVI_Login call.

This is because there's a known issue where ESX will refuse to attach
drives bigger than 4TB when virtualHW < 9. Therefore, to avoid that
use the higher virtualHW for hosts that support it.
