Add volume encryption information handling. Define an <encryption> tag specifying volume encryption format and format-depenedent parameters (e.g. passphrase, cipher name, key length, key). Currently the only defined parameter is a reference to a "secret" (passphrase/key) managed using the virSecret* API. Only the qcow/qcow2 encryption format, and a "default" format used to let libvirt choose the format during volume creation, is currently supported. This patch does not add any users; the <encryption> tag is added in the following patches to both volumes (to support encrypted volume creation) and domains. * docs/*.html: Re-generate * docs/formatstorageencryption.html.in, docs/sitemap.html.in: Add page describing storage encryption data format * docs/schemas/Makefile.am, docs/schemas/storageencryption.rng: Add RNG schema for storage encryption format * po/POTFILES.in: Add src/storage_encryption_conf.c * src/libvirt_private.syms: Export virStorageEncryption* functions * src/storage_encryption_conf.h, src/storage_encryption_conf.c: Internal helper APIs for dealing with storage encryption format * libvirt.spec.in, mingw32-libvirt.spec.in: Add storageencryption.rng RNG schema

<h2>
<a name="SecretAttributes" id="SecretAttributes">Secret XML</a>
</h2>
<p>
Secrets stored by libvirt may have attributes associated with them, using
the <code>secret</code> element. The <code>secret</code> element has two
optional attributes, each with values '<code>yes</code>' and
'<code>no</code>', and defaulting to '<code>no</code>':
</p>
<dl><dt><code>ephemeral</code></dt><dd>This secret must only be kept in memory, never stored persistently.
</dd><dt><code>private</code></dt><dd>The value of the secret must not be revealed to any caller of libvirt,
nor to any other node.
</dd></dl>
<p>
The top-level <code>secret</code> element may contain the following
elements:
</p>
<dl><dt><code>uuid</code></dt><dd>
An unique identifier for this secret (not necessarily in the UUID
format). If omitted when defining a new secret, a random UUID is
generated.
</dd><dt><code>volume</code></dt><dd>Key of a volume this secret is associated with. It is safe to delete
the secret after the volume is deleted.
</dd><dt><code>description</code></dt><dd>A human-readable description of the purpose of the secret.
</dd></dl>
