Commit id's 'c8438010', '9bbf0d7e', and '2552fec24' altered the documentation
to describe adding a 'passphrase' type secret usage model in order to reference
the secret for a luks volume. After commit, it was deemed that a 'volume'
usage model should be used, so adjust the various documents in order rephrase
descriptions in order to follow the correct usage model.

In order to use more common code and set up for a future type, modify the
encryption secret to allow the "usage" attribute or the "uuid" attribute
to define the secret. The "usage" in the case of a volume secret would be
the path to the volume as dictated by the backwards compatibility brought
on by virStorageGenerateQcowEncryption where it set up the usage field as
the vol->target.path and didn't allow someone to provide it. This carries
into virSecretObjListFindByUsageLocked which takes the secret usage attribute
value from from the domain disk definition and compares it against the
usage type from the secret definition. Since none of the code dealing
with qcow/qcow2 encryption secrets uses usage for lookup, it's a mostly
cosmetic change. The real usage comes in a future path where the encryption
is expanded to be a luks volume and the secret will allow definition of
the usage field.
This code will make use of the virSecretLookup{Parse|Format}Secret common code.

The rule generating the HTML docs passing the --html flag
to xsltproc. This makes it use the legacy HTML parser, which
either ignores or tries to fix all sorts of broken XML tags.
There's no reason why we should be writing broken XML in
the first place, so removing --html and adding the XHTML
doctype to all files forces us to create good XML.
This adds the XHTML doc type and fixes many, many XML tag
problems it exposes.

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
