This will eventually replace virQEMUBuildBufferEscapeComma, however
it's not possible right now. Some parts of the code that uses the
old function needs to be refactored.

Almost none of our virJSONValue*Get* functions accept const virJSONValue
pointers and it wouldn't even make sense since we sometimes modify what
we get. And because there is no reason for preventing callers of
virJSONValueObjectForeachKeyValue from modifying the values they get in
each iteration we can just stop doing it.

To allow richer definitions of disk sources add infrastructure that will
allow to register functionst generating a JSON object based definition.
This infrastructure will then convert the definition to the proper
command line syntax and use it in cases where it's necessary. This will
allow to keep legacy definitions for back-compat when possible and use
the new definitions for the configurations requiring them.
Add support for converting objects nested in arrays with a numbering
discriminator on the command line. This syntax is used for the
object-based specification of disk source properties.
For use with memory hotplug virQEMUBuildCommandLineJSONRecurse attempted
to format JSON arrays as bitmap on the command line. Make the formatter
function configurable so that it can be reused with different syntaxes
of arrays such as numbered arrays for use with disk sources.
This patch extracts the code and adds a parameter for the function that
will allow to plug in different formatters.
Refactor the command line generator by adding a wrapper (with
documentation) that will handle the outermost object iteration.
This patch also renames the functions and tweaks the error message for
nested arrays to be more universal.
The new function is then reused to simplify qemucommandutiltest.

If the volume xml was looking to create a luks volume take the necessary
steps in order to make that happen.
The processing will be:
1. create a temporary file (virStorageBackendCreateQemuImgSecretPath)
1a. use the storage driver state dir path that uses the pool and
volume name as a base.
2. create a secret object (virStorageBackendCreateQemuImgSecretObject)
2a. use an alias combinding the volume name and "_luks0"
2b. add the file to the object
3. create/add luks options to the commandline (virQEMUBuildLuksOpts)
3a. at the very least a "key-secret=%s" using the secret object alias
3b. if found in the XML the various "cipher" and "ivgen" options

Move the module from qemu_command.c to a new module virqemu.c and
rename the API to virQEMUBuildObjectCommandline.
This API will then be shareable with qemu-img and the need to build
a security object for luks support.
