Daniel P. Berrangé	0279a51b83	tests: fix name of 32-bit x86 QEMU binary ... The 32-bit x86 binary is called qemu-system-i386, not qemu-system-i686. This mistake across many test XML files was not noticed because the mistake was also made in testutilsqemu.c when mocking the capabilities.

Eric Blake	1a4df34a0f	backup: Parse and output checkpoint XML ... Add a new file checkpoint_conf.c that performs the translation to and from new XML describing a checkpoint. The code shares a common base class with snapshots, since a checkpoint similarly represents the domain state at a moment in time. Add some basic testing of round trip XML handling through the new code. Of note - this code intentionally differs from snapshots in that XML schema validation is unconditional, rather than based on a public API flag. We have many existing interfaces that still need to add a flag for opt-in schema validation, but those interfaces have existing clients that may not have been producing strictly-compliant XML, or we may still uncover bugs where our RNG grammar is inconsistent with our code (where omitting the opt-in flag allows existing apps to keep working while waiting for an RNG patch). But since checkpoints are brand-new, it's easier to ensure the code matches the schema by always using the schema. If needed, a later patch could extend the API and add a flag to turn on to request schema validation, rather than having it forced (possibly just the validation of the <domain> sub-element during REDEFINE) - but if a user encounters XML that looks like it should be good but fails to validate with our RNG schema, they would either have to upgrade to a new libvirt that adds the new flag, or upgrade to a new libvirt that fixes the RNG schema, which implies adding such a flag won't help much. Also, the redefine flag requires the <domain> sub-element to be present, rather than catering to historical back-compat to older versions.

Eric Blake	d85842cfd7	backup: Document new XML for checkpoints ... Prepare for new checkpoint APIs by describing the XML that will represent a checkpoint. The checkpoint XML is modeled heavily after virDomainSnapshotPtr. See the docs for more details. Add testsuite coverage for some minimal uses of the XML (bare minimum, the sample from html, and a full dumpxml, and some counter-examples that should fail schema validation). Although use of the REDEFINE flag will require the <domain> subelement to be present, it is easier for most of the tests to provide counterpart output produced with the NO_DOMAIN flag (particularly since synthesizing a valid <domain> during testing is not trivial).
