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.

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.
