This series fixes 'virsh snapshot-dumpxml' to use nicer formatting.
Patch 1 adds some nice helper routines, patches 2-13 are mostly
mechanical conversions to use the helpers and pass indentation
levels through the entire call chain, and patch 14 adds a test
which uncovered a couple minor issues in how formatting was done.
Hi, I applied these patches and tested it a little bit.
I created a snapshot of a running vm, before applying these patches,
snapshot-dumpxml the snapshot output:

It can be seen that <domain></domain> didn't incident well, it's in the
same level with the domainsnapshot.
After applying these patches making, restarting the libvirtd, then virsh
snapshotdumpxml the snapshot output:
<domainsnapshot>
<name>firstshot</name>
<state>running</state>

It can be seen that the <domain></domain> indent correctly.
I typed 'make check' in the tests directory. The
domainsnapshotxml2xmltest part output:
TEST: domainsnapshotxml2xmltest
...... 6 OK
PASS: domainsnapshotxml2xmltest
I ran the domainsnapshotxml2xmltest script, it output:
TEST: domainsnapshotxml2xmltest
...... 6 OK
That's what I've done. Thanks.
