[libvirt] [RFC: PATCH 2/2] viruri: add more tests



When qparams support was dropped in commit bc1ff160, we forgot
to add tests to ensure that viruri can do the same round trip
handling of a URI.

Also, we forgot to report an OOM error.

NOTE: THIS TEST CURRENTLY FAILS ON ANY QUERY WITH % ESCAPING.

* tests/viruritest.c (mymain): Add tests based on just-deleted
qparamtest.
(testURIParse): Allow difference in input and expected output.
* src/util/viruri.c (virURIFormat): Add missing error.
---

Right now, if uri->query contains escaping, such as one%20two,
virURIFormat mistakenly turns it into one%2520two.  But I'm not
sure how best to fix our code to allow proper round trips.

Therefore, I'm only posting this for review, but we have to fix
the bug before this can go into the tree.
