Suppress "chunk is not well balanced" errors from libxml2. libxml2 2.13 has an entirely different rule than earlier versions about when to emit "chunk is not well balanced" errors. This causes regression test output discrepancies for three test cases that formerly provoked that error (along with others) and now don't.
Closer inspection shows that at least in 2.13, this error is pretty useless because it can only be emitted after some other more-relevant error. So let's get rid of the cross-version discrepancy by just suppressing it. In case some older libxml2 version is capable of emitting this error by itself, suppress only when some other error has already been captured. Like 066e8ac6e and 6082b3d5d, this will need to be back-patched, but let's check the results in HEAD first. (The patch for xml_2.out, in particular, is blind since I can't test it here.)
