It may happen that a developer wants to run just a specific
subset of tests:
tests $ VIR_TEST_RANGE=22 ../run ./virschematest
This now fails miserably:
==6840== Invalid read of size 8
==6840== at 0x4F397C0: virXMLValidatorValidate (virxml.c:1216)
==6840== by 0x402B72: testSchemaFile (virschematest.c:53)
==6840== by 0x403737: virTestRun (testutils.c:180)

==6840== by 0x4035A9: main (virschematest.c:217)
==6840== Address 0x10 is not stack'd, malloc'd or (recently) free'd
Problem is, we are trying to do two types of tests here: validate
RNG schema itself, and validate XML files against RNG schemas.
And the latter tries to re-use a resource allocated in the
former. Therefore if the former is skipped (due to
VIR_TEST_RANGE) we have to allocate the resource manually.

Failure to parse the schema file would not trigger a test suite failure.
In addition to making the test fail it's necessary to split up the
parsing of the schema file into a separate test.
This is necessary as the XML validator uses libvirt errors to report
problems parsing of the actual schema RNG needs to be split out into a
separate function and called via virTestRun which has the
infrastructure to report them.
This way we can safely differentiate what XMLs contain whole domain
definitions and which contain just devices. Thanks to that we can
test the domain XMLs in virschematest again.

So the story goes like this. The testSchemaDirs() function is
called with: a) the schema file, b) list of the directories that
contains XMLs documents that should be checked against the schema
file from a). However, the directories in the list are really
just their names and it's up to testSchemaDirs to construct the
absolute path and call testSchemaDir() which then does the actual
validation. The absolute path is constructed, but never actually
used (maybe due to a typo). Thus a VPATH build is broken.
