In an upcoming patch, I need the way to safely transfer a nested
virJSON object out of its parent container for independent use,
even after the parent is freed.
* src/util/virjson.h (virJSONValueObjectRemoveKey): New function.
(_virJSONObject, _virJSONArray): Use correct type.
* src/util/virjson.c (virJSONValueObjectRemoveKey): Implement it.
* src/libvirt_private.syms (virjson.h): Export it.
* tests/jsontest.c (mymain): Test it.

While investigating some memory leaks it was unclear whether the
JSON code correctly free'd all memory during parsing. Add a test
case which can be run under valgrind to clearly demonstrate that
the parser is leak free.
* tests/Makefile.am: Add 'jsontest'
* tests/jsontest.c: A few simple JSON parsing tests
