The added test case is the binary JSON equivalent of
{"a":{"š":null}}
with two modifications. First, the length of the string "š" has been corrupted
to 0xFFFFFF00. Second and more import, the Base::size field of the inner object
has been reset to 0.
On its own the first modification would normally trigger a validation error.
However, due to the second modification the Value::usedStorage for the inner
object evaluates to 0, completely disabling all further validation of the
object's contents.
Attempting to convert this binary JSON into standard JSON will lead to the JSON
writer trying to construct a QString of length 0xFFFFFF00.
Fixed by validating also objects with usedStorage == 0.

The added test case is a binary JSON file describing an array which contains
itself. This file passes validation even though attempting to convert it to
plain JSON leads to an infinite loop. Fixed by rejecting it in validation.

This method takes a pointer+size pair, but begins reading through the pointer
without first checking the size parameter. Fixed by checking the size parameter.
A new test case is added with an empty binary json file. Although the test does
not fail under normal conditions, the problem can be detected using valgrind or
AddressSanitizer.

This is in preparation to adding CBOR support. We don't need yet another
dir for CBOR and placing it in src/corelib/json is just wrong.
