This format matches against null bytes, and prevents the test
expectation from being interpreted as binary data.
bless_tests.php will automatically replace \0 with %0 as well.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

When Wincache or APC are installed, the resource IDs are not the same.
This is because Wincache takes a few resource objects for itself. As a
result, these tests become false positives.
On Windows boxes, the microtime precision is not granular enough
to reliably register a difference if two calls to uniqid() are made
concurrently. This is a fix to the uniqid() test to avoid the false
positive when run on Windows machines. Also, added a test to exercise
the 'more_entropy' variant of uniqid().
