- Introduce php_open_temporary_file(), in place of tempnam(). Still
needs testing under UNIX (mkstemp()), works reliably under Windows now.
- Reimplement the mechanism for unlinking uploaded files at the end of the request
(was it ever tested?). Files moved with move_uploaded_file() will not be unlink()'d
again, to avoid (albeit very unlikely) race conditions.

Changed lots of PHP 3 licence headers to PHP 4, mainly in .h files.
Added a few RCS $Id$ tags.

# Note: I have avoided changing any .h files if the corresponding .c file
# had not already been changed as I am not sure if there are any legal
# issues here. So some extensions still have PHP 3 headers.

Change the serialization semantics to:

* if a certain object is of class INCOMPLETE_CLASS, the serializer will
lookup the previously stored original class name of that object, and
use that class name to serialize the object.

Change the deserialization semantics to:

* if the class of an object, which is to be instantiated, is not found
in the current context, the class name will be stored for later
retrieval, and the class of that object is changed to INCOMPLETE_CLASS.

All function calls, property gets, and property sets operating on an
object of class INCOMPLETE_CLASS cause the execution to halt and to
output an informative error message.
