* Object Implementation Notes:
*
* Allocating a new object creates an object header and a block of
* uninitialized user data. A pointer to this uninitialized data is
* returned to the user. The structure looks as follows:
*
* +--------------------+
* | MAGIC HEADER |
* | (object header) |
* +--------------------+
* | user data | -- pointer returned from PKIX_PL_Object_Alloc
* +--------------------+
*
* Object operations receive a pointer to raw user data as an argument.
* The macro HEADER(object) returns a pointer to the object header.
* An assertion then verifies that the first field is the MAGIC_HEADER.
