Preparation for offload of allocations from device's memory
to separate thread. Procedure PutBytesAlign is called to
allocate memory chunk from device memory and copy data to it.
With current commit the procedure (if called with non-NULL
linked list root entry parameter) can use non-forced allocation.
If such allocation fails, it allocates 'delayed' chunk from
OS memory and copies data to it. Later before sending drawable command
this chunk shall be processed, storage allocated from device memory
(forced) and data copied to it.
