Implement gdi pool. An allocator for user mode gdi object attributes. The old method allocated a 4k page for every object, wasting 4k physical memory and 64k address space (allcoation granularity) The new allocator creates a per process pool for each object attribute type. Allocations are done from "sections" that start with 1 page and grow dynamically up to 64k, if neccessary a new section is allocated. This will use about 1/10 of memory for dc attributes and 1/512 for brush attributes. Also allocation is way faster. Caching object attributes is not neccessary anymore. svn path=/trunk/; revision=51357
