Fixed numerous bugs in allocationPolicy.c and alloc.c
...
allocationPolicy.c was not handling deallocations correctly
Tdealloc() was not calling interpretRid() on its input before passing it into the allocationPolicy
Added locking support for TallocFromPage()

Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier
...
of pages, so it doesn't suggest ones that aren't already in the buffer pool unless it has to.
