Fixed blob bug. The reason it's so slow is that it's logging a preimage + postimage of each blob and then synchronously writing to a second copy each time the blob is

Continued cleaning up allocation code. It seems really slow all of a sudden, so this commit probably introduced a performance bug.

Fixed behavior when __really_do_ralloc() is called, but the record's slot is greater than numslots_ptr().
...
Optimized slotted_compact and __really_do_ralloc() so that they try to put lower numbered slots earlier in the freelist.

Fixed freespace measurement during recovery/abort by adding slottedFreespaceForSlot()

The freespace calculations were double counting the new slot's header.

Numerous lock manager fixes; more realistic test case for lock manager, added support for optional page-level locking.(Still need to report deadlocks back up to the caller.)

page->dirty is now set correctly (assuming LSN's are updated properly). pageFile.c makes use of this fact by ignoring write requests on clean pages.

Fixed blob implementation (it was impossible to distinguish between a blob and a record of length 12), removed jbhash, and ported cht to linearHashNTA.

Re-implemented pageOrientedListNTA from scratch. It's now more flexible, but relies on features that are not provided by Talloc/Tdealloc, so performance isn't as good as it could be.

Implemented pages that store fixed sized records efficiently, and a java-style ArrayList data structure that efficiently supports (relatively) clustered, O(1) access time expandable arrays. (This will be used for the hash implementation...)

Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation.

Also, numerous bugfixes.

Implemented a freespace manager that should safely allocate space, even in the face of crashes, and can reclaim unused space (unless an application opens more than one simultaneous transaction that performs allocations)
...
Fixed some blob bugs (by adding extra fdatasync() calls).
Began factoring out the page management code so that it is an extenstion, and a less integral part of lladd.

Rewrote / refactored page.h. Now, it uses a freelist to reclaim slotid's within a page, and is implemented as two seperate modules. The first handles lsn's, and (will soon) check the type of each page, and then delegate work to a particular implementation of the second module.
