The linked list implementation now uses nested top actions. (Also, many bugfixes regarding nested top actions were introduced.)

Working, non-concurrent linear hash and linked list implementations.
The idea is to implement the non-concurrent versions, and then convert
them to concurrent versions using nested top actions.

Support for nested top actions, with simple unit test. (Haven't tested for thread safety yet.)

Preliminary version of logical logging linear hash. (No latching yet, and there are some bugs re-opening a closed hash.)

Implemented a linear hash from scratch. Concurrency hasn't been done, but it's probably correct in the single thread case.

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.

Fixed regressions, major update of page / slotted interfaces in anticipation of moving LLADD towards a generic transactional page system.

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.

bufferMananger is (really!) re-entrant now, performed big refactoring to prevent deadlocks, check_transactional2 ran overnight without coring, w/ 25 threads, and 10000 allocate/write/reads per thread. (The whole test suite was run in a loop...)
