regions now make use of nested top actions, so they're almost correct. (Still need to lock freed regions until end of transaction.)

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

More steps toward factoring page allocation out of record allocation.

Preliminary benchmark program uploads for SEDA-style response time percentiles vs requests / second
...
Also added a few cute little utilities:
- truncate_log
- run_recovery
Upped max # of concurrent transactions. (Current throughput during benchmarking remains ~flat up to 32,000
threads, but past max concurrent transactions was 1,000...)

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

- linkedListNTA is now re-entrant.
...
- linearHashNTA now uses nested top actions, is re-entrant, and supports a
non-re-entrant iterator
- 'recursive' nested top actions allow nested top actions to be nested within each
other.

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.

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.

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.
