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

Bugfix for pageOrientedList.

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.

- 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.

Starting to rip the old jbhash implementation out, and replace it with a
...
linear hash implementation. In particular, I've implemented (sort of) an
iterator for linear hash, and (sort of) ported libdfa to linearhash.c
I say 'sort of' since this functionality is broken with this commit. On the other hand, CVS should build now, and the tests under lladd will pass. libdfa's new tests don't pass at the moment.

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...)

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.
