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.)

libdfa ported to new hash table implementation. (Uses nested top actions.)

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 recover_split(), which is needed by the linear hash to recover properly from crashes. It hasn't been tested at all, and is not currently called by anything.

Lots of optimizations; re-did on-disk layout for the linear hash table.

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

Optimized the 'naive' linear hash table, and moved to sourceforge. :)

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