Portability fixes for FreeBSD and Mac OS. Check broke compatibility w/
...
old versions; added #ifdef so that both versions of check will work.

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...)

new benchmarks revealed that inserts for linkedList, pageOrientedList were taking O(n) time, yielding O(n^2)
...
time to build a list, since the lists could not contain duplicate keys. These operations are now O(1), and
the lists can contain duplicates.

Fixed up some return values; tests now pass with assert disabled.

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.

Added special 'EVERYTHING.script' which runs the tests from fastest to slowest. (To be run overnight...)

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.)
