Changed CLR log format so that it is identical to update entries. The old format pointed back to an earlier
...
entry in the log, complicating truncation significantly. The new format copies log entries into their CLRs,
and is somewhat redundant, as redo and undo information is stored in the CLR, but the undo information will
never be used...

only partially implemented.

Updates for 32-bit x86. There are still real 32-bit bugs being emitted as compiler warnings.

Needed to protect a linked list with a mutex. It's suprising that this hasn't come up before.

Factored logWriter.h out of the rest of the system. The only file that directly depends on it is logger2.c, which can
...
now dispatch requests to different (hardcoded) log implementations.

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

Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation.
...
Also, numerous bugfixes.

Refactored bufferMananger / pageCache, so that bufferMananger handles loading an unloading pages, and pageCache only implements the replacement policy.
...
Also, used memprof to detect and remove all memory leaks (at least all memory leaks that are encountered by check_transactional2), and fixed a number of misuses of the pblHash.

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...)

bufferMananger is *really* reentrant now! (I think) However, the same thread may not load a page more than once. So, LLADD has to be altered so that it never calls loadPage() more than once per operation (more efficient), and/or pin/unpin need to be implemented. An easy way to do pin/unpin is to have them pull things out of the cache replacement list, and then re-insert them.
