633e6d57d9 Implement the "lookaside" memory allocation cache. Use of this cache makes 
the speed1.test script run about 15% faster.  Added new interfaces to
control the cache. (CVS 5488)

c702c7ccdd Use the actual size of memory allocations to update the memory status 
counters.  Fix the roundup() function of mem3 to be much closer to the
actual allocation size.  Ticket #3226. (CVS 5440)

f089aa459e Completely rework the sqlite3SetString() primitive so that it honors the

4b9507a0f1 Fix a problem in the test suite that could cause a crash if using a pre-allocated block of memory for pages (the problem was that sqlite3_shutdown() was being called while there were still open database connections). (CVS 5259)

f714199054 Add some test logic to the new memory allocation subsystem. (Lots more needed.) 
The test suite is currently indicating memory leaks, though it is unclear if
this is a true code problem or just an instrumentation problem. (CVS 5240)
