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)

99e925da51 Fix a problem with the incremental blob API. sqlite3_blob_open() was always reading the data for the leftmost column of the row that the opened blob was stored in. If this column happened to contain a (the) large blob, sqlite would make a large memory allocation to read the data into. Which defeats the purpose of using incremental blobs. (CVS 5222)
