60625313b0 Increase the default SQLITE_MAX_SCHEMA_RETRY to 50. Make sure that macro 
covers every case where a prepared statement might need to be reprepared due
to a schema change.  The sqlite3_exec() interface now uses 
sqlite3_prepare_v2().

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)
