9e1ab1a8a4 Ensure that sqlite3_column_count() returns 0 for the "set" mode of "get/set" 
PRAGMA statements that do not return a value in that case (e.g. page_size,
cache_size, auto_vacuum).

957026ac78 Defer the bulk pcache1 memory allocation until the first page allocation 
request.  Limit the size of the pcache1 bulk allocation to the cache_size
setting.  Deallocate the bulk allocation on a sqlite3_db_release_memory()
request, if the bulk allocation is completely unused.
