8ff21f47f0 During WITHOUT ROWID table creation, if the sqlite3CreateTable() call fails 
due to an authorizer denying the INSERT into the sqlite_master table, then
detect this fact and abort the CREATE TABLE early, to avoid an assertion
fault.

19dc4d40e7 Identify specific FuncDef objects for window functions using the pointer to 
the function name (FuncDef.zName) rather than the pointer to the xStep method.
This allows xStep method pointer to be replaced with a single noopStepFunc()
procedure, and thus save having lots of different no-op step functions.
