Consider using 'out' instead of 'ref' for methods that only return values. #125

Consider using 'out' instead of 'ref' for methods that only return values to 
avoid misleading compiller error:

Use of unassigned local variable '...'.

For example methods:

sqlite3_open
sqlite3_prepare_v2

can be declared as 

public static int sqlite3_open(string zFilename, out sqlite3 ppDb);
public static int sqlite3_prepare_v2(sqlite3 db, string zSql, int nBytes, out 
sqlite3_stmt ppStmt, ref string pzTail);

without canges in logic. And with a little bit of change to:

public static int sqlite3_open(string zFilename, out sqlite3 ppDb);
public static int sqlite3_prepare_v2(sqlite3 db, string zSql, int nBytes, out 
sqlite3_stmt ppStmt, out string pzTail);
