flaws list)
TODO: 
 * verify that no sequence of API calls produces SIGSEGV.
 That is, verify that mysql_stmt_init  -> mysql_stmt_fetch is OK,
 or mysql_stmt_prepare -> mysql_stmt_fetch_column is OK and sets
 meaningful error.
 * remove alloc_stmt_fields call
 * revise stmt->state codes and statement states.
 * there are other items in prepared statements 'to fix' document.

Done:
 - cleanups and comments
 - revision of prepared statement error codes.
 - mysql_stmt_prepare is now can always be called (that is, you can reprepare
   a statement)
 - new implementation of mysql_stmt_close and fetch cancellation
