TODO :
- Don't bind so tightly the metadata with the result set. This means
that the metadata reading should not expect a MYSQLND_RES pointer, it
does not need it, but return a pointer to the metadata (MYSQLND_FIELD *).
For normal statements we will then just assign it to a member of
MYSQLND_RES. For PS statements, it will stay as part of the statement
(MYSQLND_STMT) between prepare and execute. At execute the new metadata
will be sent by the server, so we will discard the old one and then
finally attach it to the result set. This will make the code more clean,
as a prepared statement won't have anymore stmt->result != NULL, as it
is now, just to have where to store the metadata.
- Change mysqlnd_simple_command to accept a heap dynamic array of MYSQLND_STRING
terminated by a string with ptr being NULL. Thus, multi-part messages can be
sent to the network like writev() and this can save at least for
mysqlnd_stmt_send_long_data() new malloc. This change will probably make the
code in few other places cleaner.
