Renames:
mysql_bind_param      -> mysql_stmt_bind_param
mysql_bind_result     -> mysql_stmt_bind_result
mysql_execute         -> mysql_stmt_execute
mysql_fetch           -> mysql_stmt_fetch
mysql_fetch_column    -> mysql_stmt_fetch_column
mysql_get_metadata    -> mysql_stmt_result_metadata
mysql_param_count     -> mysql_stmt_param_count
mysql_param_result    -> mysql_stmt_param_metadata
mysql_prepare         -> mysql_stmt_prepare
mysql_send_long_data  -> mysql_stmt_send_long_data

client_test.c cleaned up from memory leaks


include/mysql.h:
  New call mysql_stmt_init() introduced.
  Renames:
  mysql_bind_param      -> mysql_stmt_bind_param
  mysql_bind_result     -> mysql_stmt_bind_result
  mysql_execute         -> mysql_stmt_execute
  mysql_fetch           -> mysql_stmt_fetch
  mysql_fetch_column    -> mysql_stmt_fetch_column
  mysql_get_metadata    -> mysql_stmt_result_metadata
  mysql_param_count     -> mysql_stmt_param_count
  mysql_param_result    -> mysql_stmt_param_metadata
  mysql_prepare         -> mysql_stmt_prepare
  mysql_send_long_data  -> mysql_stmt_send_long_data
  Renames are done according to the rule 'Everything call operating with
  'MYSQL_STMT' structure has 'mysql_stmt_' prefix.
  Additionally mysql_param_result was renamed to mysql_stmt_param_metadata
  and mysql_get_metadata to mysql_stmt_result_metadata.
  All renames are done in hope that new names are easier to remember and 
  understand.
