In the original code, qmp_get_command_list is used to construct a list of all commands' name. To get the information of all qga commands, it traverses the name list and search the command info with its name. So it can cause O(n^2) in the number of commands. This patch adds an interface to traverse the qmp command list by QmpCommand to replace qmp_get_command_list. It can decrease the complexity from O(n^2) to O(n).
