support: Add optstring support
This patch adds an option to test to add small command line option through CMDLINE_OPTSTRING define. For instance: #define CMDLINE_OPTSTRING "vd" static void cmdline_process_function (int c) { switch (c): 'v': /* process '-v' option. */ break; 'd': /* process '-d' option. */ break; } #define CMDLINE_PROCESS cmdline_process_function It will add both '-v' and '-d' along with already default long options. * support/support_test_main.c (support_test_main): Use optstring member for option string in getopt_long. * support/test-driver.c: Add comment about CMDLINE_OPTSTRING. (CMDLINE_OPTSTRING): New define. * support/test-driver.h (test_config): Add optstring member.
