ktest: Add standalone config-bisect.pl program Started working on a stand alone program that can do a config bisect. It is based on the config bisect code of ktest.pl. Instead of needing all the infrastructure of ktest.pl, all that is required for config-bisect.pl is two config files. One that works, and one that does not. The goal is to pass in the two files, and it will create a new "good" and a new "bad" config file based on input from the user. After several iterations (calls to this program), it will eventually end with a minimum config value that allows one config to work and the other config to break. The program uses a technique that takes the good config and then makes half of the configs that differ from the bad config just like the bad config. The code will use make oldconfig to make sure the configs that are set are not all converted back due to incorrect dependencies on other configs set in the bad config but not in the new test config. This is still a work in progress, but as it was written while I was working at Red Hat, I want this code to be submitted as such. Signed-off-by: Steven Rostedt (Red Hat) <rostedt@goodmis.org>

ktest.pl: Have ktest.pl pass -r to config-bisect.pl to reset bisect If config-bisect.pl sees that a config_bisect has already been started, it will ask on the command line if it should bisect or not. This will mess up running config_bisect from ktest.pl. Have ktest.pl pass in '-r' to config-bisect.pl and have config-bisect.pl recognize that to reset without asking.
