If the test failed due to timeout for boot, print a message saying
so. Otherwise the user will be confused to why their test just failed.

The command to run post install (for those that want initrds) was
broken. Instead of doing a substitution for the $KERNEL_VERSION
variable. It was replacing the entire command with nothing.

Currently, if a test causes constant output but never reaches a
boot prompt, or crashes, the test will never stop. Add STOP_TEST_AFTER
to create a variable that will stop (and fail) the test after it has run
for this amount of time. The default is 10 minutes. Setting this
variable to -1 will disable it.

Record the console of tests to both the console and the log.
Also, record the bug reports afte the test has completed.
Currently, if a kernel bug happens while running the userland
test, the test stops and will not record the kernel bug. This
makes it difficult to solve what happened.

The config STOP_AFTER_FAILURE is the number of seconds to continue
the test when a failure is detected. This lets the monitor record
more data to the logs and console that may be helpful in solving
the bug that was found.

But the test had a bug. If the failure caused multiple
"Call Trace" stack dumps, the start time to compare the
STOP_AFTER_FAILURE would constantly be reset. Only update the start
time at the first "Call Trace" instance.

Add the config option BISECT_FILES that allows the user to
specify what path in the kernel to run the git bisect on.
Signed-off-by: NSteven Rostedt <rostedt@goodmis.org>

If a during a git bisect, ktest fails on something other than
what it is testing (if BISECT_TYPE is test but it fails on build),
if BISECT_SKIP is set, then it will do a "git bisect skip" instead
of just failing the bisect and letting the user find a good commit
to test.
Signed-off-by: NSteven Rostedt <rostedt@goodmis.org>

For both git bisect and config bisect, if BISECT_MANUAL is set to 1,
then bisect will stop between iterations and ask the user for the
result. The actual result is ignored. This makes it possible to
use ktest.pl for bisecting configs and git and let the user examine
the results themselves and enter their own results.
Signed-off-by: NSteven Rostedt <rostedt@goodmis.org>

When bisecting, one may come across a kernel that does not have
make oldnoconfig. In this case, we need to run the command "yes"
into a make oldconfig. This will select defaults instead of 'n'
into each command, but it works as a work around.

Note, "yes n" will not work because a config may have a value that
"n" is not acceptable for.

Currently we just look for a Call Trace to start the time out
when to reboot the box. But if the kernel panics and does not
show a Call Trace, the test will not reboot the box after
the specified timeout.

In keeping with the notion that all tools should be simple for
all to use. I've changed ktest.pl to ask for mandatory options
instead of just failing. It will append (or create) the options
the user types in, onto the config file.

During the config_bisect, in case of failure, it is nice to have
the last good and bad .configs that were used. This would let
us restart the config_bisect from those configs.

Copy the last good config into the output dir as config_good,
and the last bad config as config_bad.

Added the options STOP_AFTER_SUCCESS and STOP_AFTER_FAILURE to
allow the user to give a time (in seconds) to stop the monitor
after a stack trace or login has been detected. Sometimes the
kernel constantly prints out to the console and this may cause
the test to run indefinitely.

When we store failures, we create a directory that has the build_type
in it. For useconfig, it also contains the name path of the config
file it uses. This unfortunately gets its own directory on failure.
Parse off the directory name when creating the directory to store
the failures.

Added the ability to do a config_bisect. It starts with a bad
config and does the following loop.

	Enable half the configs.
	if none of the configs to check are not enabled
	 (caused by missing dependencies) enable the other half.
	Run the test
	if the test passes, remove the configs from the check
	  but enabled them for further tests (to satisfy
	  dependencies).
	else
	  Remove any config that was not enabled, as we have found
	  a new config that can cause a failure.
	loop till we have only one config left.

Change the config to use TEST_START where the options after a
TEST_START automatically get the [] as it is read and they do
not need to exist in the config file;

TEST_START
MIN_CONFIG = myconfig

is the same as

MIN_CONFIG[1] = myconfig

The benefit is that you no longer need to keep track of test numbers
with tests.

Also process the commit ids that are passed to the options
to get the actually SHA1 so it is no longer relative to the branch.
Ie, saying HEAD will get the current SHA1 and then that will
be used, and will work even if another branch is checked out.

It is much better to keep the monitor running throughout a
