[GIT PULL] Add ktest.pl to tools/testing/ktest

Linus (et. al.)

As I announced at Kernel Summit, I created a simple kernel test program
that allows a developer to test their kernels with various randconfigs.

It also performs automated git bisects, and serial patch testing.

It can even do a config bisect, which I've used several times to find
that one config that breaks the kernel.

Each of these tests have three kinds of test types:

1) build - This is the simplest of the tests. It just makes sure that
the kernel compiles without error.

2) boot - This not only builds the kernel, but also makes sure that the
kernel boots. You need to have a way to read the console via stdout,
which the tool checks to see if you make it to a login prompt (or
something else if you change the config file).

3) test - This builds, and boots the kernel, and on success of booting,
it will execute some command. You could do a 'ssh host ...' to remotely
kick off a test. It can be any shell script that must exit with 0 on
success and non zero on error.

It comes with a very documented sample config file and a test (for me)
that makes sure all the options in ktest.pl exist also in the sample
config file, so I do not forget to document any new features.

Most of the configs have defaults that you do not need to worry about. I
could add lots of small sample configs for people to start with too.

Anyway, a lot of people asked me to push this into the kernel, so I'm
posting my pull request now. I've kept the history of the development in
the git tree. I'm not posting all the patches as I'm not sure people
care about them. Below is the diffstat and change log. For the final
result of ktest.pl your can see these files:
