If the log file for a given test is larger than the max size given then use
set the seek from the end of the log file instead of from the start of the
test.

The log file should be up to date to whatever is happening in ktest.
Disable buffering to the LOG output file handle.

Currently, every write to the log file is done by opening the file, writing
to it, then closing the file. This rather expensive. Just open it at the
beginning and close it at the end.

There is a NOT DEFINED operator, but there is not an operator that can
negate any other expression.
For example: NOT (${FOO} == boot || ${BAR} == run)
Add the keyword NOT to allow the ktest.pl config files to negate operators.

Currently, if a PRE_TEST is defined and ran, but fails, there's nothing
currently available to make the test fail too. Add a PRE_TEST_DIE option that
when set, if a PRE_TEST is defined and fails, the test will die too.

If a log file is defined and the test were to error, a print statement is
made that shows the user where the log file is to examine it further. But
this is not done if the test were to succeed.
I find it annoying that it does not show where the log file is on success,
as I run several different tests that place their log files in various
locations, and even though the test pass, there's things I want to look at
in the log file (like warnings). It is much easier to find where the log
file is, if it is displayed at the end of a test.

When performing a automatic config bisect via ktest.pl, it is very useful to
have a copy of each of the bisects used. This way, if a bisect were to go
wrong, it is possible to retrace the steps and continue at the location
before the error was made.
The ktest.pl will make a copy of the good and bad configs, labeled as such,
as well as a number attached to it that represents the iteration of the
bisect. These files are saved in the ktest temp directory where it currently
stores the good and bad config files.

Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.
Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

For the last time, I screwed up my ktest config file, and the build went
into the default "randconfig", blowing away the .config that I had set up.
The reason for the default randconfig was because when this was first
written, I wanted to do a bunch of randconfigs. But as time progressed,
ktest isn't about randconfig anymore, and because randconfig destroys the
config in the build directory, it's a dangerous default to have. Use
oldconfig as the default.

For BLS, kernel entry is added by kernel-install command through
POST_INSALL, for example,
POST_INSTALL = ssh root@Test "/usr/bin/kernel-install \
add $KERNEL_VERSION /boot/vmlinuz-$KERNEL_VERSION"
The entry is removed by kernel-install command and the kernel
version is needed for the argument.
Pass KERNEL_VERSION variable to POST_KTEST so that kernel-install
command can remove the entry like as follows:
POST_KTEST = ssh root@Test "/usr/bin/kernel-install remove $KERNEL_VERSION"

Unexpected power cycle occurs while the installation of the
kernel.
ssh root@Test sync ... [0 seconds] SUCCESS
ssh root@Test reboot ... [1 second] FAILED!
virsh destroy Test; sleep 5; virsh start Test ... [6 seconds] SUCCESS
That is because REBOOT, the default is "ssh $SSH_USER@$MACHINE
reboot", exits as 255 even if the reboot is successfully done,
like as:
]# ssh root@Test reboot
Connection to Test closed by remote host.
]# echo $?
255
]#
To avoid the unexpected power cycle, introduce a new parameter,
REBOOT_RETURN_CODE to judge whether REBOOT is successfully done
or not.

ktest fails if meta characters are in GRUB_MENU, for example
GRUB_MENU = 'Fedora (test)'
The failure happens because the meta characters are not escaped,
so the menu doesn't match in any entries in GRUB_FILE.
Use quotemeta() to escape the meta characters.

If a test has an error, display not only the what type of test failed, but
if the test was giving a name, display that too, as well as the current
iteration of the tests. Each test has an iteration number associated to it.
For error messages display that iteration number along with the test type
and test name. This includes the message that gets sent via email.

Pull ktest updates from Steven Rostedt:
"These commits have either been sitting in my INBOX or have been in my
local tree for some time. I need to push them upstream:
- Separate out config-bisect.pl from ktest.pl.
This allows users to do config bisects without full ktest setup.
- Email on status change.
Allow the user to be emailed on test start, finish, failure, etc.
- Other small fixes and enhancements"
