This commit adds the command and arguments to the torture.sh log file, and
also outputs the results directory. This latter allows impatient users
to quickly find the results that are being generated by the current run.

This commit adds --configs-rcutorture, --configs-locktorture, and
--configs-scftorture arguments to torture.sh, allowing the desired
set of scenarios to be passed to each. The default for each has been
changed from a large-system-appropriate set to just CFLIST for each.
Users are encouraged to create scripts that provide appropriate settings
for their specific systems.

Now that kvm.sh puts all the relevant details in the "log" file,
there is no need for torture.sh to generate a separate "log.long"
file. This commit therefore drops this from torture.sh.

This commit causes torture.sh to check for zero-length runs and to take
the cowardly option of refusing to run them, logging its cowardice for
later inspection.

This commit causes torture.sh to use the torture.verbose_sleep_frequency
kernel boot parameter to throttle verbose refscale output on large systems.

This commit places "---" markers in the torture.sh script's allmodconfig
output, and uses "<<" to avoid overwriting earlier output from this
build test.

This commit saves a few lines of code by creating a doyesno helper bash
function for argument parsing.

On large systems, the refscale printk() rate can overrun the file system's
ability to accept console log messages. This commit therefore uses the
new verbose_batched module parameter to rate-limit some of the higher-rate
printk() calls.

The .mod.c files created by allmodconfig builds interfers with the approach
torture.sh uses to enumerate types of rcuscale and refscale runs. This
commit therefore tightens the pattern matching to avoid this interference.

This commit uncomments the argument checking for the --duration argument
to torture.sh. While in the area, it also corrects the duration units
from seconds to minutes.

This commit improves torture.sh flexibility by autoscaling the number
of CPUs to be used in variable-CPUs torture tests, including scftorture,
refscale, rcuscale, and kvfree.

This commit adds the ability to do "make allmodconfig" to torture.sh,
given that normal rcutorture runs do not normally catch missing exports.

The bash "eval" command enables Bobby Tables attacks, which might not
be a concern in torture testing by themselves, but one could imagine
these combined with a cut-and-paste attack. This commit therefore gets
rid of them. This comes at a price in terms of bash quoting not working
nicely, so the "--bootargs" argument lists are now passed to torture_one
via a bash-variable side channel. This might be a bit ugly, but it will
also allow torture.sh to grow its own --bootargs parameter.
While in the area, add proper header comments for the bash functions.

This commit makes torture.sh use the new bash functions get_starttime()
and get_starttime_duration() created for kvm.sh.
