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.

This patch attempts to make the perf trace command-line for live-mode
commands more user-friendly and consistent with other perf commands.
The main change it makes is to allow <commands> to be run as part of
perf trace live-mode commands, as other perf commands do, instead of
the system-wide traces they're currently hard-coded to by the shell
scripts.
With this patch, the following live-mode trace now works as expected:
$ perf trace rw-by-pid ls -al
The previous system-wide behavior for this command would still be
available by explicitly specifying -a:
$ perf trace rw-by-pid -a ls -al
and if no <command> is specified, the output is also system-wide:
$ perf trace rw-by-pid
Because live-mode requires both record and report steps to be invoked,
it isn't always possible to know which args to send to the report and
which to send to the record steps - mainly this is the case for report
scripts with optional args - in those cases it would be necessary to
use separate 'perf trace record' and 'perf trace report' steps.
For example:
$ perf trace syscall-counts ls
Here we can't decide whether ls should be passed as a param to the
syscall-counts script or whether we should invoke ls as a <command>.
In these cases, we just say that we'll ignore optional script params
and always interpret the extra arguments as a <command>.
If the user instead wants the other interpretation, that can be
accomplished by using separate record and report commands explicitly:
$ perf trace record syscall-counts
$ perf trace report syscall-counts ls
So the rules that this patch implements, which seem to make the most
intuitive sense for live-mode commands:
- for commands with optional args and commands with no args, no args
are sent to the report script, all are sent to the record step
- for 'top' commands i.e. that end with 'top', <commands> can't be
used - all extra args are send to the report script as params
- for commands with required args, the n required args are taken to be
the first n args after the script name and sent to the report
script, and the rest are sent to the record step

Because the perf-trace shell scripts hard-coded the use of the
perf-record system-wide param, a perf trace record session was always
system wide, even if it was given a command.
If given a command, perf trace record now only records the events for
the command, as users expect.
If no command is given, or if the '-a' option is used, the recorded
events are system-wide, as before.

profile_cpu was left over from an earlier implementation that
supported running perf top on a single CPU. profile_cpu was no
longer set by any switch and usages of it resulted in dead code.
Instead, convert the code to use cpu_list, which is set by the
-C <cpu_list> option.
Also improved the printing of nr_cpus and cpu_list by correcting
the plurals.
