The tracepoints used by the workqueue-stats script no longer exist so
trying to run the script results in:
# perf script record workqueue-stats
invalid or unsupported event: 'workqueue:workqueue_creation'
Run 'perf list' for a list of valid events
So remove the script until it can be reworked using the new workqueue
tracepoints.

The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it.
This problem was introduced in 133dc4c.

Set $PERF_EXEC_PATH before starting the record and report scripts, and
make them use it where necessary.

It should be possible to run any perf trace script in 'live
mode'. This requires being able to pass in e.g. '-i -' or other
args, which the current shell scripts aren't equipped to handle.
In a few cases, there are required or optional args that also
need special handling. This patch makes changes the current set
of shell scripts as necessary.

Lists the available perf trace scripts, one per line e.g.:
root@tropicana:~# perf trace -l
List of available trace scripts:
workqueue-stats workqueue stats (ins/exe/create/destroy)
wakeup-latency system-wide min/max/avg wakeup latency
rw-by-file <comm> r/w activity for a program, by file
check-perf-trace useless but exhaustive test script
rw-by-pid system-wide r/w activity
To be consistent with the other listing options in perf, the
current latency trace option was changed to '-L', and '-l' is
now used to access the script listing as:
To create the list, it searches each scripts/*/bin directory for
files ending with "-report" and reads information found in
certain comment lines contained in those shell scripts:
- if the comment line starts with "description:", the rest of the
line is used as a 'half-line' description. To keep each line in
the list to a single line, the description should be limited to 40
characters (the rest of the line contains the script name and
args)
- if the comment line starts with "args:", the rest of the line
names the args the script supports. Required args should be
surrounded by <> brackets, optional args by [] brackets.
The current scripts in scripts/perl/bin have also been updated
with description: and args: comments.

To capture the relevant events for a given Perl script and to
avoid having to continually remember and type in long
command-lines, add a scripts/perl/bin directory containing two
simple shell scripts for each Perl script, one for recording and
one for processing/display. For example, to record perf data for
the rw-by-pid.pl script, run scripts/perl/bin/rw-by-pid-record
and to actually run the script and display the output run
scripts/perl/bin/rw-by-pid-report.
