perf trace/scripting: Enable scripting shell scripts for live mode

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.

perf trace/scripting: List available scripts

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.

perf trace/scripting: Add support for script args

One oversight of the original scripting_ops patch was a lack of
support for passing args to handler scripts. This adds
argc/argv to the start_script() scripting_op, and changes the
rw-by-file script to take 'comm' arg rather than the 'perf'
value currently hard-coded. It also takes the opportunity to do
some related minor cleanup.

perf trace: Add a scripts/perl/bin for perf trace shell scripts

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.
