316c7136f8 perf tools: Finish the removal of 'self' arguments 
They convey no information, perhaps I was bitten by some snake at some
point, complete the detox by naming the last of those arguments more
sensibly.

765532c8 (perf script: Finish the rename from trace to script,
2010-12-23) made a mistake during find-and-replace replacing
"../../../util/trace-event.h" with "../../../util/script-event.h", a
non-existent file.  Fix this include.

5a1e99dd20 perf: net_dropmonitor: Fix symbol-relative addresses 
The comparison between traced and symbol addresses is backwards: if
the traced address doesn't exactly match a symbol (which we don't
expect it to), we'll show the next symbol and the offset to it,
whereas we should show the previous symbol and the offset from it.

b22e79395c perf perl scripts: Fix SIGALRM and pipe read race for rwtop 
Fixing rwtop script race. The issue is caused by rwtop script triggering
SIGALRM and underneath pipe reading layer reporting error when
interrupted.

Fixing this by setting SA_RESTART for rwtop SIGALRM handler, which
avoids interruption of the pipe reading layer.

1de7b7e89d perf script: Remove workqueue-stats script 
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.

0076d546b4 perf scripts python: Add event_analyzing_sample.py as a sample for general event handling 
Currently only trace point events are supported in perf/python script,
the first 3 patches of this serie add the support for all types of
events. This script is just a simple sample to show how to gather the
basic information of the events and analyze them.

This script will create one object for each event sample and insert them
into a table in a database, then leverage the simple SQL commands to
sort/group them. User can modify or write their brand new functions
according to their specific requirment.

Here is the sample of how to use the script:

 $ perf record -a tree
 $ perf script -s process_event.py

There is 100 records in gen_events table
Statistics about the general events grouped by thread/symbol/dso:

02f1c33f7d perf scripts python: Add a python library EventClass.py 
This library defines several class types for perf events which could
help to better analyze the event samples. Currently there are just a few
classes, PerfEvent is the base class for all perf events,  PebsEvent is
a HW base Intel x86 PEBS event, and user could add more SW/HW event
classes based on requriements.

63e03724b5 perf script: Add drop monitor script 
A while back I created the dropmonitor protocol, which allowed users to get
reports of dropped frames communicated to them via a netlink socket.

While useful, several people have now asked that I integrate the ability
to do drop monitoring with perf, so they don't have to run additional
tools.

This patch adds a drop monitor script to the perf suite, and provides
the same output that the netlink socket does.
