This patch just follows Robert Richter's idea and the commit 37a058ea0
"perf script: Add generic perl handler to process events"
to similarly add a python handler for general events other than tracepoints.
For non-tracepoint events, this patch will try to find a function named
"process_event" in the python script, and pass the event attribute,
perf_sample, raw_data in format of raw string. And the python script can
use "struct" module's unpack function to disasemble the needed info and process.

It was missing that only certain bit fields are passed to the config
value which confused users. Updating it.

Note: Though this should already work with O=$outputdir we better use
the OUTPUT variable directly.

We already lookup the associated event_format when reading the perf.data
header, so that we can cache the tracepoint name in evsel->name, so do
it a little further and save the event_format itself, so that we can
avoid relookups in tools that need to access it.
Change the tools to take the most obvious advantage, when they were
using pevent_find_event directly. More work is needed for further
removing the need of a pointer to pevent, such as when asking for event
field values ("common_pid" and the other common fields and per
event_format fields).
This is something that was planned but only got actually done when
Andrey Wagin needed to do this lookup at perf_tool->sample() time, when
we don't have access to pevent (session->pevent) to use with
pevent_find_event().

We only have access to pevent after processing that event, so set the
tracepoint names there.
Right now this isn't a problem as we're deferring resolving the
tracepoint names to when we process samples, but in the next patches we
will be doing it in advance, to avoid relookups, so do it earlier, as
soon as we process the tracing data event.

The ELSE IF statements do not work as expected if another ELSE statement
follows. This is because the $if_set is not set. If the ELSE IF
condition is true, the following ELSE should be ignored. But because the
$if_set is not set, the following ELSE will also be executed.

Changeset 0f6a3015:
"perf tools: Support user regs and stack in sample parsing"
uses hweight_long in evsel.c, so we need to drag util/hweight.c
to the python binding.
Ditto for ee8dd3c:
"perf tools: Change strlist to use the new rblist"
where we need to add util/rblist.c.
Now twatch.py works again:

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core fixes and some late updates from Arnaldo Carvalho de Melo:
* Make clean brace expansion fix for some shells, from Palmer Cox
* Warn user just once per guest kernel when not finding kernel info,
from David Ahern
* perf test fix from Jiri Olsa
* Fix error handling on event creation in perf top, from David Ahern
* Fix check on perf_target__strnerror, from Namhyung Kim
* Save the whole cmdline, from David Ahern
* Prep work for the DWARF CFI post unwinder, so that it doesn't
uses perf_session in lots of places, just evlist/evsel is enough.

The clean target uses brace expansion to remove some generated files. However,
the default shells on many systems do not support this feature resulting in
some generated files not being removed by clean.

'perf kvm top' shows a continual flurry of:
Can't find guest [5201]'s kernel information
if it can't find the guest info and with a lot of VMs running a user has no
chance of reading them all. Limit message to once per guest.

Replaces the direct use of rbtree code with the rblist API. In the end
the patch is a no-op on strlist functionality; the API for strlist is
not changed, only its implementaton.

rblist is the rbtree based code from strlist. It will be the common code
for strlist and the to-be-introduced intlist.

Only want to process directories under the guestmnount directory that
have a pid as a name (ie, all digits). Other entries in the guestmount
directory should be ignored. There is already a check that requires the
first character of each entry to be a digit, but atoi is used to convert
the directory name to a pid. For example if guestmount contains a
directory with the name 1foo, atoi converts it to a pid of 1 and a
machine is created with a pid of 1. This is wrong; this directory really
should be ignored. Use strtol to do that.

A number of builtin commands process some user args and then pass the rest to
cmd_record. cmd_record then saves argc/argv that it receives into the header of
the perf data file. But this loses the arguments handled by the first command
-- ie., the real command line from the user. This patch saves the command line
as typed by the user rather than what was passed to cmd_record.
As an example consider the command:
$ perf kvm --guest --host --guestmount=/tmp/guest-mount record
-fo /tmp/perf.data -ag -- sleep 10
Currently the command saved to the header is:
cmdline : /tmp/p3.5/perf record -o perf.data.kvm -fo /tmp/perf.data -ag -- sleep 1
(ignore the duplicated -o -- the first would be yet another bug with perf-kvm).
With this patch the command line saved to the header is:
cmdline : /tmp/p3.5/perf kvm --guest --host --guestmount=/tmp/guest-mount
record -fo /tmp/perf.data -ag -- sleep 1
v2: simplified to saving the command in parse_options per Stephane's suggestion

That is a more compact form of perf_session__parse_sample and to support

"fault-injection: add tool to run command with failslab or
fail_page_alloc" added tools/testing/fault-injection/failcmd.sh to make it
easier to inject slab/page allocation failures by fault injection.
failcmd.sh prints the following warning when running with arguments
for command.
# ./failcmd.sh echo aaa
failcmd.sh: line 209: [: echo: binary operator expected
aaa
This warning is caused by an improper check whether at least one
parameter is left after parsing command options.
Fix it by testing the length of $1 instead of $@

A large enough symbol size causes an overflow in the size parameter to
the histogram allocation, leading to a segfault in
symbol__inc_addr_samples later on when this histogram is accessed.
In the case of being called via perf-report, this returns back and
gracefully ignores the sample, eventually ignoring the chained return
value of perf_session_deliver_event in flush_sample_queue.

The TRACEEVENT-CFLAGS file is used to detect any change on compiler
flags. Just ignore it.

Cross compiling perf requires setting ARCH and CROSS_COMPILE variables,
but libtraceevent couldn't detect the changes so it ends up believing no
recompiling is required. Thus the linker failed like:
LINK perf
../lib/traceevent//libtraceevent.a: member ../lib/traceevent//libtraceevent.a(event-parse.o) in archive is not an object
collect2: ld returned 1 exit status
make: *** [perf] Error 1
This patch fixes this by adding TRACEEVENT-CFLAGS file like
PERF-CFLAGS to track those changes.

Bison 2.6 started to generate parse_events_parse() declaration in header. In
this case we have redundant redeclaration:
util/parse-events.c:29:5: error: redundant redeclaration of ‘parse_events_parse’ [-Werror=redundant-decls]
In file included from util/parse-events.c:14:0:
util/parse-events-bison.h:99:5: note: previous declaration of ‘parse_events_parse’ was here
cc1: all warnings being treated as errors
Let's disable -Wredundant-decls for util/parse-events.c since it includes
header we can't control.

Perf uses GNU-specific version of strerror_r(). The GNU-specific strerror_r()
returns a pointer to a string containing the error message. This may be either
a pointer to a string that the function stores in buf, or a pointer to some
(immutable) static string (in which case buf is unused).
In glibc-2.16 GNU version was marked with attribute warn_unused_result. It
triggers few warnings in perf:
util/target.c: In function ‘perf_target__strerror’:
util/target.c:114:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result]
ui/browsers/hists.c: In function ‘hist_browser__dump’:
ui/browsers/hists.c:981:13: error: ignoring return value of ‘strerror_r’, declared with attribute warn_unused_result [-Werror=unused-result]
They are bugs.
Let's fix strerror_r() usage.

There have one problem about hw_breakpoint perf event, as watched, the
events reported to userspace is not correctly, sometime one trigger
bp_event report several events, sometime bp_event cannot go through to
user.
The root cause is attr->freq is 1 passed to kernel defaultly in bp
events, this make kernel calculate event period not as expect, make
sample period to 1 will change attr->freq to 0, to fix this problem.
This patch is similar with commit f92128 about tracepoint events:
perf: Make the trace events sample period default to 1
