Since it is safe to call perf_evlist__close() multiple times, autoclose
it and remove the calls to the close from existing tools, reducing the

To be consistent with other places, use just 'evlist' for the evsel list

When a tool uses perf_evlist__start_workload and the supplied workload
fails (e.g.: its binary wasn't found), perror was being used to print
the error reason.
This is undesirable, as the caller may be a GUI, when it wants to have
total control of the error reporting process.
So move to using sigaction(SA_SIGINFO) + siginfo_t->sa_value->sival_int
to communicate to the caller the errno and let it print it using the UI
of its choosing.

Support basic dwarf(debuginfo) based operations for uprobe events. With
this change, perf probe can analyze debuginfo of user application binary
to set up new uprobe event.
This allows perf-probe --add(with local variables, line numbers) and
--line works with -x option. (Actually, --vars has already accepted -x
option)
For example, the following command shows the probe-able lines of a given
user space function. Something that so far was only available in the
'perf probe' tool for kernel space functions:
# ./perf probe -x perf --line map__load
<map__load@/home/fedora/ksrc/linux-2.6/tools/perf/util/map.c:0>
0 int map__load(struct map *map, symbol_filter_t filter)
1 {
2 const char *name = map->dso->long_name;
int nr;
5 if (dso__loaded(map->dso, map->type))
6 return 0;
8 nr = dso__load(map->dso, map, filter);
9 if (nr < 0) {
10 if (map->dso->has_build_id) {
And this shows the available variables at the given line of the
function.
# ./perf probe -x perf --vars map__load:8
Available variables at map__load:8
@<map__load+96>
char* name
struct map* map
symbol_filter_t filter
@<map__find_symbol+112>
char* name
symbol_filter_t filter
@<map__find_symbol_by_name+136>
char* name
symbol_filter_t filter
@<map_groups__find_symbol_by_name+176>
char* name
struct map* map
symbol_filter_t filter
And lastly, we can now define probe(s) with all available
variables on the given line:
# ./perf probe -x perf --add 'map__load:8 $vars'
Added new events:
probe_perf:map__load (on map__load:8 with $vars)
probe_perf:map__load_1 (on map__load:8 with $vars)
probe_perf:map__load_2 (on map__load:8 with $vars)
probe_perf:map__load_3 (on map__load:8 with $vars)
You can now use it in all perf tools, such as:
perf record -e probe_perf:map__load_3 -aR sleep 1
Changes from previous version:
- Add examples in the patch description.
- Use .text section start address and dwarf symbol address
for calculating the offset of given symbol, instead of
searching the symbol in symtab again.
With this change, we can safely handle multiple local
function instances (e.g. scnprintf in perf).

Expand given path to absolute path in the option parser, except for a
module name.
Since realpath at later stage in processing several probe point, can be
called several times (even if currently doesn't, it can happen when we
expands the feature), it is waste of the performance.
Processing it once at the early stage can avoid that.
Changes from previous one:
- Fix not to print null string.
- Allocate memory for given path/module name everytime.

Currently, if we use perf kvm --guestkallsyms --guestmodules report, we
can not get the perf information from perf data file. All sample are
shown as unknown.
Reproducing steps:
# perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.624 MB perf.data.guest (~27260 samples) ]
# perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules report |grep %
100.00% [guest/6471] [unknown] [g] 0xffffffff8164f330
This bug was introduced by 207b57926 (perf kvm: Fix regression with guest machine creation).
In original code, it uses perf_session__find_machine(), it means we deliver symbol to machine
which has the same pid, if no machine found, deliver it to *default* guest. But if we use
perf_session__findnew_machine() here, if no machine was found, new machine with pid will be built
and added. Then the default guest which with pid == 0 will never get a symbol.
And because the new machine initialized here has no kernel map created, the symbol delivered to
it will be marked as "unknown".
This patch here is to revert commit 207b57926 and fix the SEGFAULT bug in another way.
Verification steps:
# ./perf kvm --guestkallsyms /home/kallsyms --guestmodules /home/modules record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.651 MB perf.data.guest (~28437 samples) ]

The addr_location struct should fully qualify an address, and to do that
it should have in it the machine where the thread was found.
Thus all functions that receive an addr_location now don't need to also
receive a 'machine', those functions just need to access al->machine
instead, just like it does with the other parts of an address location:
al->thread, al->map, etc.

Reduce typing, functions use class__method convention, so unlikely to
clash with other libraries.

Its a local struct and the functions use the __ separator from the class
name to the method name, so its unlikely that this will clash with other
namespaces.
Save some typing then.

1. Since all callers either test if it is less than zero or assign its
result to an int variable, convert it from ssize_t to int;
2. There is just one use for the 'session' variable, so use rec->session
directly instead;
3. No need to store the result of perf_data_file__write, since that
result is either 'size' or -1, the later making the error result to
be stored in 'errno' and accessed thru printf's %m in the pr_err
call.

The commit 09600e0f9ebb ("perf tools: Compare dso's also when comparing
symbols") added a comparison of dso when comparing symbol.
But if the sort key already has dso, it doesn't need to do it again
since entries have a different dso already filtered out.
