The perf_target_errno enumerations are used to indicate specific error
cases on perf target operations. It'd help libperf being a more generic
library.

Currently, 'perf record -- sleep 1' creates a cpu map for all online
cpus since it turns out calling cpu_map__new(NULL). Fix it.
Also it is guaranteed that cpu_list is NULL if PID/TID is given by
calling perf_target__validate(), so we can make the conditional bit
simpler.
This also fixes perf test 7 (Validate) failure on my 6 core machine:
$ cat /sys/devices/system/cpu/online
0-11
$ ./perf test -v 7
7: Validate PERF_RECORD_* events & perf_sample fields:
--- start ---
perf_evlist__mmap: Operation not permitted
---- end ----
Validate PERF_RECORD_* events & perf_sample fields: FAILED!

Check if neither of --pid, --tid or --uid was specified and if so, set
system_wide appropriately.
Namhyung's patch would make using any of the above target specifiers
emit a warning in perf_target__validate, since it would see
target.system_wide set and one of the others as well.
So set system_wide after validation.

Currently if we cannot decide the size of the event, we guess next
event possition by:
"... check alignment, and increment a single u64 in the hope
to catch on again 'soon'"
This usually ends up with segfault or endless loop. It's better
to admit the failure right away, then pretend nothing happened.
It makes the life easier ;)

There were some combinations of these switches that are not so
appropriate IMHO.
Since there are implicit priorities between them and they worked well
anyway, but it ends up opening useless duplicated events.
For example, 'perf stat -t <pid> -a' will open multiple events for the
thread instead of one.
Add explicit checks and warn user in perf_target__validate().

This allows comparing performance of different applications with each

With this patch, the header now reads (for example):
Samples: 5K of event 'instructions'
Event count (approx.): 2993026545

<SNIP>
ffffffff81265494: mov %rdi,%rcx
Since we now have objdump_line allowing tools to print the offset
independently from the rest of the line, allow toggling a view where
just offsets from the start of the function are shown:
2f: jne ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
84: mov %rdi,%rcx
The offset view will be the default as soon as operations that deal with
offsets in a function are handled accodringly, i.e. in offset view the
above will become:
2f: jne __list_del_entry+0x84
<SNIP>
84: mov %rdi,%rcx
And then a follow up patch will allow navigating thru jumps, just like

Tools that want to change parts of the line to a different color and
then restore the previous one will use this, starting with the annotate
browser that will change the color of addresses if not on the current
entry, i.e. the selected one.

This routine was checking only if the provided address was after
sym->end, not if it was before sym->start.
Fix that by checking for both and return in both cases -ERANGE, so that
tools can communicate this to the user properly, or if they chose so, to
abort.
This problem was reported previously but the fixes involved either doing
what was being done for the > end case, i.e. silently drop the sample,
returning 0, or aborting at this function, which is in a lib (or better,
is slated to be at some point) and shouldn't abort.
The 'report' tool already checks this value and uses pr_debug to warn
the user.
This patch makes the 'top' tool check it too and warn once per map where
such range problem takes place.

If there's an event with no samples in data file, the perf report
command can segfault after entering the event details menu.
Following steps reproduce the issue:
# ./perf record -e syscalls:sys_enter_kexec_load,syscalls:sys_enter_mmap ls
# ./perf report
# enter '0 syscalls:sys_enter_kexec_load' menu
# pres ENTER twice
Above steps are valid assuming ls wont run kexec.. ;)
The check for sellection to be NULL is missing. The fix makes sure it's
being check. Above steps now endup with menu being displayed allowing
'Exit' as the only option.

When a process exec()'s, all the maps are retired, but we keep the hist
entries around which hold references to those outdated maps.
If the same library gets mapped in for which we have hist entries, a new
map will be created. But when we take a perf entry hit within that map,
we'll find the existing hist entry with the older map.
This causes symbol translations to be done incorrectly. For example,
the perf entry processing will lookup the correct uptodate map entry and
use that to calculate the symbol and DSO relative address. But later
when we update the histogram we'll translate the address using the
outdated map file instead leading to conditions such as out-of-range
offsets in symbol__inc_addr_samples().
Therefore, update the map of the hist_entry dynamically at lookup/
creation time.

We were only decaying the entries for the offsets that were associated
with an objdump line.
That way, when we accrued the whole instruction addr range, more than
100% was appearing in some cases in the live annotation TUI.
Fix it by not traversing the source code line at all, just iterate thru
the complete addr range decaying each one.

We were not noticing it because symbol__inc_addr_samples was erroneously
dropping samples that hit the last byte in a function.
Working on a fix for a problem reported by David Miller, Stephane
Eranian and Sorin Dumitru, where addresses < sym->start were causing
problems, I noticed this other problem.

If DIE entries corresponding to declarations appear before definition

for a definition entry.
