Suppressing the mode when O_CREAT not present, needs improvements on the

For some dsos (e.g., libc, libpthread, kernel modules) the symbol offset
is huge. e.g.,
qemu-kvm 17238/17242 [007] 762235.640311:
ffffffff816288a1 __schedule+0x451 ([kernel.kallsyms])

It seems to be maps with a non-0 start. Taking that into account the
offsets are correct:

That uses the arg mask mechanism just introduced to suppress ignored

Based on an initial patch from David Ahern that showed the need for some
way to allow args to tell how many further args should be shown.

perf_evlist__config() must be moved to a separate source file to avoid
Python link errors when adding support for PERF_SAMPLE_IDENTIFIER.
It is appropriate to do this because perf_evlist__config() is a helper
function for event recording. It is used by tools to apply recording
options to perf_evlist. It is not used by the Python API.

Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.
Note that callers sometimes want to find the main thread
which has the memory maps. The main thread has tid == pid
so the usage in that case is:
machine__findnew_thread(machine, pid, pid)
whereas the usage to find the specific thread is:
machine__findnew_thread(machine, pid, tid)

The mmap syscalls, for instance, don't have the FORMAT_IS_POINTER for
its pointer arguments, override it.
This also paves the way for more specialized argument beautifiers, like
for mmap's prot and flags arguments.

event_format->flags has a FIELD_IS_POINTER, but it is not set for
the sys_exit 'ret' field in syscalls like mmap, so we need a way to
ask for hex printing for pointer returns and keep things like 'read'
returns printing in decimal.

Occassionally events (e.g., context-switch, sched tracepoints) are losing
the conversion of sample data associated with a thread. For example:
$ perf record -e sched:sched_switch -c 1 -a -- sleep 5
$ perf script
<selected events shown>
ls 30482 [000] 1379727.583037: sched:sched_switch: prev_comm=ls prev_pid=30482 ...
ls 30482 [000] 1379727.586339: sched:sched_switch: prev_comm=ls prev_pid=30482 ...
:30482 30482 [000] 1379727.589462: sched:sched_switch: prev_comm=ls prev_pid=30482 ...
The last line lost the conversion from tid to comm. If you look at the events
(perf script -D) you see why - a SAMPLE event is generated after the EXIT:
0 1379727589449774 0x1540b0 [0x38]: PERF_RECORD_EXIT(30482:30482):(30482:30482)
0 1379727589462497 0x1540e8 [0x80]: PERF_RECORD_SAMPLE(IP, 1): 30482/30482: 0xffffffff816416f1 period: 1 addr: 0
... thread: :30482:30482
When perf processes the EXIT event the thread is moved to the dead_threads
list. When the SAMPLE event is processed no thread exists for the pid so a new
one is created by machine__findnew_thread.
This patch address the problem by delaying the move to the dead_threads list
until the tid is re-used (per Adrian's suggestion).
With this patch we get the previous example shows:
ls 30482 [000] 1379727.583037: sched:sched_switch: prev_comm=ls prev_pid=30482 ...
ls 30482 [000] 1379727.586339: sched:sched_switch: prev_comm=ls prev_pid=30482 ...
ls 30482 [000] 1379727.589462: sched:sched_switch: prev_comm=ls prev_pid=30482 ...
and
0 1379727589449774 0x1540b0 [0x38]: PERF_RECORD_EXIT(30482:30482):(30482:30482)
0 1379727589462497 0x1540e8 [0x80]: PERF_RECORD_SAMPLE(IP, 1): 30482/30482: 0xffffffff816416f1 period: 1 addr: 0
... thread: ls:30482
v4: per Arnaldo's request add dead flag to thread struct and set when task exits
v3: re-do from a time based check to a delayed move to dead_threads list
v2: Rebased to latest perf/core branch. Changed time comparison to use
a macro which explicitly shows the time basis

The python/perf.so python binding links a subset of objects.
Re-implement 'verbose' and 'eprintf' so they (and consequently
'pr_debug') can be used in objects linked into pythin/perf.so.
Note 'eprintf' must be re-implemented because the full version links the
browser ui.

perf stat -a needs 10 open file descriptors per logical CPU
perf stat -a -dddd needs 20 open fds for each.
This implies that stat -a doesn't work on any system with the default
ulimit -n 1024 which has more than ~100 CPUs and stat -a -dddd doesn't
work on anything with more than 46 CPUs.
Longer term there needs to be probably some way to lower the file
descriptor requirements. This would need some changes in the kernel/user
interface.
But short term this patch just tries to increase the file descriptor
limit in perf itself, when it runs into a EMFILE.
It first sets it to the hard limit, and then tries to increase the hard
limit.
On Fedora systems the default seems to be soft limit 1024 and hard limit
4*1024. So even non root can support 409 or 186 CPUs respectively. root
can go far higher.

This patch improves the robustness of the build_cpu_topo() routine by
allowing either the CPU parsing or the thread parsing to fail and yet
get perf to produce some topology data which could be useful for the
analysis.
Without this patch, if the cpu parsing fails, the thread parsing is not
attempted vice-versa.
