Using accessors will make it easier to add reference count checking in
later patches.
Committer notes:
thread->nsinfo wasn't wrapped as it is used together with
nsinfo__zput(), where does a trick to set the field with a refcount
being dropped to NULL, and that doesn't work well with using
thread__nsinfo(thread), that loses the &thread->nsinfo pointer.
When refcount checking is added to 'struct thread', later in this
series, nsinfo__zput(RC_CHK_ACCESS(thread)->nsinfo) will be used to
check the thread pointer.

Later changes will add reference count checking for struct map, with
dso being the most frequently accessed variable. Add an accessor so
that the reference count check is only necessary in one place.
Additional changes:
- add a dso variable to avoid repeated map__dso calls.
- in builtin-mem.c dump_raw_samples, code only partially tested for
dso == NULL. Make the possibility of NULL consistent.
- in thread.c thread__memcpy fix use of spaces and use tabs.

Introduce functions to access struct maps. These functions reduce the
number of places reference counting is necessary. While tidying APIs do
some small const-ification, in particlar to unwind_libunwind_ops.
Committer notes:
Fixed up tools/perf/util/unwind-libunwind.c:
- return ops->get_entries(cb, arg, thread, data, max_stack);
+ return ops->get_entries(cb, arg, thread, data, max_stack, best_effort);

Python scripting can be used without libtraceevent. In particular,
scripting for Intel PT does not use tracepoints, and so does not need
libtraceevent support.
Alter the build and employ conditional compilation to allow Python
scripting without libtraceevent.
Example:
Before:
$ ldd `which perf` | grep -i python
$ ldd `which perf` | grep -i libtraceevent
$ perf record -e intel_pt//u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.031 MB perf.data ]
$ perf script intel-pt-events.py |& head -3
Error: Couldn't find script `intel-pt-events.py'
See perf script -l for available scripts.
After:
$ ldd `which perf` | grep -i python
libpython3.10.so.1.0 => /lib/x86_64-linux-gnu/libpython3.10.so.1.0 (0x00007f4bac400000)

Added Python 3 support while keeping Python 2.7 compatibility.
Committer notes:
This doesn't make it to auto detect python 3, one has to explicitely ask
it to build with python 3 devel files, here are the instructions
provided by Jaroslav:
---
$ cp -a tools/perf tools/python3-perf
$ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 all
$ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 all
$ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 DESTDIR=%{buildroot} install-python_ext
$ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 DESTDIR=%{buildroot} install-python_ext
---
We need to make this automatic, just like the existing tests for checking if
the python2 devel files are in place, allowing the build with python3 if
available, fallbacking to python2 and then just disabling it if none are
available.
So, using the PYTHON variable to build it using O= we get:
Before this patch:
$ rpm -q python3 python3-devel
python3-3.6.4-7.fc27.x86_64
python3-devel-3.6.4-7.fc27.x86_64
$ rm -rf /tmp/build/perf/ ; mkdir -p /tmp/build/perf ; make O=/tmp/build/perf PYTHON=/usr/bin/python3 -C tools/perf install-bin
make: Entering directory '/home/acme/git/linux/tools/perf'
<SNIP>
Makefile.config:670: Python 3 is not yet supported; please set
Makefile.config:671: PYTHON and/or PYTHON_CONFIG appropriately.
Makefile.config:672: If you also have Python 2 installed, then
Makefile.config:673: try something like:
Makefile.config:674:
Makefile.config:675: make PYTHON=python2
Makefile.config:676:
Makefile.config:677: Otherwise, disable Python support entirely:
Makefile.config:678:
Makefile.config:679: make NO_LIBPYTHON=1
Makefile.config:680:
Makefile.config:681: *** . Stop.
make[1]: *** [Makefile.perf:212: sub-make] Error 2
make: *** [Makefile:110: install-bin] Error 2
make: Leaving directory '/home/acme/git/linux/tools/perf'
$
After:
$ make O=/tmp/build/perf PYTHON=python3 -C tools/perf install-bin
$ ldd ~/bin/perf | grep python
libpython3.6m.so.1.0 => /lib64/libpython3.6m.so.1.0 (0x00007f58a31e8000)
$ rpm -qf /lib64/libpython3.6m.so.1.0
python3-libs-3.6.4-7.fc27.x86_64
$
Now verify that when using the binding the right ELF file is loaded,
using perf trace:
$ perf trace -e open* perf test python
0.051 ( 0.016 ms): perf/3927 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC ) = 3
<SNIP>
18: 'import perf' in python :
8.849 ( 0.013 ms): sh/3929 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC ) = 3
<SNIP>
25.572 ( 0.008 ms): python3/3931 openat(dfd: CWD, filename: /tmp/build/perf/python/perf.cpython-36m-x86_64-linux-gnu.so, flags: CLOEXEC) = 3
<SNIP>
Ok
<SNIP>
$
And using tools/perf/python/twatch.py, to show PERF_RECORD_ metaevents:
$ python3 tools/perf/python/twatch.py
