If an user gives both of --symfs and --vmlinux option, the vmlinux will
be searched under the symfs directory.  This is somewhat confusing since
vmlinux often lives in kernel build directory or somewhere other than
user space binaries.

So it'd be better not adding symfs prefix for a vmlinux if it has an
absolute pathname.

Boris just raised another variant of building perf tools which is
broken:

 $ make tools/perf
 ...
     LINK /home/robert/cx/linux/tools/perf/perf
 gcc: error: ../linux/tools/lib/lk/liblk.a: No such file or directory

The variant wasn't considered by:

 107de372 perf tools: Fix build errors with O and DESTDIR make vars set

There are other variant of building perf too:

 $ make -C tools perf
 $ make -C tools/perf

Plus variants with O= and DESTDIR set.

This patch fixes the above and was tested with the following:

 $ make O=... DESTDIR=... tools/perf
 $ make O=... DESTDIR=... -C tools/ perf
 $ make O=... DESTDIR=... -C tools/perf
 $ make tools/perf
 $ make -C tools/ perf
 $ make -C tools/perf

It's kept as deprecated, resulting in error when processed in

The only user of the event types data is 'perf timechart' command and
uses this info to identify proper tracepoints based on its name.

Switching this code to use tracepoint callbacks handlers same as another
commands like builtin-{kmem,lock,sched}.c using the
perf_session__set_tracepoints_handlers function.

This way we get rid of the only event types user and can remove them
completely in next patches.

For example, in an application with an expensive function implemented
with deeply nested recursive calls, the default call-graph presentation
is dominated by the different callchains within that function.  By
ignoring these callees, we can collect the callchains leading into the
function and compactly identify what to blame for expensive calls.

For example, in this report the callers of garbage_collect() are
scattered across the tree:

  $ perf report -d ruby 2>- | grep -m10 ^[^#]*[a-z]
      22.03%     ruby  [.] gc_mark
                 --- gc_mark
                    |--59.40%-- mark_keyvalue
                    |          st_foreach
                    |          gc_mark_children
                    |          |--99.75%-- rb_gc_mark
                    |          |          rb_vm_mark
                    |          |          gc_mark_children
                    |          |          gc_marks
                    |          |          |--99.00%-- garbage_collect

If we ignore the callees of garbage_collect(), its callers are coalesced:

  $ perf report --ignore-callees garbage_collect -d ruby 2>- | grep -m10 ^[^#]*[a-z]
      72.92%     ruby  [.] garbage_collect
                 --- garbage_collect

The 'machine' parameter is unused in 'perf_event__repipe_synth()' and
some callers pass NULL anyway.  So remove it.

The 'rules' means that every second line of the tree view has a shaded
background, which makes it easier to see which cell belongs to which
row in the tree view.  It can be useful for a tree view that has a lot
of rows.

Sometimes it's annoying to see when some symbols have very wierd long
names.  So it might be a good idea to make column size changable.

For some reason it consumed quite amount of compile time when declared
as local variable, and it disappeared when moved out of the function.
Moving other variables/tables didn't help.

On my system this single-file-change build time reduced from 11s to 3s.

It's confusing to have same name for two difference functions which does
something opposite way.  Since what they do in this file is read *AND*
writing some of tracing metadata files, rename them to record_*() looks
better to me.
