Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.

In addition to using refcounts for the struct thread lifetime management, we need to protect access to machine->threads from concurrent access. That happens in 'perf top', where a thread processes events, inserting and deleting entries from that rb_tree while another thread decays hist_entries, that end up dropping references and ultimately deleting threads from the rb_tree and releasing its resources when no further hist_entry (or other data structures, like in 'perf sched') references it. So the rule is the same for refcounts + protected trees in the kernel, get the tree lock, find object, bump the refcount, drop the tree lock, return, use object, drop the refcount if no more use of it is needed, keep it if storing it in some other data structure, drop when releasing that data structure. I.e. pair "t = machine__find(new)_thread()" with a "thread__put(t)", and "perf_event__preprocess_sample(&al)" with "addr_location__put(&al)". The addr_location__put() one is because as we return references to several data structures, we may end up adding more reference counting for the other data structures and then we'll drop it at addr_location__put() time.

Removing another global variable. This one tho would be better done by using the machine infrastructure, searching for the 'struct thread' with a pid, then using thread->priv, etc. TODO list material for now.

To avoid having all those global variables and to use the interface to event processing that is based on passing a 'perf_tool' struct that should be embedded in a per tool specific struct passed to all the sample processing callbacks. There are some more globals to move, next patches will do it.

Since b000c806 "tracing: Remove the extra 4 bytes of padding in events" removed padding bytes, perf timechart got out of sync with the kernel's trace_entry structure. Convert perf timechart to use dynamic fields offsets (via perf_evsel__intval) not relying on a hardcoded copy of fields layout from the kernel.

Add -g flag to `perf timechart record` which saves callchain info in the perf.data. When generating SVG, add backtrace information to the figure details, so now it's possible to see which code path woke up the task and why some task went to sleep.

Add titles to figures so we can run SVG interactively in Firefox and check event details in the tooltips. This also aids exploring SVG with Inkscape because when user clicks on one part of logical figure, all parts are selected. It's also possible to read titles with Inkscape in the object details.
