Now we don't anymore use popen to run 'perf annotate' for the selected symbol, instead we collect per address samplings when processing samples in 'perf report' if we're using the newt browser, then we use this data directly to do annotation. Done this way we can actually traverse the objdump_line objects directly, matching the addresses to the collected samples and colouring them appropriately using lower level slang routines. The new ui_browser class will be reused for the main, callchain aware, histogram browser, when it will be made generic and don't assume that the objects are always instances of the objdump_line class maintained using list_heads.

Initially this was just to be able to have a printf like method to prepare the formatted string and then pass to newtPushHelpLine, but as we already have for ui_progress, etc, its a step in identifying a restricted, highlevel set of widgets we can then have implementations for multiple widget sets (GTK, etc).

For Fedora, I want to force perf to link against libiberty.a for cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity on binutils. (libiberty is LGPL2, libbfd is GPL3.) If we just rely on autodetection, we'll end up with libbfd linked against us, since they're both in binutils-static in the buildroot.

In cbbc79a5 we introduced support for multiple events by introducing a new "event_stat_id" struct and then made several perf_session methods receive a point to it instead of a pointer to perf_session, and kept the event_stats and hists rb_tree in perf_session. While working on the new newt based browser, I realised that it would be better to introduce a new class, "hists" (short for "histograms"), renaming the "event_stat_id" struct and the perf_session methods that were really "hists" methods, as they manipulate only struct hists members, not touching anything in the other perf_session members. Other optimizations, such as calculating the maximum lenght of a symbol name present in an hists instance will be possible as we add them, avoiding a re-traversal just for finding that information. The rationale for the name "hists" to replace "event_stat_id" is that we may have multiple sets of hists for the same event_stat id, as, for instance, the 'perf diff' tool has, so event stat id is not what characterizes what this struct and the functions that manipulate it do.

We have just one host on a given session, and that is the most common setup right now, so embed a ->host_machine struct machine instance directly in the perf_session class, check if we're looking for it before going to the rb_tree.
