For long running sessions with many threads with short lifetimes the
amount of memory that the buildid process takes is too much.
Since we don't have hist_entries that may be pointing to them, we can
just release the resources associated with each thread when the exit
(PERF_RECORD_EXIT) event is received.
For normal processing we need to annotate maps with hits, and thus
hist_entries pointing to it and drop the ones that had none. Will be
done in a followup patch.

Changes:
* Simplification of the main search loop on dso__load()
* Replace the search with a 2-pass search:
* First, try to find an image with a proper symtab.
* Second, repeat the search, accepting dynsym.
A second scan should only ever happen when needed debug images are
missing from the buildid cache or stale, i.e., when the cache is out of
sync.
Currently, the second scan also happens when using separated debug
images, since the caching logic doesn't currently know how to cache
those. Improvements to the cache behaviour ought to solve that.

If we have a buildid, then we never want to load an image which has no buildid,
or which has a different buildid, so it makes sense for the check to be built
into dso__load and not done separately. This is fine for old distros which
don't use buildid at all since we do no check in that case.
This refactoring also alleviates some subtle race condition issues by not
opening ELF images twice to check the buildid and then load the symbols, which
could lead to weirdness if an image is replaced under our feet.

The stock newt checkbox tree widget we were using was not really
suitable for hist entry + callchain browsing.
The problems with it were manifold:
- We needed to traverse the whole hist_entry rb_tree to add each entry +
callchains beforehand.
- No control over the colors used for each row
So a new tree widget, based mostly on slang, was written.
It extends the ui_browser class already used for annotate to allow the
user to fold/unfold branches in the callchains tree, using extra fields
in the symbol_map class that is embedded in hist_entry and
callchain_node instances to store the folding state and when changing
this state calculates the number of rows that are produced when showing
a particular hist_entry instance.
This greatly speeds up browsing as we don't have to upfront touch all
the entries and only calculate callchain related operations when some
callchain branch is actually unfolded.
The memory footprint is also reduced as the data structure is not
duplicated, just some extra fields for controling callchain state and to
simplify the process of seeking thru entries (nr_rows, row_offset) were
added.

Hists have their hits increased by the event period. And this
period based counting is the foundation of all the stats in
perf report.
But callchains still use the raw number of hits, without taking
the period into account. So when we compute the percentage,
absolute based percentages are totally broken, and relative ones
too in the first parent level. Because we pass the number of events
muliplied by their period as the total number of hits to the
callchain filtering, while callchains expect this number to be
the number of raw hits.
perf report -g graph was simply not working, showing no graph unless
the min percent was zero. And even there the percentage of the
branches was always 0. And may be fractal filtering was broken on
the first branch level too.
flat also was broken, but it was hidden because of other breakages.
Anyway fix this by counting using periods on callchains.

Initialize the callchain radix tree root correctly.
When we walk through the parents, we must stop after the root, but
since it wasn't well initialized, its parent pointer was random.
Also the number of hits was random because uninitialized, hence it
was part of the callchain while the root doesn't contain anything.
This fixes segfaults and percentages followed by empty callchains
while running:

Currently symbol resolution does not work for 64-bit programs on architectures
that use function descriptors such as ppc64.
The problem is that a symbol doesn't point to a text address, it points to a
data area that contains (amongst other things) a pointer to the text address.
We look for a section called ".opd" which is the function descriptor area. To
create the full symbol table, when we see a symbol in the function descriptor
section we load the first pointer and use that as the text address.
