96b2ce64c0 Helgrind's event-map garbage collector hammers VG_(OSetGen_Next).

468ca56d5d event_map_maybe_GC: use a flat array when computing the distribution 
(counts) of generation numbers in the oldrefTree, instead of using a
WordFM as an associative array.  This significantly accelerates the
event map garbage collector.

36ca6df95a Re-set constraints in 'consistent' style after a race is detected, 
instead of the more aggressive setting, which appeared to cause a
large number of extra race reports.

9398b50c4a Don't put raced-on locations in an (E)rror state; instead leave them 
in a (C)onstraint state.  The former approach can cause races to be
missed.  Also, update state machine slightly following re-analysis
thereof.

330495b563 * Update Qt4 interceptors and add, as comments, findings of analysis 
of Qt4 threading functions.

* Add a bunch of replacements for strlen etc, to avoid races from
  optimised glibc versions that overread memory.  Copied directly from
  memcheck/mc_replace_strmem.c.

c9b2f74417 event_map_maybe_GC: handle corner case that was previously simply 
asserted on: if all the entries in the event map are in the same
generation, then we have no LRU information at all with which to
decide which entries to discard.  So in this case throw away half of
them randomly -- there's nothing better we can do.

eb5e457e3e Move the conflicting accesses in each thread earlier, so that pure h-b

(Not really sure what's going on here, but DRD and Helgrind behave
identically, so I'm not too concerned.)

cf588ba40d When trying to establish whether or not debuginfo should be read from 
a file, first the mapping permissions _before_ peering at the file's
header, rather than afterwards.  This changes the logic to behave more
like it does in 3.3.x.  Fixes #164669, although really it is all still
rather fragile.  The bug report,
http://bugs.kde.org/show_bug.cgi?id=164669, contains a detailed
explanation.
