b012d72856 Add a test for origin tracking through large floating point arrays.

79c14a0983 Add comments giving an overview of the origin tracking implementation. 
Also, rename "ocache" to "ocacheL1" to be more consistent with the
comments and the rest of the otag cache code.

32a83b165a Dynamically allocate the origin tracking cache as needed (only for 
runs with --track-origins=yes), rather than having it statically
allocated.  This is important because the cache is large (100MB) and
soaking up 100MB of address space for a non-tracking run is not good.
Unfortunately this slows down the origin tracker by 1 to 2 %.

8c61ca1c09 Re-check complex and fragile bit-twiddling pertaining to indexing into 
the primary map on 64-bit systems.  Add extensive comments and
startup-time assertions.

As a result of this, fix two off-by-one errors in
MC_(helperc_MAKE_STACK_UNINIT) (unlikely to be of much significance,
but still ..).  No other errors were found.

0d5557aee9 Minor cleanups: 
* remove 'extern' in all the headers, as that is irrelevant and wastes
  horizontal space

* fix some 64-bit uncleanness in client(-defined) block handling

* remove unneeded #includes

4d1716321e Move the error management code for Memcheck into a new file, 
mc_errors.c, as it is relatively self contained.  This reduces the
size of mc_main.c by about 1350 lines.

a1289fb4ca Bump the core/tool iface version number, since the just-merged-in 
changes for Memcheck origin tracking change the interface (slightly).

3c25a48a0c Temporarily work around compilation failures caused by non-definition 
of __NR_timerfd, pending proper resolution.  See

4cae5c3ed5 Merge branches/OTRACK_BY_INSTRUMENTATION into the trunk. This adds 
support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.

This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output.  This
will be fixed.

The core-tool interface is slightly changed.  The version number for
the interface needs to be incremented.
