Implement --keep-stacktraces=alloc|free|alloc-and-free|alloc-then-free|none
The option --keep-stacktraces controls which stack trace(s) to keep for
malloc'd and/or free'd blocks. This can be used to obtain more information
for 'use after free' errors or to decrease Valgrind memory and/or cpu usage
by recording less information for heap blocks.
This fixes 312913 Dangling pointers error should also report the alloc
stack trace.

This commit subtly changes the meaning of the values obtained via the
stack unwind mechanism (the function VG_(record_ExeContext) et al),
clears up some associated kludges, and makes suppression matching work
more reliably.
Prior to this commit, a stack snapshot contained, at [0], the IP of
the relevant thread, and at all positions [1] and above, the return
addresses for the open calls.
When showing a snapshot to the user (in VG_(apply_StackTrace)), and
searching the stack for stack blocks (in VG_(get_data_description)), 1
is subtracted from positions [1] and above, so as to move these return
addresses back to the last byte of the calling instruction. This
subtraction is also done even in VG_(get_StackTrace_wrk) itself, in
order to make the stack unwinding work at all.
It turns out that suppression-vs-function-name matching requires the
same hack, and sometimes failed to match suppressions that should
match, because of this self-same problem.
So the commit changes the stack unwinder itself, so that entries [1]
and above point to the last byte of the call instruction, rather than
the return address. The associated kludges in VG_(apply_StackTrace)
and VG_(get_StackTrace_wrk) are removed, and suppression matching is
observed to work in a case where it failed before.

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.

Add a new method VG_(record_depth_1_ExeContext), a trivial derivative
of VG_(record_ExeContext), which just records the first stack frame
but does not attempt to unwind the (guest) stack. This is useful in
situations where we suspect unwinding the stack might cause a
segfault.
Use this in m_signals, when getting a backtrace following a guest
segfault.

Merge (from branches/THRCHECK) the following amd64-linux stack unwind
kludges^H^H^H^H^H^H^Henhancements:
r6802: For VG_(record_ExeContext) et al, add a new parameter
(first_ip_delta) which is added to the initial IP value before the
stack is unwound. A safe value to pass is zero, which causes the
existing behaviour to be unchanged. This is a kludge needed to work
around the incomplete amd64 stack unwind info in glibc-2.5's clone()
routine.
r7059: Add a last-ditch heuristic-hack to the amd64-linux stack
unwinder, which is used when all other methods fail. Seems like GDB
has something similar.

A modularisation + refactoring commit. vg_execontext.c has been split into
two halves: stacktrace.c, which deals with getting, traversing and printing
stack traces; and execontext.c, which deals with storing stack traces
permanently in a way that avoids duplicates, and comparing them.
One nice outcome: previously we were often creating ExeContexts, which live
forever, even when they were only needed temporarily. Ie. this was a memory
leak, which has been removed.
As part of this, new headers have been created, carved off core.h and
tool.h. Lots of function names have changed, too.
In Massif, I also changed a lot of "eip" names to "ip" to make them less
x86-specific.
