kludge and may be replaced in future by something cleaner. See
extensive comment addition for the whole sorry tale.

Changes to support XCOFF:
- allow modules to have 'member names' as well as file names. A member
name is a "foo.o" name inside a "bar.a"; necessary as AIX
keeps all its dynamic libraries in .a files.
- rename the type RiLoc to DiLoc (this holds a line number indication).
No idea why it was called RiLoc in the first place.
- trace changes in type SysRes
- implement VG_(di_aix5_notify_segchange)

interface, except for the syscall numbers, into that. Mostly this
means moving include/vki-*.h to include/vki/vki-*.h.
include/pub_tool_basics.h previously dragged in the entire kernel
interface. I've done away with that, so that modules which need to
see the kernel interface now have to include pub_{core,tool}_vki.h
explicitly. This is why there are many modified .c files -- they have
all acquired an extra #include line.
This certainly breaks all platforms except x86. Will fix shortly.

rid of complaints from the CFA reader. Why didn't Red Hat push this
patch upstream? I don't know.

Dwarf, which is a (fully documented) Dwarf3 variant in which some
32-bit fields are expanded to 64 bits. Presumably this is useful for
those vast hordes of folks who regularly build executables or shared
objects more than 4GB long. For whatever reason, IBM's xlc/xlC/xlf
insist on generating 64-bit Dwarf when compiling even hello-world size
programs for ppc64-linux.

interception and wrapping. This was causing failures matching
function names in suppressions to function names in backtraces when
the latter names were Z-encoded (eg malloc), which typically caused
all leak suppressions to fail because they contain names such as
malloc, which are Z-encoded.

many shared objects, finding the relevant CFI information for stack
unwinding becomes a significant performance overhead. This change
slowly rearranges the SegInfo list to bring more popular entries to
the front during CFI lookup. This reduces the startup time of
konqueror on memcheck on amd64 from 124 to 110 seconds.

changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.
