779bbb61c6 Add support for reading Windows PDB debug info (symbols and line
numbers) when Valgrind is running Wine.  Modified version of a
patch by John Reiser (vgsvn+wine-load-pdb-debuginfo.patch) with
extensions to read a second format of line number tables.

Wine uses a new client request, VG_USERREQ__LOAD_PDB_DEBUGINFO,
to tell Valgrind when to read PDB info.  Wine's implementation
of module loading is vastly different from that used by
ld-linux.so, and it is too difficult to recognize what is going
on just by observing the calls to mmap and mprotect.

01a6838e61 Cleaned up the demangling mess:
- Now more clearly distinguishing between C++-demangling, Z-demangling, and
  below-main renaming, particularly in 'get_sym_name'.
  
- --demangle=no no longer prevents Z-demangling, which makes more sense,
  although it's unlikely to affect anyone.

- Broke the circular dependency between m_demangle and m_debuginfo by moving
  below-main renaming into m_debuginfo.

- Renamed some get_fnname_* functions to make their effect clearer, and
  improved their comments.

35c28b721f Merge Helgrind from branches/YARD into the trunk. Also includes some
minor changes to make stack unwinding on amd64-linux approximately
twice as fast as it was before.

335992d8fc Merge all remaining changes from branches/PTRCHECK. These are some
relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.

The majority of the merged changes were committed into
branches/PTRCHECK as the following revs: 8591 8595 8598 8599 8601 and
8161.

a9bbc3690b Fix an all-platforms bug introduced by the recent overhaul of function
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.

f9a9e03c7a Merge in function wrapping support from the FNWRAP branch. That
branch hereby becomes inactive.  This currently breaks everything
except x86; fixes for amd64/ppc32 to follow.

cc8ccbbfb4 This commit merges in changes from branches/ASPACEM (specifically,
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.

e7aa6b03de Made m_debuginfo not depend on m_aspacemgr, breaking the direct circular
dependence between them.  (There's still an indirect one via m_libcmman.)

As a result, I was able to move the Segment type declaration into
pub_core_aspacemgr.h, which is a much better spot.  I was also able to
remove a couple of #includes.
