branch hereby becomes inactive. This currently breaks everything
except x86; fixes for amd64/ppc32 to follow.

- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.
- Managed to finally remove core.h and tool.h, double hurrah!
- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.
- Lots of little cleanups and changes related to the above.
- I even did a small amount of documentation updating.

- Renamed VG_INTERCEPT as VG_REPLACE_FUNCTION to make its purpose
clearer.
- Renamed VG_WRAPPER as VG_NOTIFY_ON_LOAD to make its purpose cleare.
Started calling that stuff "load notification".
- Moved various things into m_redir.c, a much more sensible place for
them. This reduced the number of exported functions overall. Renamed
intercept_demangle() as Z_decode() as part of this.
- Improved the documentation of this stuff, especially in
pub_core_redir.c.
- Got --run-libc-freeres=yes working again. It was doing nothing.
- Renamed vg_inject.so as vg_preload_core.so to match
vg_preload_<tool>.so
- Renamed vg_intercept.c as vg_preloaded.c. (I kept the "vg_" prefix
because this filename can appear in stack traces, so the "vg_" is a
useful hint for users that it belongs to Valgrind.)
- Removed all the Memcheck-specific calls to add_redirect_sym_to_sym()
from VG_(setup_redirect_table)(), instead using VG_REPLACE_FUNCTION in
mac_replace_strmem.c, just like vg_replace_malloc.c. This is the
right way to do it. This required moving some of
coregrind/pub_core_redir.h into the newly added
include/pub_tool_redir.h. add_redirect_sym_to_sym() is no longer
used...
- Now only handing off symbols to m_redir for inspection/decoding after
they have been deemed to be interesting by the symbol table reader.
- Factored out commonality between the add_redirect_*_to_* functions
into add_redirect_X_to_X().
- Added "Zh", meaning '-' ('h' for "hyphen"), to the Z-decoding scheme,
to handle sonames like "ld-linux-x86-64.so.2".
- Added a FAQ explaining the newly found issue of glibc aliasing
sometimes causing the wrong function name to appear in stack traces.
- Added a new regtest strchr.c. It's possible this will fail on some
platforms. If so, an alternative output file can be provided, but
I'd like to see it in practice first.
It's possible that there will be minor breakage on other
platforms/setups, but it should be minimal and easily fixable.
Plus some ordinary cleanups in symtab.c:
- Removed the old optimisation from VG_(addStr)() whereby it kept track
of the previous 5 added strings and avoiding duplicating any of them.
Turns out it was barely having any effect any more, and just
complicated things.
- Made read_symtab() more readable, by introducing a new variable
"sym_name" and introducing the auxiliary function
is_symbol_interesting().
- renamed the module variable 'segInfo' as 'segInfo_list' to make it
more obvious it's a module variable and not just some ordinary local
variable (which was an easy mistake to make).

XXX: [later] remove add_redirect_sym_to_sym, and everything related to
X_to_sym? (ie. only need X_to_addr)
XXX: better function names? all those 'resolved' names...

needs to #include pub_core_mallocfree.h. As a result, we need
to #include it explicitly everywhere else.

malloc/free implementation, and m_replacemalloc with the stuff for the tools
that replace malloc with their own version. Previously these two areas of
functionality were mixed up somewhat.
