1b3a92639e Moved VG_(start_debugger) out of m_main.c into its own module,
m_debugger.  This removes the dependence of m_signals.c and m_errormgr.c
on m_main.c.  It required also moving VG_(clexecfd) out of m_main.c;  I put
it in m_libcproc.c which seemed like an ok-but-not-great choice.

577e69aafd Fix up the libc_freeres_wrapper code so that m_main depends on m_redir,
not the other way around.

e260572784 Move VG_(sanity_check_general) out of m_main.c into scheduler.c.
Removes the dependence of m_scheduler/ on m_main.c;  reduces the 
dependence of m_signals.c on m_main.c.

62fa883300 Move VG_(bbs_done) out of main and make it local in scheduler.c. This
removes the dependence of m_translate.c and m_libcassert.c on m_main.c.

f174930b23 Final commit for the initial modularisation pass:
- 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.

3ae4d1a0ab A cleanup of the redirection stuff.
- 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...
     [later...]

e3abdc62d5 Finished the modularisation of vg_mylibc.c, which meant it could be removed.

d13bacd9cd Modularised vg_main.c as m_main.c. Moved some stuff out of it to reduce the
number of files that depend on it, but there are still some which should be
removed in the future.
