Julian Seward 1a2c48a114 A major overhaul of how malloc/free intercepts are done. The general ...

idea is the same -- write functions with special names encoding
sonames and fn names, and have the redir mechanism notice them.
However the way the functions are generated is significantly changed:

* The name mangling scheme has been replaced with one which is just about
  simple enough not to need a preprocessing phase.  Hence
  vg_replace_malloc.c.base is replaced by vg_replace_malloc.c, and
  the preprocessor disappears.  The demangler in vg_symtab2.c changes
  accordingly.

* Kill off the horrendous LIBALIAS macro.  In return we have to
  enumerate all the redirections longhand, but this is not a big deal.

* Remove use of the GNUisms "attribute alias" and "attribute
  protected".

* Remove the hardwired assumption that any C++ new/new[]/etc symbols
  we might want to intercept are mangled in GNU style.

* Add more comments.
