Avoid loops in CCS graph.

- generalise the per-module initialisation stubs so that we use it
  in normal (non-profiled) code too.  The initialisation stubs are
  now called '__init_<module>' rather than '_reg<module>'.

- Register foreign exported functions as stable pointers in the
  initialisation code for the module.  This fixes the foreign export
  problems reported by several people.

- remove the concept of "module groups" from the profiling subsystem.

- change the profiling semantics slightly; it should be unnecessary
  to use '-caf-all' to get reasonable profiles now.

oops, need to define prof_file when DEBUGging too.

Remove duplicate prof_file variable.  Heap profiling should work again.

Fitst cut at XML-style profiling logs.  Time/allocation profiling only
for now, and the new flag '+RTS -px' enables the new log file format.

Fix for DEBUG && !PROFILING

Cost-centre heap profiling and symbol table heap profiling are now
merged into one file: ProfHeap.c.
