Bill Somerville f416a52def Make Fortran profiling timer function a callback with a default null implementation
Groundwork for calling the decoders directly from C/C++ threads.

To  access   the  timer   module  timer_module   must  now   be  used.
Instrumented code need  only use the module function  'timer' which is
now a  procedure pointer that  is guaranteed to be  associated (unless
null()  is assigned  to it,  which should  not be  done). The  default
behaviour of 'timer' is to do nothing.

If a  Fortran program  wishes to  profile code it  should now  use the
timer_impl module  which contains a default  timer implementation. The
main program should call 'init_timer([filename])' before using 'timer'
or     calling     routines     that     are     instrumented.      If
'init_timer([filename])'.  If it is called  then an optional file name
may  be  provided  with  'timer.out'  being used  as  a  default.  The
procedure 'fini_timer()' may be called to close the file.

The default  timer implementation is  thread safe if used  with OpenMP
multi-threaded code  so long as  the OpenMP  thread team is  given the
copyin(/timer_private/) attribute  for correct operation.   The common
block /timer_private/ should  be included for OpenMP  use by including
the file 'timer_common.inc'.

The module 'lib/timer_C_wrapper.f90' provides  a Fortran wrapper along
with 'init' and 'fini' subroutines  which allow a C/C++ application to
call timer instrumented  Fortran code and for it  to receive callbacks
of 'timer()' subroutine invocations.  No C/C++ timer implementation is
provided at this stage.
