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. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6320 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
