The patch re-factors libgcov.c to make it better modulelized.
It contains two pieces of work:
1. break gcov_exit() into the following structure:
   gcov_exit()
      --> gcov_exit_compute_summary()
      --> allocate_filename_struct()
          for gi_ptr in gcov_list
            --> gcov_exit_dump_gcov()
                   --> gcov_exit_open_gcda_file()
                   --> gcov_exit_merge_gcda ()
                   --> gcov_exit_merge_summary ()
                   --> gcov_exit_write_gcda ()
2. split libgcov.c into the following files:
     libgcov-profiler.c
     libgcov-merge.c
     libgcov-interface.c
     libgcov-driver.c
       libgcov-driver-system.c (source included into libgcov-driver.c)
