Make contents a char* to avoid typecasts all over the place

* procfs.h (procfs_cleanup_contents_with_free,
  procfs_cleanup_contents_with_vm_deallocate, procfs_get_contents,
  struct procfs_ops): Change CONTENTS from a void pointer to a char one.
* dircat.c, netfs.c, process.c, procfs.c,
  procfs_dir.c, proclist.c, rootdir.c: Update.
