strchr() and strrchr() are already present in the kernel, but with less

popular names. Hence:

- comment current index() and rindex() functions, as these serve the same
  functionality as, respectively, strchr() and strrchr() from userland;
- add inlined version of strchr() and strrchr(), as we tend to use them more
  often;
- remove str[r]chr() definitions from ZFS code;
