Basically these functions are implemented the same way as the
corresponding functions in the strings package.  Test functions
are implemented for IndexRune and FieldsFunc.

Additionally two typos are fixed in packages bytes and strings.

Plays more nicely with ELF ABI C code.
In particular, our signal handlers will no longer crash
when a signal arrives during execution of a cgo C call.
