* Fix rare failure caused when end pointer is at end of buffer memory
and a call to ringbuf_get() is made that reads all of the data in the
buffer; start pointer was advanced past end pointer, causing some
special handling to be skipped
* Fix ringbuf_peek() moving start pointer
* Fix use after free
* Remove extraneous assignment
* Update relevant tests

Peek functionality for ring buffers and associated tests.
Also:
* Slight optimization to avoid 0-byte memcpy() by changing > to >=
* Add rv checks for some ringbuf_[put|get] calls that were missing them
in the test
