Contribution description
This adds a function to check if all bytes in a buffer are set to a certain value.
Currently only gnrc_pktbuf_static` makes use of this, but I've used something similar in other places, often open-coded - so let's add it in a common place instead.
Testing procedure
A new unit test has been added.
