toybox: toys/pending/arp.c annotate

annotate toys/pending/arp.c @ 1539:3e85af1f7e22 draft

First batch of sed tests. Only good for TEST_HOST=1 at the moment because the test infrastructure itself depends on sed, so if an unfinished sed is in the $PATH it goes boing. But hey, corner cases! I have... more.
