Chris Tate 9632906b4d Take from a Readable's buffered queue by moving its head index ...

Taking the head entry of a Readable's buffer moved every remaining entry
down one slot, so draining a queue of n buffered chunks cost O(n²). The
buffer now keeps the index of its first entry: a take advances it, a push
at the tail moves the entries down only when at least half the slots are
free at the front (and grows otherwise), and unshift takes a freed front
slot when there is one. The drop, trace and boxing loops walk the entries
from that index.

The stream-buffered-drain runtime workload buffers 200,000 objects and
100,000 Buffers before draining them; corpus 8533 covers reads across
entries, unshift into a freed slot and onto a part-read head, setEncoding
after takes, and object-mode takes, unshifts and pushes.
