io: more hot-rodding for #376
...
* Change the interface of read-into to return a slice and an eof boolean separately so the compiler can optimize the slice.
* Add an each-stream-block-slice combinator that behaves like each-block but reuses a preallocated buffer for every iteration.
* Pull some strings in the stream-read-into implementation to further improve type propagation and bounds check elimination.

io:read: don't resize output buffer if unnecessary
...
Even with a short-circuit test in the VM primitives, resize still has an overly high runtime cost in tight loops. For #376 .

io: stream-contents, -seekable?, -length generics
...
stream-contents is extremely slow on decoder streams when implemented with each-block, and it can be implemented very quickly for streams of known length using stream-read-unsafe. Make it generic and provide some off-the-shelf implementations using each-block, a read1 loop, or length + read-unsafe. Provide new stream-seekable? and stream-length generics that can be implemented by stream implementations that know their size.

io: non-copying each-block and contents variants
...
each-(stream-)block* is like each-block but takes a buffer object and reads into it repeatedly. (stream-)contents* determines the stream length then does a single stream-read-unsafe into a preallocated buffers. Both functions currently only work for byte-arrays (and contents* only for seekable streams), so they can't replace the non-starred versions completely just yet.
