Ints in buffers are 32 bit
...
...for consistency with Idris 1 (probably to be revisited later). So,
when working via the scheme primitives, we need to read/write 32 bits.

Some Data.Buffer bits

Need to know length of strings in bytes sometimes, not just characters,
to check we have enough space.
Also add copyData

Reading/writing buffers can fail
...
So, make them return and Either and wrap the scheme definitions in an
exception handler that returns an error code on failure

Experimenting with a new FFI
...
Functions can be declared as %foreign with a list of calling
conventions, which a backend will work through until it finds one it can
understand. Currently implemented only in Chez backend. If this works
out, I'll implement it for Racket too, and remove the old primitive
functions.
There's a bit more boiler plate here than before, but it has the benefit
of being more extensible and portable between different back ends.
Some examples, pending proper documentation:
%foreign "C:puts,libc" "scheme:display"
putline : String -> PrimIO ()
%foreign "C:exp, libm.so.6, math.h"
fexp : Double -> Double
%foreign "C:initscr, ncurses_glue.so, ncurses.h"
prim_initscr : PrimIO ()

A bit more library support, for Chapter 9
...
Also a tweak to errors when compiling to scheme, so that it properly
reports an error then quits if it's supposed to crash.
