As we no longer have the FILE type, we need to buffer our reading and
writing so that we don't have to make so many syscalls. The API is nice
so that we can buffer other readers. We will update it so that it eats
io·Readers/io·Writers.

We use weak linking to ensure we clean up at exit time correctly. If
libc is linked, then we call our cleanup function by registering an
atexit callback with the library. If libc is not linked, we have a weak
symbol that results in a noop. Similarly, if we call rt·exit while
linked with libc, this immediately calls libc's exit (which will call
our cleanup as we registered it). If we are not linked to libc, exit()
is given as a weak link to a noop function.

I found the split to be arbitrary. Better to include the functionality
in the standard library. I also split the headers to allow for more
granular inclusion (but the library is still monolithic). The only
ugliness is the circular dependency introduced with libutf's generated
functions. We put explicit prereqs with the necessary object files
instead.
