The main idea is to make DatagramChannel and *SocketChannel behave in
a way that more closely matches the standard, e.g. allow binding
sockets to addresses without necessarily listening on those addresses
and accept null addresses where appropriate. It also avoids multiple
redundant DNS lookups.
This commit also implements CharBuffer and BindException, and adds the
Readable interface.
We do not really support regular expressions yet, but we do support
trivial patterns including ones with escaped characters. Let's make sure
that that works as advertised.

We were incorrectly returning an empty array when the input was empty,
whereas we ought to return an array containing a single empty string.
When the pattern to match was empty, we went into a loop to create an
infinite list of empty strings, only to crash once we've run out of
memory. This commit addresses both problems.
