Summary: Implement lazy read for sockets

Initial Comment:
When a socket is transformed into a file object using
the makefile() method, the resulting object read()
behaviour requires that read(N)
returns N characters or that the end of stream be reached.

This causes problems with XML parsers which call
read(BufferSize) to
get "something", not necessarily a full buffer.

The following patch adds a "lazy" attribute to each
socket._fileobject
instance, the default being set to False in order to be
backward
compatible. If this attribute is set to True, read(N)
will return at least
one character unless the end of stream is reached, and
no more than
N characters.
