#24 please feature divide about WITH_NOIO

[moolbob]

WITH_NOIO feature is contain file I/O and socket I/O.

I was porting gSOAP source to REX OS(Embedded OS).
REX OS environment not contain socket I/O.

can you divide feature WITH_NOIO?

#define WITH_NOIO
->
#define WITH_NO_FILE_IO
#define WITH_NO_SOCKET_IO
(it's just simple idea)
