[PATCH] - add setbuffer/setlinebuf functions

[Gareth Pearce]

Hi

I noticed that these 2 functions were not part of the newlib library - even
though they are defined in the headers.
Attached is 2 patches one for a new file setbuffer.c in libc/stdio/ and the
other for modifications to the makefiles in that directory.

This is my first go at something like this - so it wouldnt supprise me if I
have something amiss, feel free to tell me what I need to do to correct
this, or if I am out of place trying to get this added.

If this goes in, I will submit another patch for the cygwin.din to export
these if that is needed.
