Norman Feske ff2176a586 vfs,libc: support write fds in select 
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.

Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.
