fuse: split out filesystem part of request sending

Create a new source file: req.c and add the request sending entry
functions:

__fuse_simple_request()
fuse_simple_background()
fuse_simple_no

fuse: split out filesystem part of request sending

Create a new source file: req.c and add the request sending entry
functions:

__fuse_simple_request()
fuse_simple_background()
fuse_simple_notify_reply()

Introduce transport layer sending functions that are called by the
respective fs layer function:

fuse_chan_send()
fuse_chan_send_bg()
fuse_chan_send_notify_reply()

Move calculation of request header fields uid, gid and pid from
fuse_get_req() and fuse_force_creads() to a new helper: fuse_fill_creds().

These fileds are now passed to the transport layer via struct fuse_args.
