* Add CONFIG_MICROWINDOWS_NANOX_NONETWORK which builds the Nano-X
client library and server in the linked-in (NONETWORK) mode, so
client applications are linked directly with the server and run in
the same task, requiring no network stack or socket at all
* Reorganize the source lists: the drawing sources (nxdraw, nxutil,
nxtransform, nxpaintnc) are shared by both modes, while the server
is built from srvnet.c in the network mode and srvnonet.c in the
NONETWORK mode
* Use MULTITHREAD_SERVER in the network mode so that several client
tasks can run at the same time in the flat build
* Let the examples/nanoxterm start the server task only in the
network mode (NONETWORK applications run the server inside main)

* Port the nxterm demo from Microwindows
* Starts the Nano-X server as a separate task before connecting
* Runs an NSH shell instance on a pseudo terminal in the spwaned child
instead of exec /bin/sh (no filesystem binaries in flat builds)
