This commit (temporarily) leaves MINIX 3 without a TCP/IP service.
Thanks go out to Philip Homburg for providing this TCP/IP stack in the
first place. It has served MINIX well for a long time.

This patch adds the implementation of the BSD socket system calls
which have been introduced in an earlier patch. At the same time, it
adds support for communication with socket drivers, using a new
"socket device" (SDEV_) protocol. These two parts, implemented in
socket.c and sdev.c respectively, form the upper and lower halves of
the new BSD socket support in VFS. New mapping functionality for
socket domains and drivers is added as well, implemented in smap.c.
The rest of the changes mainly facilitate the separation of character
and socket driver calls, and do not make any fundamental alterations.
For example, while this patch changes VFS's select.c rather heavily,
the new select logic for socket drivers is the exact same as for
character drivers; the changes mainly separate the driver type
specific parts from the generic select logic further than before.

All functions prefixed with bdev_ are moved into bdev.c, and those
prefixed with cdev_ are now in cdev.c. The code in both files are
converted to KNF. The little (IOCTL-related) code left in device.c
is also cleaned up but should probably be moved into other existing
source files. This is left to a future patch. In general, VFS is
long overdue for a source code rebalancing, and the patch here is
only a step in the right direction.
