David van Moolenbroek 9ba65d2ea8 This patch switches the MINIX3 ethernet driver stack from a port-based
model to an instance-based model. Each ethernet driver instance is now
responsible for exactly one network interface card. The port field in
/etc/inet.conf now acts as an instance field instead.

This patch also updates the data link protocol. This update:
- eliminates the concept of ports entirely;
- eliminates DL_GETNAME entirely;
- standardizes on using m_source for IPC and DL_ENDPT for safecopies;
- removes error codes from TASK/STAT replies, as they were unused;
- removes a number of other old or unused fields;
- names and renames a few other fields.

All ethernet drivers have been changed to:
- conform to the new protocol, and exactly that;
- take on an instance number based on a given "instance" argument;
- skip that number of PCI devices in probe iterations;
- use config tables and environment variables based on that number;
- no longer be limited to a predefined maximum of cards in any way;
- get rid of any leftover non-safecopy support and other ancient junk;
- have a correct banner protocol figure, or none at all.

Other changes:
* Inet.conf is now taken to be line-based, and supports #-comments.
  No existing installations are expected to be affected by this.
* A new, select-based asynchio library replaces the old one.
  Kindly contributed by Kees J. Bot.
* Inet now supports use of select() on IP devices.
  Combined, the last two changes together speed up dhcpd
  considerably in the presence of multiple interfaces.
* A small bug has been fixed in nonamed.

/usr/src/etc/usr/rc updated: copy it (or merge it) to /usr/etc/rc.
/etc/inet.conf is now line-based; if you have hand-edited this file
before, then make sure that you do not have configurations in there
that span multiple lines.

/etc/drivers.conf has been renamed to /etc/system.conf.
user "service" has been added to password file /etc/passwd.

OSS requires an improved make to be compiled; run "make install"
in /usr/src/commands/make before running "make world".
20070212 (r2751):
mkfs needs more memory to make an image; chmem it or do
# touch mkfs.c ; make /usr/bin/mkfs
in /usr/src/commands/simple.
20070118:
drivers.conf has been updated to include an ACL for mfs. it has
to be installed before rebooting after an update of the mount command.
20061222:
The archictecture-dependent/-independent split needs ARCH=<arch>
in /etc/make.conf, included by some Makefiles and sourced by
some shell scripts. To install it, type 'make install' in
src/etc, or simply copy the file over.
20061222:
Install binaries in the right order because the new readdir
implementation and the new mount program are incompatible
with older kernels and the new kernels require the new mount.
# cd /usr/src
# make includes
# make libraries
# make cmds
# make depend
# cd /usr/src/tools
# make hdboot
# make install
# cd ..
# make install
Installing fails for boot. Reboot the system
# reboot -x 'unset image; boot'
Now install everything
# cd /usr/src
# make install

You need flex in your $PATH, which has become part of the base
system. This needs bigger binaries.
If you don't have flex yet, you can compile it first by doing:
# cp /usr/src/etc/binary_sizes* /etc
# binsizes big
# cd /usr/src/commands/flex-2.5.4
# sh build
