b5e3e6d18c Two 'dynamic driver' features in FS:
.  When drivers disappear that have pending select()s, wake up
   those user processes with EAGAIN so that they can retry their
   select() and won't hang forever on it.
.  When drivers re-appear and are mapped into the dmap, run through
   the list of mounted filesystems and re-dev_open() every one (for
   partition tables and such). This can't happen before the driver
   has exec()ced itself, so processes that have fork()ed but not
   exec()ced yet are marked as DMAP_BABY in the dmap table if they
   are dmapped before they are execced. If that happens, the above
   procedure happens after the exec(). If the exec() happens before
   the dmapping, it (the dev_open()ing) happens right away.

6e8f484b3b . added cd-probe logic; tries to find the right root filesystem
if the boot monitor parameter is set. it also sets a boot monitor
  parameter (by talking to the PM) so userland knows it.
. ramdisk copy code made slightly smarter
. various select() prettifications (work in progress)

42050e39f8 kernel and servers send diagnostic messages to IS; IS sends them to TTY
and the new log driver if enabled.

new usyslogd is started from /usr/etc/rc. New device created by
MAKEDEV.sh. /var/log created by etc/mtree/minix.tree (on root for
now). Made select() slightly more generic, with less code duplication.

9664ba0c4f Started select() implementation.
Added interface to select() for pipes (also named pipes), and select()
stubs for regular files.

Added timer library in FS that select() is the first customer of.


This is unfinished, but committed anyway to get a new release out to
Al and testers.

e44e9ad261 small compile fixes; initial select() stubs; release.sh script doesn't
need /tmp any more since 16MB root device; increase to 3.0.5 to make new
CD with working FXP driver. (not tagged 3.0.5 yet as at driver bios-copy
workaround hasn't been done.)
