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.

printf() by kernel and servers now send messages to an array of processes, OUTPUT_PROCS_ARRAY in <minix/config.h>, in that order, terminated by NONE. log no longer forwards messages to tty itself. This leads to less funny loops and more robust debug-message handling. Also the list of processes receiving messages can easily be changed around or disabled by editing the array (e.g. disable it by changing the array to { NONE }.).

A new panic that makes processes exit with PM knowing about it, instead of sys_exit, so that PM functions (e.g. findproc) keep working properly, and RS finds out about process deaths.
