1d8aed840c . no more HZ, but use sys_hz() to get that value 
. memory maps in physical memory (for /dev/mem) with new vm interface
 . pci complete_bars() seems to be buggy behaviour sometimes
 . startup script opens its own stdout, stderr and stdin so init doesn't
   have to do it

f7992c94ec at_wini also needs a pci_reserve() for the pci compatability device, if 
present, for dma.

168d766f32 . pci driver now returns devices, even when they have been pci_reserve()d 
. pci_reserve() returns an error on devices that have already been reserved,
  instead of panic()ing; the pci_reserve() library call still panics,
  pci_reserve_ok() returns an int.
. this allows at_wini to use the instance value as intended, as all devices
  are seen, even reserved ones
. only devices actually used by at_wini are pci_reserve()d
. pci doesn't release devices based on argv[0], as at_wini both have the
  same name and multiple instances won't work together properly

1ff8616378 set 'w_testing' during w_identify(). this means 0-tolerance to 
timeouts, and an ATA_IDENTIFY timeout will cause the ATAPI_IDENTIFY
to be skipped, making the cd probe a lot faster.

c6f8154df0 use shorter ata timeout for identify commands when running from cd 
to shorten probe time.

8ea438ae93 Retired DEV_{READ,WRITE,GATHER,SCATTER,IOCTL} (safe versions *_S are to 
be used and drivers should never receieve these 'unsafe' variants
any more).

b01aff70d2 use servers/inet/mq.[ch] to queue messages using mq_queue() in 
libdriver.  at_wini now queues messages it can't handle it receives when
waiting for an interrupt. this way it can do receive(ANY) and timeouts
should be working again (were broken for VFS, as with the advent of VFS,
at_wini could get requests from a filesystem while it was waiting for an
interrupt - as a hack, the receive() was changed to receive(HARDWARE)).

Added mq.c to libdriver, and made libdriver an actual library that
drivers link with -L../libdriver -ldriver. (So adding files, if
necessary, is easier next time.)

1a7f7d6333 at_wini: removed RO_BIT misfeature, not used any more 
pm: fixed rebooting by making a copy of the monitor code from the user
    process. this is necessary because that process is dead by the time
    sys_abort() is called.

    also added more info to the "can't reply" panic.

f877da3aec endpoint migration for drivers. 
mostly renaming message field names to the new names.
