0333f21d8e - reverse order of transfer command and DMA initiation - fixes DMA problem
that some hardware had
 - clear DMA_ST_INT after DMA - fixes infinite number of interrupts 
   that some hardware had
 - initial ATAPI DMA implementation, doesn't actually increase performance
   on my test hardware so possibly not right yet, disabled by default

4dad30937b Removed macros that depend on NOTIFY_FROM from servers and drivers. They
determine the information defined by these macros from the m_source field of the
notify message.

89bf7bae27 - tty: only report unrecognized scancodes once; forget about
remembering the origin and cursor position as that feature didn't
   really work properly anyway
 - tty: map in video and font memory using a vm call, access it from C,
   thereby eliminating pesky weird segment calls and assembly to access it,
   and unbreaks loadfont (Roman Ignatov)
 - bios_wini: fix bios_wini by allocating a <1MB buffers for it
 - memory: preallocate ramdisk, makes it a bit faster (and doesn't
   fail halfway if you allocate a huge one)
 - floppy: use <1MB buffer
 - ramdisk proto: because of the 2x1 page reservations, binaries
   got a little fatter and didn't fit on the ramdisk any more.
   increase it.

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

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.
