2fe79d0b76 Implement AcpiOsStall, AcpiOsSleep, AcpiOsGetTimer
- change AcpiOsRemoveInterruptHandler() to print a warning
  instead of panic.

- we do the same in AcpiOsInstallInterruptHandler().

51de979ed9 fix for checking CLEAN-ness of ramdisk image
. pre-cleanflag ("old") mkfs generates without CLEAN flag,
	  causing boot not working because imgrd disappears after 1st
	  close
	. fixed sanity check for this situation
	. disable imgrd disappearing in memory driver so
	  readonly mount succeeds in case it happens anyway

59ff5cbd87 mfs: clean flag
. also implement now-possible fsck -p option
    	. allows unconditional fsck -p invocation at startup,
    	  only checking each filesystem if not marked clean
    	. mounting unclean is allowed but is forced readonly
    	. updating the superblock while mounted is now not
    	  allowed by mfs - must be done (e.g. by fsck.mfs)
    	  on an unmounted fs
	. clean flag is unset by mfs on mounting, and set by
	  mfs on clean unmounting (if clean flag was set at
	  mount time)

71533c8a83 ACPI - fixed initialization of pci briges irqtable
- if no IRQ table is found, we report that ACPI cannot map IRQ
  correctly

- fixes mapping of IRQs in KVM because in this case we just fall
  through and use the IRQ configured by BIOS. PCI still reports
  that it failed to use ACPI. It is a hint if things go wrong.

e7db2d3588 Add fbd -- Faulty Block Device driver
This driver can be loaded as an overlay on top of a real block
device, and can then be used to generate block-level failures for
certain transfer requests. Specifically, a rule-based system allows
the user to introduce (overt and silent) data corruption and errors.

It exposes itself through /dev/fbd, and a file system can be mounted
on top of it. The new fbdctl(8) tool can be used to control the
driver; see ``man fbdctl'' for details. It also comes with a test
set, located in test/fbdtest.

4005bba437 libblockdriver: clear IPC only on stateful restart
This removes a race condition when the block driver performs a
complete restart after a crash (the new default). If any user of
the driver finds out its new endpoint and sends a request to the
new driver instance before this instance has had the chance to
initialize, then its initialization would clear all IPC state and
thereby erroneously cancel the incoming request. Clearing IPC
state is only desired upon a stateful restart (where the driver's
endpoint is retained). This information is now passed to and used
by libblockdriver accordingly.

67c012b3fc printer: perform probe on startup
This stops the printer driver from hanging the entire system when
/dev/lp is opened on systems that do not have a parallel port. With
this change, the printer driver shuts down immediately after loading
on such systems.

e2758c6759 libblockdriver: allow for not handling partitions

driver, which implies it wants the library to handle getting and

b4d909d415 Split block/character protocols and libdriver
This patch separates the character and block driver communication
protocols. The old character protocol remains the same, but a new
block protocol is introduced. The libdriver library is replaced by
two new libraries: libchardriver and libblockdriver. Their exposed
API, and drivers that use them, have been updated accordingly.
Together, libbdev and libblockdriver now completely abstract away
the message format used by the block protocol. As the memory driver
is both a character and a block device driver, it now implements its
own message loop.

The most important semantic change made to the block protocol is that
it is no longer possible to return both partial results and an error
for a single transfer. This simplifies the interaction between the
caller and the driver, as the I/O vector no longer needs to be copied
back. Also, drivers are now no longer supposed to decide based on the
layout of the I/O vector when a transfer should be cut short. Put
simply, transfers are now supposed to either succeed completely, or
result in an error.

After this patch, the state of the various pieces is as follows:
- block protocol: stable
- libbdev API: stable for synchronous communication
- libblockdriver API: needs slight revision (the drvlib/partition API
  in particular; the threading API will also change shortly)
- character protocol: needs cleanup
- libchardriver API: needs cleanup accordingly
- driver restarts: largely unsupported until endpoint changes are
  reintroduced

As a side effect, this patch eliminates several bugs, hacks, and gcc
-Wall and -W warnings all over the place. It probably introduces a
few new ones, too.

Update warning: this patch changes the protocol between MFS and disk
drivers, so in order to use old/new images, the MFS from the ramdisk
must be used to mount all file systems.

ff542f0b27 atl2: prevent compiler memory access misordering
While no problems have been observed in practice yet, modern compilers
may reorder memory access operations, and that could lead to problems
with memory-mapped I/O typically done by drivers. This patch prevents
any potentially problematic reordering by the compiler in the ATL2
driver.

In addition, this patch removes a number of gcc/clang warnings.

e1d867b686 ahci/libdriver: multithreading support
This patch adds support for executing multiple concurrent requests on
different devices on the same AHCI controller. The libdriver library
has been extended to include a generic multithreading interface, and
the AHCI driver has been extended to make use of this interface.

The original version of this code has been written by Arne Welzel.

02081e4b62 rename mmap() and munmap()
. it's a good extra interface to have but doesn't
	  meet standardised functionality
	. applications (in pkgsrc) find it and expect
	  full functionality the minix mmap doesn't offter
	. on the whole probably better to hide these functions
	  (mmap and friends) until they are grown up; the base system
	  can use the new minix_* names
