80846c4a79 kernel ipc debug: various fixes
. add receive hooks in the kernel to print asynchronously
	  delivered messages
	. do not rely on MF_REPLY_PEND to decide between calls and errors,
	  as that isn't reliable for asynchronous messages; try both instead
	. add _sendcall() that extract-mfield.sh can then reliably recognize
	  the fields for messages that are sent with just send()
	. add DEBUG_DUMPIPC_NAMES to restrict printed messages to
	  from/to given process names

037aeb5a13 arm:rs232 fix.
The kernel API for requesting interrupts and the associated callback
have a somewhat strange behaviour. Requesting an interrupts is done
by calling sys_irqsetpolicy using an interrupt and a given id. This
id can be modified by the sys_irqsetpolicy and must be used for
subsequent calls to sys_irqenable/sys_irqdisable. However upon an
incoming call from the kernel NOTIFY_ARG contains the original value
encoded in a set e.g. if  1 << id == true the interrupt was raised.

e67fc5771d libc: add clock_getres()/clock_gettime() system calls.
In order to make it more clear that ticks should be used for timers
and realtime should be used for timestamps / displaying the date/time,
getuptime() was renamed to getticks() and getuptime2() was renamed to
getuptime().

Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2()
have been updated. In instances where a realtime was calculated, the
calculation was changed to use realtime.

System calls clock_getres() and clock_gettime() were added to PM/libc.

5acaa0814f kernel, ramdisk: some boot unification
To use the new SD building script, Linux has to be configured with
loop.max_part=15 on the command line (or set at module load time)
to make the loopback device see the partitions.

This commit removes a lot of differences between the ARM and x86
boot ramdisk and rc scripts. It changes the ARM build from running
from ramdisk to requiring a full filesystem on the SD image and
booting into it.

	. ramdisk: remove some arm-only utilities only used for running
	  from the shell
	. remove ARM-only rc.arm, proto.arm.small, ttys and mylogin.sh
	  boot-time ramdisk files
	. change kernel to add "arch" variable so userland knows what
	  we're running on from sysenv
	. make ARM use the regular ramdisk rc file, changed to distinguish
	  i386-only and ARM-only drivers; requires rootdevname to be set
	. change /etc/rc and /usr/etc/rc to start i386-only drivers only on
	  i386 systems
	. change the kernel/arm to have a special case for the memory
	  driver to load it higher so it can be bigger
	. add uEnv.txt, cmdline.txt and a for now highly linux-dependent
	  SD preparation script arm_sdimage.sh to the git repository in
	  releasetools/

8f3fbf7cc1 Cleanup: Remove minix.bootprog.mk
The build system distinction between "bootprog" and "service" is
meaningless as boot programs are standard services.

As minix.service.mk simply imports minix.bootprog.mk, reduce confusion
by removing minix.bootprog.mk and placing the rules in minix.service.mk.

ba49a155b5 fb: introduce framebuffer support to Minix
This patch introduces a framebuffer to Minix. It's written for the ARM
port of Minix, but has an architectural split that separates the
hardware dependent part from the non-hardware dependent part. Futhermore,
this driver was developed using a screen that has a native resolution of
1024x600 pixels and having lack of support for obtaining EDID from the
screen. Consequently, it uses a hardcoded resolution of 1024x600.

The driver uses an interface based on the Linux ioctl API, but supports
only a very limited subset.

All cards in this family (RTL8101E, RTL8102E, RTL8103E, RTL8105E,
possibly others) should be recognized based on the added PCI ID.
The hardware version number of the RTL8105E has been added only to
serve as an example of a card that does not require modification of
certain undocumented registers.

9d89e72a5c ahci: more robustness against flaky devices
- if supported, override BSY/DRQ flags and start the port anyway if it
  times out with DET=3h status during device detection;
- no longer rely on the device signature to be set; unless a valid
  signature is obtained, try both ATA and ATAPI device identification.

eb89b33d39 ahci: device detection rewrite
- do not start a port before the BSY and DRQ flags have been cleared;
  as such, poll on device status rather than signature availability.
- change "ahci_sig_timeout" to "ahci_device_timeout" variable setting
  accordingly; this variable determines the polling duration before a
  newly attached device is given up on, and uses 30 seconds as default;
- use port connect changes (PCS/X/DET->1h) to kick off polling for an
  attached device; detachment is still detected by means of PhyRdy
  status changes (PRCS/N/DET<->3h).

23b12e29a2 ahci: rewrite timeout initialization code
- the "ahci_sig_timeout" variable now denotes the entire checking
  period, and the delay between checks has been hardcoded; what was
  previously "ahci_sig_checks" is now computed from those two;
- timeout values are no longer used for both millisecond and clock
  tick values, and better typed;
- the computation of timeouts is no longer off by half a second.
