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.

kernel: rename realtime to monotonic, add realtime
Old realtime was used for both timers (where an accurate count of
all ticks is needed) and the system time. In order to implement
adjtime(2), these duties must be separated as changing the time
of day by a small amount shouldn't affect timers in any way nor
should it change the boot time.
Following the naming of the clocks used by clock_gettime(2). The
clock named 'realtime' will represent the best guess at the
current wall clock time, and the clock named 'monotonic' will
represent the absolute time the system has been running.
Use monotonic for timers in kernel and in drivers. Use realtime
for determining time of day, dates, etc.
This commit simply renames realtime to monotonic and adds a new
tick counter named realtime. There are no functional changes in
this commit. It just lays the foundation for future work.

Install default users directly
Install /home/ast and /home/bin as part of the system build procedure,

UDS: terminate canonical path string
When you provided a string with junk after the terminating nul to a
UNIX domain socket and used bind(2), the canonical path function would
not properly terminate the new string. This caused VFS to return
ENAMETOOLONG on an otherwise valid path name.
* Use the same output directory as was previously the standard.
* Add copying of uEnv and cmdline to the obj directory to allow booting from tftp.
* No longer start qemu at the end of the process.

Let the build system manage compilation flags
Do not hardcode warning and optimisation flags, otherwise the
main options (i.e. DBG, CPPFLAGS) will not work as expected.
You can still provide specific default by using DBG?=<value>.
Doing so leaves the opportunity to override the setting from the
commandline, while the default value from the build system is
then ignored for that particular package.
When crosscompiling, and using build.sh, adding -V DBG=<value> has
this same effect as make DBG=<value>.

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

. 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/

Select(2)ing on UNIX domain sockets was not working properly because

it should return an error when the other end closed the socket.

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.
Previously, installboot would require that the given target device is
a partition. This is not strictly necessary: MINIX3 can also be
installed (manually) into one or more primary partitions, requiring
that the installboot target be the entire disk. With this patch,
specifying a disk as target is now allowed, as long as the -f (force)
option is given.
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.
