* Add _SC_LINE_MAX to unistd.h (value of 15 from NetBSD).
* Add _SC_LINE_MAX case to sysconf(3) in libc.
* usr.bin/nl itself required no Minix specific changes.

- exclude .git instead of .svn when using local source (-c);
- put the git tag (or "copy") in /etc/version rather than something
outdated related to SVN;
- remove SVN-specific -s flag (suggested by Erik).

. initial workaround for assert() firing on iovec
size on ARM. likely due to alloc_contig() allocating
unusually mapped memory in STATICINIT.
. for the same reason use the regular cache i/o functions
to read the superblock in mfs - avoid the alloc_contig()
that STATICINIT does.

A printf statement that only gets compiled when DEBUG_SEM is
defined had a '%' conversion without a corresponding argument.
This patch adds the argument.

Reason: Introduces new device nodes and removes old devices nodes which where unintended at this point.
When compiling with -O3 gcc seems to be a lot stricter on its checks for
index out of bounds error.

test75 sometimes false-fails if something else is going on
at the same time, presumably because the child doesn't spin
enough to register a nonzero getrusage() cpu time value, as
spin() uses the real time to limit the spinning.
this change forces spin() to do a minimum amount of spinning
before exiting, regardless of scheduling.

Before this change overflowing the free running clock counter
between the time the timer was read and the time the overflow
check was done resulted in read_tsc_64 returning a to high value.

When we start using a new pagetable (for a new process)
the last part is to ensure the pagetable itself can be
accessed by VM. This is done in pt_bind by updating
the "pagetable of pagetables" and we want this mapping
to match other mappings to the l1 pagetable.

A script that creates a HD image ready to be booted by an x86
emulator, ready to work in a crossbuild environment.
It's really just for qemu/kvm as there's no boot code in
the MBR and no bootloader installed so we rely on the in-kvm
multiboot implementation for now. This is very convenient for
passing args too.
To minimize reliance on external tools, we use the Minix
'partition' utility to write the partition table of the HD
image, which therefore has to be compiled natively.
. new script releasetools/x86_hdimage.sh
. natively compile minix 'partition' utility
. make <machine/partition.h> 64-bit safe for it

The sht21 temperature and humidity sensor holds the i2c bus while
an ADC conversion is in progress. For example, a temperature
measurement is requested, a read operation is started, and the
sht21 doesn't respond to the read request until the result of
the measurement is ready. The conversion time isn't constant.
On rare occations (one in hundreds of samples) the timeout in the
i2c driver expires returning an error.
The example code from Sensirion, the sht21's manufacturer, suggests
a bus timeout of 1 second to accommodate the sht21. This commit
increases the bus timeout to 1 second. The timeout is only reached
when chips do not respond normally, so the change doesn't affect the
performance of any other drivers.

Many i2c device drivers used similar code to access registers on
the ICs they drive. This commit implements that functionality in
libi2cdriver and updates the drivers to use the library instead of
their own register access functions. The net result is 375+ fewer
lines of code and less work for people developing new drivers.
The two exceptions were cat24c256 and parts of tda19988. They access
the bus in uncommon ways. It doesn't make sense at this time to
move their read/write functions into libi2cdriver.
