libexec: detect short files
if an exec() fails partway through reading in the sections, the target
process is already gone and a defunct process remains. sanity checking
the binary beforehand helps that.
test10 mutilates binaries and exec()s them on purpose; making an exec()
fail cleanly in such cases seems like acceptable behaviour.

vm: fix sanity checks on arm
The 'polarity' of the RW bit is inversed on ARM, causing one
of the sanity check compensations to fail. ARM now runs basic
stuff with sanity checks passing.

Fix command line history in ash
Also did some cleanup in ash sources, to make minix modifications
more obvious, as well as some simplifications (by removing code which
is never compiled)
Removed EDITLINE support, use libedit, which does the termcap/terminfo
handling.

ARM: provide free running clock to replace ccnt
The Cycle CouNTer on ARM cannot be used reliably as it wraps around
rather quickly and can be altered by user space (on Minix). Furthermore,
it's buggy when wrapping and is not implemented at all on the Linaro
Beagleboard emulator.
This patch programs GPTIMER10 as a free running clock at 1.625 MHz (it
doesn't generate interrupts). It's memory mapped into every process,
which enables libsys to provide micro_delay().

arm: make signal handlers work
A few kernel and calling convention adjustments to make sigsend and
sigreturn work for arm.
. provide a arch_proc_setcontext for earm in kernel
. set LR in context of signal handler to provide a proper
return address (to __sigreturn)
. change __sigreturn to retrieve the sigcontext pointer
from the sigframe struct and pass it to _sigreturn() in r0

kernel, which has to switch to virtual addressing

GNU tools: improvements to fetching process
- Do not run the fetch.sh script every time
- Do not run the configure script with MKUPDATE=yes (build.sh -u)
- The fetched GNU source are hidden from `git status`
- With CLEANFETCHED=yes, `nbmake -C tools cleandir` will remove the
fetched GNU source and return the MINIX tree to its pristine state.
- Avoid (harmless) message when building in parallel, about find
running against an inexistant path
Notice that the GNU tools are "installed" on every run, even with
MKUPDATE=yes; this is a feature of the NetBSD build system, because
in case of changes in dependencies it is impossible to know them.
See commit 1.27 2004-06-12 of tools/Makefile.gnuhost in NetBSD's src/
The downloaded tarballs are not removed with CLEANFETCHED:
they are supposed to be unmodified, and the exact name is not known
to the Makefile's, since it is engraved in each fetch.sh script (and
we do not want to have the same information in several places.)

ARM: disable __minix_init for now
On ARM we can't yet globally map pages into every process. So now that
we correctly receive the pointer to the globally mapped kern_info

Due to the ABI we are using we have to use the earm architecture

Reverting back to default value of MKARZERO
The value was changed to no for cross-building as the old binutils

This flags make sure that AR zeroes out some timestamps and uid/gid

ARM: fix clock
The GPTIMER1 clock is configured to run at 32 kHz and generate
(overflow) interrupts every 1 ms. However, the Timer Overflow Wrappping
Register (TOWR) was configured to filter every other interrupt. This
caused to the internal 'realtime' value to be off.
