f5cfab17d6 ldivmod, uldivmod: fix qdivrem calls
. ldivmod, uldivmod were passing the modulo argument pointer
	  in R4, which is bogus, as qdivrem expects it on the stack as
	  per the EABI, causing essentially 'random' memory to be trampled
	  by qdivrem. fix by pushing R4 before the call.
	. also add these functions to -minc so -lminc clients can be
	  linked without -lgcc

3045d2870b arm: protect state after signal handler
. set MF_CONTEXT_SET after signal handler state
	  is set so it doesn't get clobbered by the kernel
	  afterwards (i.e. by delivermsg()).

298b41b523 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.

fixes test10 on ARM.

b7ea9f3fd1 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.

252a83f614 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.

db8c1ee9d0 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().

e3e5cf6d34 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

	. fix for mappings being larger than what 1 pde can address
	  (e.g. devices memory requested on arm)
	. still requires a special case for devices memory for the
	  kernel, which has to switch to virtual addressing

866355d930 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.)
