LSC: Small correction, using the group name is not secure in cross-build
setups, replaced by the numerical gid to ensure proper operation.

Periods are allowed in Make variable names, which let us simplify
a bit the Makefile.

This add an explicit test on the obsolete _MINIX define, unset it and
replace it with _NETBSD_SOURCE.
This should help compile a lot of packages relying on autotools in pkgsrc.

When a service fails to initialize, RS exits the service. When injecting
faults this is undesired behavior. With this patch, we're going to assume
that when starting services with the -b flag (no binary exponential
offset), we don't want to exit the service but simply restart the
initialization.

Make the frclock functions similar to the tsc utility functions. This
way, we can call frclock functions from the framebuffer driver which
will use frclock on ARM and tsc on X86.
Also, frclock_64_to_micros computed seconds, not microseconds

libchardriver does not support DEV_REOPEN and will return ERESTART
when you do try it. This made VFS unhappy and concluded erroneously
that the driver was EDEADEPT.
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.
. phys_copy() (taken from memcpy) can legitimately
cause pagefaults below the source/dest address due

Interrupts where not correctly masked while in kernel, which
breaks one of the current main assumptions.
Also remove some duplication on ARM asm files, and add a function
to check the status of ARM irqs (not compiled by default)

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.
- 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.
- 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).
- 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.
There is no need to set/clear PxCMD.FRE on every port start/stop.
Also remove some already useless and now also incomplete port
reinitialization at startup.
. signed 64-bit divide incorrectly tested for sign compensation
bits in the NEG (R5) register, causing the signedness of the
quotient and modulus to be wrong for negative numerators.
Fixes test45 on ARM.

. the total amount of memory in the system didn't include the memory
used by the boot-time modules and some dynamic allocation by the
kernel at boot time (to map in VM). especially apparent on our
ARM board with 'only' 512MB of memory and a huge ramdisk.
. also: *add* the VM loaded module to the freelist after it has
been allocated for & mapped in instead of cutting it *out* of the
freelist! so we get a few more MB free..
