The next commit will make mode_t 32-bits, ino_t 64-bits, nlink_t
32-bits, and off_t 64-bits. However, in the protocol there is no
room for that.
When analyzing the usage of these data types we can see that of
mode_t we currently use 15 bits and that future flags (if copied
from NetBSD) are only of importance to VFS and not to the actual
file system on disk. Therefore we can get away with keeping the
protocol version of mode_t (pmode_t) 16 bits.
At this point it is unlikely that MINIX will support file systems
that can hold more than 2^32 files. Keeping the protocol version of
ino_t (pino_t) 32-bits and exposing it as 64-bits to the rest of the
system is fine.
uid_t and gid_t are already 32-bits, but in behind the scenes they're
16-bits. This is sufficient since we don't support uid/gids larger
than 2^16-1.
off_t will become 64-bits, but the protocol had room reserved
for that since it was revised years ago.
So to make the difference clear between what the protocol supports
and what is exposed to the system, we define protocol version of
these data types.

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.
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.

* Remade patch so it works with minix patch tool.
* New MINIX tar support -ox, so revert back to it
In fetch scripts, tar had been replaced by bsdtar as the prebvious
tar did not support the -o flag under minix, which is required to
prevent usage of tar file stored user and group information.
This introduces portability problems. As our new tar tool now
support that flag revert back to improve portability.
