- fix for "out of extents" panic;
- return ENOENT when a file name does not exist;
- inode count sanity check upon unmount.

iso9660fs has been cleaned up and debugged. It now supports:
* ISO 9660 Level 3,
* System Use Sharing Protocol (SUSP),
* Rock Ridge Interchange Protocol (RRIP).
The following Rock Ridge features are supported:
* POSIX file attributes (PX),
* POSIX device number (PN),
* Symbolic links (SL),
* Alternate file name (NM),
* Timestamps in 7-byte format (TF).
- remove the buffer pool, inode bitmap, and inode hash table, and
simplify the code accordingly;
- use theoretically slightly more optimal buffer management;
- put the entire source in one file, instead of having many files
with one or two functions each;
- convert the code to KNF style.

In order to avoid creating libfsdriver exceptions, two changes to VFS
are necessary:
- the returned position field for reads/writes is no longer abused to
return the new pipe size; VFS is perfectly capable of updating the
size itself;
- during system startup, PFS is now sent a mount request, just like all
other file systems.
In proper "two steps forward, one step back" fashion, the latter point
has the consequence that PFS can no longer drop its privileges at
startup. This is probably best resolved with a more general solution
for all boot image system services. The upside is that PFS no longer
needs to be linked with libc.

UDS expects the device number of the actual socket, not the device on
which the socket happens to reside. The code worked only because PFS
returned the same value in the st_dev stat field, which it will have
to continue doing for a while now.

The new functionality aims to save each file system server from having
to implement its own block I/O routines just so that it can serve as a
root file system. The new source file (bio.c) lists the requirements
that file system servers have to fulfill in order to use the routines.

The file system may not be expecting these upcalls at arbitrary
moments, while they serve only as a performance optimization anyway.

The minixfs library only ever submits vector elements (and reads) of
the system page size. The test implementation was expecting vector
elements (and reads) of the file system block size. The resulting
mismatch caused I/O to fail in various ways, even though this did not
have an effect on the actual test.

Updating the current block size before flushing the cache, which still
contained blocks with the old block size, resulted in triggering an
assert on position alignment.

This library provides new abstractions for the upper (VFS) side of
file system services, and should be used for all file system service
implementations from now on. It provides the following functionality:
- a function call table abstraction, hiding the details of the
VFS-FS protocol with simple parameters;
- a (currently limited) number of per-function steps required for
all file system implementations, such as copying in and out path
names and result buffers;
- a default implementation for multicomponent path lookups, such
that the file system merely has to implement resolution of single
components at a time;
- an abstraction for copying data from and to the file system, which
allows transparent intraprocess copying as required for the lookup
implementation;
- a set of functions to simplify getdents implementations.
The message loop provided by the library is currently for use by
single-threaded file system implementations only. Multithreaded file
system services may use the more low-level message processing
functionality.
Protocol-level optimizations such as including names in protocol
messages may be hidden entirely in this library. In addition, in the
future, the lookup implementation may be replaced by a single-
component lookup VFS/FS protocol request as part of a VFS name cache
implementation; this, too, can be hidden entirely in this library.

This is an attempt at simplifying the Makefile, by specifying the home
directory of every utility, instead of trying to guess depending on some
variable.
While this is a bit more verbose, this simplifies the logic. This also makes
it simpler to add / remove programs from the ramdisk.

- With this patch, DDEKit no longer uses IRQ number as interrupt ID
and more IRQ numbers can be used with it
- DDEKit IRQ code, will now check return values and panic on error

- This improves the user messages.
- This update the pkgsrc checkout rules to point to the new repository,
as well as the new work process we are introducing.
- This introduces rules for the MINIX sources, as we don't have the
space anymore to distribute them by default on the official ISO.

This script runs a subset of all the available test. This is aimed at
first time users which might be surprised by the warnings and time the
full test suite takes.
This runs all the tests which in case of success only print "ok" and
don't take too much time to run, independently of the network
connectivity.

There is a tic command which comes with a package. When this package is
installed, this prevent "make build" from completing, as the packaged
tic as incompatible arguments.

- Removed an "export CPPFLAGS=${FLAG}" which prevented proper settings
from the environment to be passed to the build step.
- Re-arranged variable settings at the top, so that we don't need
to evaluate the argument to vfat mkfs command anymore in
arm_sdimage.sh
- "Merged" both script for easier comparison in the future.

The bin user doesn't need an actual home folder to run the tests. As
such this account should not be used in 'su - bin'. To be noted that
'su bin' still works as expected, and allow to run the minix test set
as usual.

We used to have an account "ast" as a token to Andrew S. Tannebaum,
the creator of MINIX. The account was disable by default, with no
possible way to login.
It seems it generates more confusion than it is worth, so this removes it.
The default skeleton user profile is still stored into /etc/ast instead
of the usual /etc/skel.
