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.

. the minix init started rc with the 'bootargs' variable.
this can now be cleanly passed to rc by executing sysenv
from the ramdisk rc script.

. let you specify IMG as a block device directly. this minimizes
i/o (only write used parts of the filesystem) and so turnaround
time - while still allowing the big default FS size.

It is currently too broken to be of any use anyway. Fixes are pending,
which is why this patch is intended to be reverted before those are
merged.
For the time being, the following tools can be used to access cdroms:
- isodir
- isoinfo
- isoread
- writeisofs

They can be deactivated with -DNDEBUG, which is why they can't contain
code which should always be run.
It seems the local implementation of USB_ASSERT doesn't honor the
CPP flags NDEBUG, this will be corrected in a later patch.

Known limitations:
- comment for now testisofs, as iso9660fs is known to be broken.
Benefits:
- near 3x speed improvement on C++ code compilation, bringing down
make build to from 44min down to 21min.
- Allows for X applications to work properly, which should be available
in near-term future through pkgsrc for 3.3.0.

- adapt an arithmetic expression for the new sh
- update the fsck call to use the main fsck wrapper instead of a
specific fsck version.

. if a up/down script isn't specified, devmand

. skip script at a higher level when missing,
and add asserts for expected strings at the lower level

The memory used to be in its own memory region, but is now a part of
a larger memory region which is already being freed anyway.

- replace a stray assert(0) with abort()
- remove unrequired copy-pasted #undef NDEBUG
- replace some #if NDEBUG by #if DEBUG as they protect debug printf()s.

- assert() is macro which is defined as empty, while panic is always
present. I added an explicit abort() after the macro to make sure the
function never returns in case of wrong flags.
- Fixed gcc build with -NDEBUG, -Os for ARM.
* A few 'may be used uninitialized' messages
* A few new missing support library functions where added in libminc.

Do not build clang and llvm libraries with debug symbols, when built as
a cross-compilation tool.
This saves a lot of space (about 4G), and hopefully also some
compilation time.

The conversion was never properly implemented for asynchronous
character drivers, and got lost during the removal of the
synchronous character protocol.

/etc/profile enables by default tabcompletion, as well as emacs mode,
in order to keep the old MINIX ash behavior.
Note: The shell now refuses to source a script without a relative or
absolute path.
This means:
- '. myscript.sh' fails, while
- '. ./myscript.sh' succeeds
