For dynamically linked executables, the interpreter is passed a
file descriptor of the binary being executed. To this end, VFS
opens the target executable, but opening the file fails if it is
not readable, even when it is executable. With this patch, when
opening the executable, it verifies the X bit rather than the R
bit on the file, thus allowing the execution of dynamically
linked binaries that are executable but not readable.
Add test86 to verify correctness.

- The lmfs_get_block*(3) API calls may now return an error. The idea
is to encourage a next generation of file system services to do a
better job at dealing with block read errors than the MFS-derived
implementations do. These existing file systems have been changed
to panic immediately upon getting a block read error, in order to
let unchecked errors cause corruption. Note that libbdev already
retries failing I/O operations a few times first.
- The libminixfs block device I/O module (bio.c) now deals properly
with end-of-file conditions on block devices. Since a device or
partition size may not be a multiple of the root file system's block
size, support for partial block retrival has been added, with a new
internal lmfs_get_partial_block(3) call. A new test program,
test85, tests the new handling of EOF conditions when reading,
writing, and memory-mapping a block device.

The new syslogd(8) does not create log files that do not already
exist, and thus, we adopt the NetBSD way of creating them.

The primary reason for the import is a likely GPL taint of the
original MINIX3 syslogd. As a result, this import may still
have some rough edges.

This test connects to a remote HTTP server to retrieve files, using various
chunk sizes and concurrency settings to exercise the network stack. The test
is only performed is USENETWORK=yes. This test requires the following URLs to
remain available: http://test82.minix3.org/test1.txt and
http://test82.minix3.org/test2.bin. The former contains a 'Hello world'
message followed by a newline, the latter all 16-bit values in increasing
order, using big-endian notation.

These new tests are largely based on the code from test 56 (UDS). Common code
is moved into a separate file common-socket.c. In some instances the tests
are too strict for TCP/UDP sockets, which may not always react instantly to
whatever happens on the other side (even locally). For these cases, the
ignore_* fields in struct socket_test_info indicate that there needs to be
an exception. There are also tests where it seems the functionality of inet
is either incorrect or incomplete with regard to the POSIX standard. In these
cases, the bug_* fields are used to document the issues while avoiding
failure of the test.

This patch adds support for Unix98 pseudo terminals, that is,
posix_openpt(3), grantpt(3), unlockpt(3), /dev/ptmx, and /dev/pts/.
The latter is implemented with a new pseudo file system, PTYFS.
In effect, this patch adds secure support for unprivileged pseudo
terminal allocation, allowing programs such as tmux(1) to be used by
non-root users as well. Test77 has been extended with new tests, and
no longer needs to run as root.
The new functionality is optional. To revert to the old behavior,
remove the "ptyfs" entry from /etc/fstab.
Technical nodes:
o The reason for not implementing the NetBSD /dev/ptm approach is that
implementing the corresponding ioctl (TIOCPTMGET) would require
adding a number of extremely hairy exceptions to VFS, including the
PTY driver having to create new file descriptors for its own device
nodes.
o PTYFS is required for Unix98 PTYs in order to avoid that the PTY
driver has to be aware of old-style PTY naming schemes and even has
to call chmod(2) on a disk-backed file system. PTY cannot be its
own PTYFS since a character driver may currently not also be a file
system. However, PTYFS may be subsumed into a DEVFS in the future.
o The Unix98 PTY behavior differs somewhat from NetBSD's, in that
slave nodes are created on ptyfs only upon the first call to
grantpt(3). This approach obviates the need to revoke access as
part of the grantpt(3) call.
o Shutting down PTY may leave slave nodes on PTYFS, but once PTY is
restarted, these leftover slave nodes will be removed before they
create a security risk. Unmounting PTYFS will make existing PTY
slaves permanently unavailable, and absence of PTYFS will block
allocation of new Unix98 PTYs until PTYFS is (re)mounted.

Removes the following man pages:
* awk.1x -- for a version of awk we no longer have
* kermit.1x -- seems gone altogether
* macros.1x -- not useful for anyone anymore
Moves the following man pages:
* mined.1x -- Moved to minix/commands/mined/mined.1
and reformatted to use the mdoc macros instead of the
Minix macros so that it displays properly.
Removes /usr/man/man1x from the directory tree.

. can now build minix/arm using llvm and eabi - without C++

- Expose in procfs the service status and supported recovery policies.
- This adds a test (testrelpol.sh) to exercise the restart policies of
the system services and drivers.
NOTE:
The policy support information is temporarily hardcoded in ProcFS, but
this has to be replaced by properly retrieving this information from
RS, which should in turn be setup on a per service basis, at
initialization time.

With the import of Xorg, a proper separation between login-time and sub
shell-time of the environment setup is necessary.
Instead of re-developping this from scratch, I am taking the opportunity
to import the NetBSD default environment.

We have to use SOCK_SEQPACKET instead of SOCK_STREAM for client/server

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.

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

/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
