Most systems provide the full version number in the
'release' field and the kernel version in 'version'.
Minix used to split the full version number between
release and version which caused problems for pkgsrc
and other applications. This patch brings Minix's
uname in line with other systems such as NetBSD.
It also brings the getty banner in line with NetBSD.
Old Minix uname:
sysname->Minix
nodename->10.0.2.15
release->3
version->2.1
machine->i686
New Minix uname:
sysname->Minix
nodename->10.0.2.15
release->3.2.1
version->Minix 3.2.1 (GENERIC)
machine->i686

* Renamed struct timer to struct minix_timer
* Renamed timer_t to minix_timer_t
* Ensured all the code uses the minix_timer_t typedef
* Removed ifdef around _BSD_TIMER_T
* Removed include/timers.h and merged it into include/minix/timers.h
* Resolved prototype conflict by renaming kernel's (re)set_timer
to (re)set_kernel_timer.

Not all services involved in block I/O go through VM to access the
blocks they need. As a result, the blocks in VM may become stale,
possibly causing corruption when the stale copy is restored by a
service that does go through VM later on. This patch restores support
for forgetting cached blocks that belong to a particular device, and
makes the relevant file systems use this functionality 1) when
requested by VFS through REQ_FLUSH, and 2) upon unmount.

Previously, VFS would reopen a character device after a driver crash
if the associated file descriptor was opened with the O_REOPEN flag.
This patch removes support for this feature. The code was complex,
full of uncovered corner cases, and hard to test. Moreover, it did not
actually hide the crash from user applications: they would get an
error code to indicate that something went wrong, and have to decide
based on the nature of the underlying device how to continue.
- remove support for O_REOPEN, and make playwave(1) reopen its device;
- remove support for the DEV_REOPEN protocol message;
- remove all code in VFS related to reopening character devices;
- no longer change VFS filp reference count and FD bitmap upon filp
invalidation; instead, make get_filp* fail all calls on invalidated
FDs except when obtained with the locktype VNODE_OPCL which is used
by close_fd only;
- remove the VFS fproc file descriptor bitmap entirely, returning to
the situation that a FD is in use if its slot points to a filp; use
FILP_CLOSED as single means of marking a filp as invalidated.

The T_DUMPCORE implementation was not only broken - it would currently
produce a coredump of the tracer process rather than the traced
process - but also deeply flawed, and fixing it would require serious
alteration of PM's internal state machine. It should be possible to
implement the same functionality in userland, and that is now the
suggested way forward. For now, also remove the (identical) utilities
using T_DUMPCORE: dumpcore(1) and gcore(1).

These days, DEV_OPEN calls to character drivers block the calling
thread until completion or failure, and thus never return SUSPEND to
the caller. The same already applied to BDEV_OPEN calls to block
drivers. It has thus become impossible for a process to enter a state
of being blocked on a device open call.
There is currently no support for restarting device open calls to
restarted character drivers. This support was present in the _DOPEN
logic, but was already no longer triggering. In the future, this case
should be handled by the thread performing the open request.

- change all sync char drivers into async drivers;
- retire support for the sync protocol in libchardev;
- remove async dev style, as this is now the default;
- remove dev_status from VFS;
- clean up now-unused protocol messages.

- pass in file system type through mount(2), and return this type in
statvfs structures as generated by [f]statvfs(2);
- align mount flags field with NetBSD's, splitting out service flags
which are not to be passed to VFS;
- remove limitation of mount ABI to 16-byte labels, so that labels
can be made larger in the future;
- introduce new m11 message union type for mount(2) as side effect.

eepromread could only read EEPROMs through the /dev/i2c interface.
Once the cat24c256 driver is started and claims/reserves the
device, it can no longer be read through the /dev/i2c interface.
This patch adds support for reading from EEPROMs through the
/dev/eeprom interface. For example, to read the on-board eeprom
on the BBB, one would do `eepromread -f /dev/eepromb1s50 -i`.

. build writeisofs as a native tool too for it
. also mkfs.mfs: make missing file in proto nonlethal
. make setup script a little more self-sufficient
. hdboot: use INSTALL_FILE instead of INSTALL so that the
results get added to the METALOG

Replaces commands/hexdump as well as commands/od.
No Minix-specific changes were needed.
test/testsh2.sh was modified to match the spacing
used in the output of the NetBSD od command.

Replaces commands/write. No Minix-specific changes needed.
The NetBSD version lacks a few features that were present
in the Minix version: cbreak mode, verbose, and shell escapes,
but the main write(1) functionality is there and working.

Reason: Introduces new device nodes and removes old devices nodes which where unintended at this point.
