Full switch to clang/ELF. Drop ack. Simplify. 

There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.

Changes in this commit:

	. drop boot monitor -> allowing dropping ack support
	. facility to copy ELF boot files to /boot so that old boot monitor
	  can still boot fairly easily, see UPDATING
	. no more ack-format libraries -> single-case libraries
	. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
	. drop several ack toolchain commands, but not all support
	  commands (e.g. aal is gone but acksize is not yet).
	. a few libc files moved to netbsd libc dir
	. new /bin/date as minix date used code in libc/
	. test compile fix
	. harmonize includes
	. /usr/lib is no longer special: without ack, /usr/lib plays no
	  kind of special bootstrapping role any more and bootstrapping
	  is done exclusively through packages, so releases depend even
	  less on the state of the machine making them now.
	. rename nbsd_lib* to lib*
	. reduce mtree

.Sh NAME
.Nm date
.Nd display or set date and time
.Sh SYNOPSIS
.Nm
.Op Fl ajnu
.Op Fl d Ar date
.Op Fl r Ar seconds
.Op Cm + Ns Ar format
.Sm off
.Oo Oo Oo Oo Oo Oo
.Ar CC Oc
.Ar yy Oc
.Ar mm Oc
.Ar dd Oc
.Ar HH Oc Ar MM Oo
.Li \&. Ar SS Oc Oc
.Sm on
.Sh DESCRIPTION
.Nm
displays the current date and time when invoked without arguments.
Providing arguments will format the date and time in a user-defined
way or set the date.
Only the superuser may set the date.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a
Use
.Xr adjtime 2
to change the local system time slowly,
maintaining it as a monotonically increasing function.
.Fl a
implies
.Fl n .
.It Fl d Ar date
Parse the provided human-described date and time and display the result without
actually changing the system clock.
(See
.Xr parsedate 3
for examples.)
.It Fl j
Parse the provided canonical representation of date and time (described below)
and display the result without actually changing the system clock.
.It Fl n
The utility
.Xr timed 8
is used to synchronize the clocks on groups of machines.
By default, if
timed
is running,
.Nm
will set the time on all of the machines in the local group.
The
.Fl n
option stops
.Nm
from setting the time for other than the current machine.
.It Fl r Ar seconds
Print out the date and time that is
.Ar seconds
from the Epoch.
.It Fl u
Display or set the date in
.Tn UTC
(universal) time.
.El
.Pp
An operand with a leading plus
.Pq Cm +
sign signals a user-defined format
string which specifies the format in which to display the date and time.
The format string may contain any of the conversion specifications described
in the
.Xr strftime 3
manual page, as well as any arbitrary text.
A \*[Lt]newline\*[Gt] character is always output after the characters
specified by the format string.
The format string for the default display is:
.Bd -literal -offset indent
%a %b %e %H:%M:%S %Z %Y
.Ed
.Pp
If an operand does not have a leading plus sign, it is interpreted as
a value for setting the system's notion of the current date and time.
The canonical representation for setting the date and time is:
.Pp
.Bl -tag -width Ds -compact -offset indent
.It Ar CC
The first two digits of the year (the century).
.It Ar yy
The second two digits of the year.
If
.Ar yy
is specified, but
.Ar CC
is not, a value for
.Ar yy
between 69 and 99 results in a
.Ar CC
value of 19.
Otherwise, a
.Ar CC
value of 20 is used.
.It Ar mm
The month of the year, from 01 to 12.
.It Ar dd
The day of the month, from 01 to 31.
.It Ar HH
The hour of the day, from 00 to 23.
.It Ar MM
The minute of the hour, from 00 to 59.
.It Ar SS
The second of the minute, from 00 to 61.
.El
.Pp
Everything but the minutes is optional.
.Pp
Time changes for Daylight Saving and Standard time and leap seconds
and years are handled automatically.
.Sh ENVIRONMENT
The following environment variables affect the execution of
.Nm :
.Bl -tag -width iTZ
.It Ev TZ
The timezone to use when displaying dates.
See
.Xr environ 7
for more information.
.El
.Sh FILES
.Bl -tag -width /var/log/messages -compact
.It Pa /etc/localtime
Symlink pointing to system's default timezone information file in
.Pa /usr/share/zoneinfo
directory.
.It Pa /var/log/wtmp
A record of date resets and time changes.
.It Pa /var/log/messages
A record of the user setting the time.
.El
.Sh EXAMPLES
The command:
.Bd -literal -offset indent
date '+DATE: %m/%d/%y%nTIME: %H:%M:%S'
.Ed
.Pp
will display:
.Bd -literal -offset indent
DATE: 11/21/87
TIME: 13:36:16
.Ed
.Pp
The command:
.Bd -literal -offset indent
date 8506131627
.Ed
.Pp
sets the date to
.Dq Li "June 13, 1985, 4:27 PM" .
.Pp
The command:
.Bd -literal -offset indent
date 1432
.Ed
.Pp
sets the time to
.Li "2:32 PM" ,
without modifying the date.
.Sh DIAGNOSTICS
Exit status is 0 on success, 1 if unable to set the date, and 2
if able to set the local date, but unable to set it globally.
.Pp
Occasionally, when
.Xr timed 8
synchronizes the time on many hosts, the setting of a new time value may
require more than a few seconds.
On these occasions,
.Nm
prints:
.Ql Network time being set .
The message
.Ql Communication error with timed
occurs when the communication
between
.Nm
and
timed
fails.

The
.Nm
utility is expected to be compatible with
.St -p1003.2 .

! Bootblock 1.5 - Minix boot block. Author: Kees J. Bot
! 21 Dec 1991
!
! When the PC is powered on, it will try to read the first sector of floppy
! disk 0 at address 0x7C00. If this fails due to the absence of flexible
! magnetic media, it will read the master boot record from the first sector
! of the hard disk. This sector not only contains executable code, but also
! the partition table of the hard disk. When executed, it will select the
! active partition and load the first sector of that at address 0x7C00.
! This file contains the code that is eventually read from either the floppy
! disk, or the hard disk partition. It is just smart enough to load /boot
! from the boot device into memory at address 0x10000 and execute that. The
! disk addresses for /boot are patched into this code by installboot as 24-bit
! sector numbers and 8-bit sector counts above enddata upwards. /boot is in
! turn smart enough to load the different parts of the Minix kernel into
! memory and execute them to finally get Minix started.

! jumpboot 1.0 - Jump to another bootstrap Author: Kees J. Bot
! 14 Apr 1999
!
! This code may be placed into any free boot sector, like the first sector
! of an extended partition, a file system partition other than the root,
! or even the master bootstrap. It will load and run another bootstrap whose
! disk, partition, and slice number (not necessarily all three) are patched
! into this code by installboot. If the ALT key is held down when this code
! is booted then you can type the disk, partition, and slice numbers manually.
! The manual interface is default if no numbers are patched in by installboot.

! masterboot 2.0 - Master boot block code Author: Kees J. Bot
!
! This code may be placed in the first sector (the boot sector) of a floppy,
! hard disk or hard disk primary partition. There it will perform the
! following actions at boot time:
!
! - If the booted device is a hard disk and one of the partitions is active
! then the active partition is booted.
!
! - Otherwise the next floppy or hard disk device is booted, trying them one
! by one.
!
! To make things a little clearer, the boot path might be:
! /dev/fd0 - Floppy disk containing data, tries fd1 then d0
! [/dev/fd1] - Drive empty
! /dev/c0d0 - Master boot block, selects active partition 2
! /dev/c0d0p2 - Submaster, selects active subpartition 0
