1e69cb63f4 Importing usr.bin/nl
* Add _SC_LINE_MAX to unistd.h (value of 15 from NetBSD).
 * Add _SC_LINE_MAX case to sysconf(3) in libc.
 * usr.bin/nl itself required no Minix specific changes.

for clang, fix warnings in drivers/, lib/, servers/, sys/, common/.
by turning off fatal warnings (takes effect if the default is on),
fixing warnings or reducing the warning level.

cdf2f55a90 kernel, arm ucontext: ARM DBG=-g run fixes
kernel:
	. modules can be as big as the space (8MB) between them
	  instead of 4MB; memory is slightly bigger with DBG=-g

arm ucontext:
	. r4 is clobbered by the restore function, as it's
	  used as a scratch register, causing problems for the
	  DBG=-g build
	. r1-r3 are safe for scratch registers, as they are
	  caller-save, so use r3 instead; and don't bother
	  restoring r1-r3, but preserve r4

vfs:
	. improve TLL pointer sanity check a bit

9178749e13 libc syslog, syslogd, logger, uds fixes
changes necessary for libc syslog() using a unix domain socket.

	. libc syslog: don't use send() connect() for unix
	  datagram sockets, minix wants write() and ioctl()
	. syslogd: listen on _PATH_LOG unix domain socket
	. logger: warnings fixes
	. pfs: make uds dgram socket type nonblocking so
	  syslog() doesn't block
	. vfs: add sanity check for empty fd in unpause()

33a7ac7557 vfs: mmap support
. libc: add vfs_mmap, a way for vfs to initiate mmap()s.
	  This is a good special case to have as vfs is a slightly
	  different client from regular user processes. It doesn't do it
	  for itself, and has the dev & inode info already so the callback
	  to VFS for the lookup isn't necessary. So it has different info
	  to have to give to VM.
	. libc: also add minix_mmap64() that accepts a 64-bit offset, even
	  though our off_t is still 32 bit now.
	. On exec() time, try to mmap() in the executable if available.
	  (It is not yet available in this commit.)
	. To support mmap(), add do_vm_call that allows VM to lookup
	  (to ino+dev), do i/o from and close FD's on behalf of other
	  processes.

9e88c40e40 VM: 64-bit mmap()
Some (backwards-compatible) changes in mmap() call message fields
that allow for a 64-bit offset. minix_mmap() takes an off_t and
minix_mmap64() takes a u64_t. Some mmap() work in VM goes into a
separate function, using the new fields, so that that can be re-used
when files are to be mapped (future commit).

9131e98a7d utimens(2) system call
Variant of utime(2) with struct timespec (with ns precision)
instead of time_t values; also allows for tv_nsec members
the values UTIME_NOW (force update to current time) or
UTIME_OMIT (allow to set either atim or mtim independently.)

Provides a superset of utimes(2), futimes(2), lutimes(2),
and futimens(2).
Provides the same subset of utimensat(2) as does NetBSD 6.
Also import utimens() and lutimeNS() from NetBSD-current.

15b3d77268 libc: add adjtime() system call.

Additionally, install the adjtime.2 and clock_*.2 man pages.

516fec97d9 libc: add clock_settime() system call.
This also adds the sys_settime() kernel call which allows for the adjusting
of the clock named realtime in the kernel. The existing sys_stime()
function is still needed for a separate job (setting the boottime). The
boottime is set in the readclock driver. The sys_settime() interface is
meant to be flexible and will support both clock_settime() and adjtime()
when adjtime() is implemented later.

settimeofday() was adjusted to use the clock_settime() interface.

One side note discovered during testing: uptime(1) (part of the last(1)),
uses wtmp to determine boottime (not Minix's times(2)). This leads `uptime`
to report odd results when you set the time to a time prior to boottime.
This isn't a new bug introduced by my changes. It's been there for a while.

e67fc5771d libc: add clock_getres()/clock_gettime() system calls.
In order to make it more clear that ticks should be used for timers
and realtime should be used for timestamps / displaying the date/time,
getuptime() was renamed to getticks() and getuptime2() was renamed to
getuptime().

Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2()
have been updated. In instances where a realtime was calculated, the
calculation was changed to use realtime.

System calls clock_getres() and clock_gettime() were added to PM/libc.

49ad4e8888 Spring cleanup
Remove old versions of system calls and system calls that don't have
a libc api interface anymore (dup, dup2, creat).

VFS still contains support for old system call numbers for the new stat
system calls (i.e., 65, 66, 67) to keep supporting old binaries built for
MINIX 3.2.1 (prior to the release).
