caecb2f4c0 Third attempt at removing machdep.h and using ALIGN from <sys/param.h>. 
The initial stack_block is staticly allocated and will be aligned
according to the alignment requirements of pointers, which does not
necessarily match the alignment enforced by ALIGN. To solve this a
more involved change is required: remove the static initial stack
and deal with an initial condition of not having a stack at all. This
change is therefore more risky than the previous ones, but unavoidable
(other than not using the platform default alignment).

5b94264c20 Fix format string errors relating mainly to the use of %qu to print off_t's. 
Instead use %ju and cast the argument.

WFORMAT=0 is still required in the Makefile because gcc warns about
some strftime() calls (I don't think this behaviour is useful.)

684370e703 Use a non-bogus type for representing the values of offsets in structs. 
off_t is for offsets in files, and it is signed so it was no better
than the original type of int for avoiding warnings from broken lints,
except accidentally on machines like i386's where size_t is smaller
than off_t.

0d3bcc2e80 Make the threatened fts(3) ABI fix. FTSENT now avoids the use of the struct 
hack, thereby allowing future extensions to the structure (e.g., for extended
attributes) without rebreaking the ABI.  FTSENT now contains a pointer to the
parent stream, which fts_compar() can then take advantage of, avoiding the
undefined behavior previously warned about.  As a consequence of this change,
the prototype of the comparison function passed to fts_open() has changed
to reflect the required amount of constness for its use.  All callers in the
tree are updated to use the correct prototype.

Comparison functions can now make use of the new parent pointer to access
the new stream-specific private data pointer, which is intended to assist
creation of reentrant library routines which use fts(3) internally.

5965373e69 - Introduce a new struct xvfsconf, the userland version of struct vfsconf. 
- Make getvfsbyname() take a struct xvfsconf *.
- Convert several consumers of getvfsbyname() to use struct xvfsconf.
- Correct the getvfsbyname.3 manpage.
- Create a new vfs.conflist sysctl to dump all the struct xvfsconf in the
  kernel, and rewrite getvfsbyname() to use this instead of the weird
  existing API.
- Convert some {set,get,end}vfsent() consumers to use the new vfs.conflist
  sysctl.
- Convert a vfsload() call in nfsiod.c to kldload() and remove the useless
  vfsisloadable() and endvfsent() calls.
- Add a warning printf() in vfs_sysctl() to tell people they are using
  an old userland.

After these changes, it's possible to modify struct vfsconf without
breaking the binary compatibility.  Please note that these changes don't
break this compatibility either.

When bp will have updated mount_smbfs(8) with the patch I sent him, there
will be no more consumers of the {set,get,end}vfsent(), vfsisloadable()

Provided the (previously missing) dependency on source files
for intermediate .msg files.

Provided the default for NLSSRCDIR (defaults to .CURDIR).

Slightly changed the API: NLS should now list plain locale
names, without the .msg suffix.

When included from bsd.prog.mk, NLSNAME defaults to PROG.

d86825beb8 Instead of keeping just the jobid of the most recently bg'd or fg'd job, 
keep a linked list of the jobs, most recently used first. This is required
to support the idea of `previous job', and to allow the jobs fg and bg
default to be correct according to POSIX.

52183d0145 Add uuidgen(2) and uuidgen(1). 
The uuidgen command, by means of the uuidgen syscall, generates one
or more Universally Unique Identifiers compatible with OSF/DCE 1.1
version 1 UUIDs.

From the Perforce logs (change 11995):

Round of cleanups:
o  Give uuidgen() the correct prototype in syscalls.master
o  Define struct uuid according to DCE 1.1 in sys/uuid.h
o  Use struct uuid instead of uuid_t. The latter is defined
   in sys/uuid.h but should not be used in kernel land.
o  Add snprintf_uuid(), printf_uuid() and sbuf_printf_uuid()
   to kern_uuid.c for use in the kernel (currently geom_gpt.c).
o  Rename the non-standard struct uuid in kern/kern_uuid.c
   to struct uuid_private and give it a slightly better definition
   for better byte-order handling. See below.
o  In sys/gpt.h, fix the broken uuid definitions to match the now
   compliant struct uuid definition. See below.
o  In usr.bin/uuidgen/uuidgen.c catch up with struct uuid change.

A note about byte-order:
        The standard failed to provide a non-conflicting and
unambiguous definition for the binary representation. My initial
implementation always wrote the timestamp as a 64-bit little-endian
(2s-complement) integral. The clock sequence was always written
as a 16-bit big-endian (2s-complement) integral. After a good
nights sleep and couple of Pan Galactic Gargle Blasters (not
necessarily in that order :-) I reread the spec and came to the
conclusion that the time fields are always written in the native
by order, provided the the low, mid and hi chopping still occurs.
The spec mentions that you "might need to swap bytes if you talk
to a machine that has a different byte-order". The clock sequence
is always written in big-endian order (as is the IEEE 802 address)
because its division is resulting in bytes, making the ordering
unambiguous.

borrow from there.  Constify things to match.  (why aren't these
functions in a lib anyway ?)

Make everything static and set WARNS?=5.

The way the "df diskdevice" thing works for unmounted diskdevices
is not very general.

Modify the math in some of the paranoid checks for buffer overflow to
account for the fact we now are dealing with the actual size of the
buffer.  Remove the static qualifier for arg_max, and the bogus setting
of it to -1.
