Even more cleanups to dd(1). This is probably the culmination of the
BDEification process of dd(1). Most of the changes are from BDE's archive.
Support for negative offsets is gone again, but the case where you
lseek() onto byte -1 of something from a negative offset using seek/skip
is fixed; if you end up on -1, you won't get a false positive lseek failure.
The biggest changes are to data types (more size_t, for instance) and
argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read
until you reach the offset") due to mem devices now being D_DISK. Some
const things are now correctly declared as such, and the "case table"
building is better. The only thing that seems to be left to make dd(1)
everything TOG wants it to be is l10n.

Make the d_flags of mem devices D_DISK to signify that they are disk-like
random-seekable devices. This lets dd(1) know it can seek on them. It
also affects spec_vnopen() (IIRC), but only makes the path of execution smaller,
and does not change its behavior. This is when securelevel >= 2.
Some PnP BIOSsen return garbage in the high byte of the number-of-devices
field (or don't set the high byte at all). Clear it to avoid reporting
a silly number of devices.
When a STAT command is sent to ftpd as an out-of-band transmission during
a file transfer, the command was mishandled on every other receipt of the
command.

Implement new format specifier for strftime: %OB, alternative national
representation of the full month name. In the Russian locale, this alternative
will be "nominative case", useful when the date designate month as a whole.
E.g. month heading in a calendar. I hope it can be useful for some other
locales too.

Remove the #include of sys/param.h. It was meant to improve portability
for BSD less than 4.4 where sys/cdefs.h DNE but can be simulated with
param.h. Unfortunately, the additional include did little to actually
improve portability since we've lost portability in several other chunks
of make code (err(), sysctlbyname(), probable more).

VFS_FHTOVP.9, only used for filehandle to vnode, no access checks are done.

Make a bit more headway with dd's argument parsing, etc. get_bsz() is
renamed get_num() since it's not just about block sizes. skip and
seek can be any offset, including negative, now. Some style bogons are fixed.

Add the CR4 values for P3 SIMD enabling support. FXSR tells the cpu that
the OS does FXSAVE/FXRESTOR instructions (fast FPU save/restore) during
context switching and also enables SIMD since this enables saving the
extra CPU context that isn't saved with normal FPU regs. The other
enables the SIMD instructions to use exception 16 (FPU) error reporting.
Note, this doesn't turn on SIMD, just defines the bits.

Add text for the PN (Processor serial number) and XMM (extended SIMD/MMX2/

(those that I remember anyway).
In the words of originator:
:If an incoming connection is initiated through natd and deny_incoming is
:not set, then a new alias_link structure is created to handle the link.
:If there is nothing listening for the incoming connection, then the kernel
:responds with a RST for the connection. However, this is not processed
:correctly in libalias/alias.c:TcpMonitor{In,Out} and
:libalias/alias_db.c:SetState{In,Out} as it thinks a connection
:has been established and therefore applies a timeout of 86400 seconds
:to the link.
:
:If many of these half-connections are initiated (during, for example, a
:port scan of the host), then many thousands of unnecessary links are
:created and the resident size of natd balloons to 20MB or more.
* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
builtin commands for which no standalone utility exists. These MLINKS
replace those that were created for csh(1).
* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
as well as to the manpages of standalone utilities which are supported
as shell builtin commands in at least one of the shells. In such
manpages, explain that similar functionality may be provided as a
shell builtin command.
* Improve sh(1)'s description of the cd builtin command. Csh(1) already
describes it adequately. Replace the cd(1) manpage with a builtin(1)
MLINKS link.
* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
Ic instead of Xr for shell builtin commands.

It probably won't work, but it's worth a try.
