f9d4afb439 Put some static keywords in the source code.
For these simple utilities, it doesn't harm to make all global variables
static. In fact, this allows the compiler to perform better forms of
optimisation and analysis.

e9cbc9a770 Teach cat(1) and cp(1) to use a larger buffer if enough memory is present
in the system. A simple heuristics is used to detect what is "enough"
memory: if number of physmem pages is greater than 32k (equalling 128 MB
on machines with 4 kB pages).

Typical immediate result of these changes is reduction in context switches
and the goal is to increase efficiency by using large buffers:
before: /usr/bin/time -hlp cat file1 > file2
...
       163  voluntary context switches
     11194  involuntary context switches
after: /usr/bin/time -hlp ./cat file1 > file2
...
       417  voluntary context switches
       272  involuntary context switches

78a3801de3 Drag cat(1) kicking and screaming into the late 1980's:
o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
  they already are.

1b00c916a1 The "cat - -" feature was broken by the last commit.
Restore the code that avoided closing and reopening
stdin.  This is also required by POSIX.  As a bonus,
enable multiple stdin reads with the -benstv flags,
by resetting the EOF condition on stdin.

5091080e15 Use Dq Li (double-quoted literal) instead of Ic (internal command) to
mark up a sample invocation, since it is not a command internal to the
described utility.

to the utility or one of its internal commands.

2192b407ac Sync us up to OpenBSD's cat.1 v1.18 and cat.c v1.9.
This gets rid of a bogus cast of NULL in setbuf().
Lets us know the buffer malloc failed.

Reworks the manpage a bit to make it more mdoc(7) compliant, adds
examples.

8d72a3d7f6 Merge in the NetBSD changes to cat.c. These appear to have come from
the 4.4 lite 2 tape as well.  There are now only two diffs between
NetBSD's cat and FreeBSD's cat:
	getopt return value is -1 on NetBSD and EOF on FreeBSD.
	NetBSD has added setlocale calls before anything else.
