find the escape sequence to clear the screen. OK deraadt@

Add -Wshadow to Makefile and fix the resulting warnings. Many of
the warnings are due to the use of globals with generic names,
specifically "options" and "path". I've renamed "options" to
"sh_options" since it holds the shell options and "path" to
"search_path". OK jca@ tb@

Disable ksh VI-editing mode on the install media. We need the space
savings.

authors need only to ensure there is an entry in NAME for any function/

ksh can run with pledge "stdio rpath wpath cpath getpw fattr proc exec tty"
if the mknod builtin is disabled. It looks like a lot of abilities, but
hey, this is a shell. can't open sockets or do other nasty stuff though.
(we'll leave the mknod builtin enabled on the install media for now; there
is work happening to regain the MAKEDEV performance in a different way)

generalise ksh keybinding system - bindings are no longer limited in
length and need not start with ESC or ^X; patch from marco@ feedback mpi@

Add POSIX character class support ([:alpha:] and friends) to ksh globbing.

Remove ulimit MLINK, it is a shell built-in.

Introducing mknod as a built-in. It might be against the unix
philosophy, but in this case it's worth it. ok deraadt@

lots of indentation cleanup, now ksh is readable like our other code.

Call perl directly instead of using an sh script to find it.

Remove -Wno-unused form CFLAGS and kill some unused vars found as a result of
that. ok millert@

Use sys_signame and sys_siglist instead of building a list of signal
values and names via an awk script. OK otto@

Get rid of #ifdef KSH since we don't care about building a V7 style sh and
the #ifdef KSH code is required to make a POSIX sh. From Matthias Kilian

Remove unused OS dependent #ifdef blocks, #defines and macro abstraction.

give up on amd64 -O0

XXX: build ksh -O0 for now, since it makes it a whole lot more stable.
we'll figure out what the bug is later, or maybe some of the other
fixes going in will fix it..

use cc -E for the preprocessor instead of cpp.

ok espie@ millert@

I can not reproduce the ksh -O1 issues anymore on mvme88k with the latest
snapshot, so stop disabling optimization.
