Remove wpath from secure mode pledge.

Upstream removed history file support for secure mode. The history file
feature is off by default already, disallowing it altogether in secure
mode allows us to drop wpath.

Added a note about it to manual page.

ok benno, deraadt

Delete what remains of the support for combining characters into
ligatures: it was incomplete (only for the Arabic script and only
for the single ligature LAM WITH ALEF) and it was implemented in a
way that is unsustainable (with a static table inside less).

If we ever want ligature support, we are better off making a fresh
start. However, for languages like Arabic and Persian, even that
wouldn't really be useful without having bidirectional support first.

Evan Silberman, and benno@)

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

trivial replacement of the home-grown IS_ASCII_OCTET()
with the standard isascii(3)

UTF-8 cleanup in the function cmd_putstr().
This function is only ever called with constant ASCII string arguments,
so actually it doesn't need any UTF-8 handling whatsoever.

Remove NULL-checks before free(), a needless comment, and a needless

Garrett D'Amore has agreed to moving his copyright line up above the
terms with the existing copyright, so it is clear it applies the same
terms.

Replace less with the cleaned-up fork of less 458 maintained by Garrett
D'Amore at https://github.com/gdamore/less-fork. This has significantly
less portability goop, has a tidied up code style, uses terminfo instead
of termcap, and is has stricter POSIX compliance.

Many of our local changes have been accepted upstream: substantial
remaining local changes are code to read help files from /usr/share
rather than compiling them in, man page and help improvements, and some
tweaks to the default options.
