Delete support for the LESSOPEN and LESSCLOSE environment variables
aka the "Input Preprocessor": it's been a source for multiple
security bugs in the past as everything has to deal with handling
arbitrary filenames and generally resulted in multiple TOCTOU issues.
The base system never included a default LESSOPEN setting like some
Linux distributions did, but it's a suds-filled sink full of knives
to try to use safely.

less uses a correct raceless signal method of indicating signal events in
a volatile sig_atomic_t variable, and then processing events in the mainloop.
But only one variable was used for 3 signals, with |= bit operations which
are signal interruptable!  Rewrite the code to use 3 independent variables
and cleanup how the mainloop observes indications.

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.
