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. ok tb@ deraadt@ millert@

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. ok schwarze

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.

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.
