New minor version.

man-db 2.12.0 (23 September 2023)

Fixes:

• Fix some manual page portability issues with groff 1.23.0.
• Fix test failures when a working iconv is not available.
• Ensure that timestamps read from the database can go past the year 2038, even on systems where this is not the default.
• Fix manpath not parsing PATH entries with trailing slash correctly for guessing MANPATH entries.
• More accurately document the behaviour of passing file names as arguments to man without the -l/--local-file option.
• Avoid duplicate cleanup of old cat pages by both man-db.service and systemd-tmpfiles-clean.service.

Improvements:

• Update system call lists in seccomp sandbox from systemd.
• Upgrade to Gnulib stable-202307.
• Work around the Firebuild accelerator in seccomp sandbox: if this is in use then we need to allow some socket-related system calls.
• man -K now deduplicates search results that point to the same page.
• Warn if mandb drops to --user-db mode due to running as the wrong user.
• Change section title recommendations in man(1) to mention STANDARDS rather than CONFORMING TO, in line with man-pages(7).
• Add a STANDARDS section to man(1) itself.
• Document that man -K may suffer from false negatives as well as false positives.
• Take advantage of newer groff facilities to implement `man --no-hyphenation and man --no-justification`, if available.
• man -f and man -k now pass any -r/--regex or -w/--wildcard options on to whatis and apropos respectively.
• Always pass a line length to nroff, even if we believe that it matches the default.
• Allow disabling groff warnings via man --warnings, by prefixing a warning name with !.

The update will fix the man1/lexgrog.1 test failure documented in the book.
