man*/, man-pages.7: VERSIONS, STANDARDS, HISTORY: Reorganize sections
- Add a new HISTORY section that covers the history of an API, both regarding implementations and regarding old standards. This was previously covered in VERSIONS, and in some cases in STANDARDS. - Repurpose VERSIONS to cover differing implementations in _current_ systems. - STANDARDS is reduced to only cover current versions of standards. That basically means only C11 (C99 has been superseeded by C11; C17 is just a bugfix of C11, so not really a new version), and POSIX.1-2008 (*-2001 was superseeded by *-2008; *-2017 was just a bugfix for *-2008). The section also mentions for example 'Linux', 'GNU' or 'BSD' when a non-standard API is Linux- or GNU-only or if it's (de-facto) standard in the BSDs. - In some cases content that should go into one of these sections was in NOTES. Move it from there to where it corresponds. - In the SYNOPSIS, I added [[deprecated]] in some functions that I found are deprecated by the relevant standards. - A few other related changes...
