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...
