Apart from removing these libraries because the Flash Player was deprecated
in 2017 and officially discontinued on 31 December 2020, the rtmp and useflash
settings have been removed too (they make no sense anymore).

This just deletes all the upgrade steps previous to 3.6.0. Some
small adjustments, like tweaking globals can also be applied
when needed.

Also includes an upgrade step to prevent upgrading from any
version < 2018120300 (v3.6.0) as anti-cheating measure.

Note that in this case, there wasn't any case of upgradelib
functions being used, hence we haven't to deprecate/remove
anything in codebase. When there is such a need, that is done
in separate commits (one for each function) and documented here.

See MDL-65809 commits for an example removing/deprecating a
good number of functions.

Previous commits have removed/deprecated all the upgradelib functions
not used anymore in codebase. Deletion has been documented in corresponding

and linkcoursesectionsupgradescriptwasrun setting
- upgrade_block_positions

3.7 (min PHP 7.1) requires 3.2 (first version supporting PHP 7.1)

This just deletes all the upgrade steps previous to 3.2.0. Some
small adjustments, like adding missing MOODLE_INTERNAL or tweaking
globals can also be applied when needed.

Also includes an upgrade step to prevent upgrading from any
version < 2016120500 (v3.2.0) as anti-cheating measure.

Next commit will get rid of/deprecate all the upgradelib functions
not used anymore in codebase. (note there isn't any this time).
