If 'unix' is the first element of the stream_get_transports() result
array, array_search() will return `0` as index result which, when
negated, will result as true.
There are various places where it's not guaranteed that the
variable being used is array, and instead, can be null, bool, int...
We need to check that because php74 warns about it.
Where possible we have used the coalesce operator as
replacement for isset() ternary operations.
Trying to use values of type null, bool, int, float or resource as an
array (such as $null["key"]) will now generate a notice. This does not
affect array accesses performed by list().

This is the initial deprecation of:
* plagiarism_save_form_elements
* plagiarism_get_form_elements_module
* plagiarism_plugin::get_form_elements_module
* plagiarism_plugin::save_form_elements
This just deletes all the upgrade steps previous to 3.5.0. Some
small adjustments, like tweaking globals can also be applied
when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2018051700 (v3.5.0) as anti-cheating measure.
Previous commits have removed/deprecated all the upgradelib functions
not used anymore in codebase. Deletion has been documented in corresponding
upgrade.txt files:
- upgrade_fix_block_instance_configuration()
- upgrade_theme_is_from_family(), upgrade_find_theme_location()
and linkcoursesectionsupgradescriptwasrun setting
- upgrade_block_positions
- upgrade_fix_config_auth_plugin_names()
and upgrade_fix_config_auth_plugin_defaults()
- format_xxx_upgrade_remove_numsections(), format_xxx_upgrade_hide_extra_sections()
and format_xxx_upgrade_add_empty_sections()
- filter_mathjaxloader_upgrade_cdn_cloudflare()
and filter_mathjaxloader_upgrade_mathjaxconfig_equal()
- get_assignments_with_rescaled_null_grades()
These have been kept because continue being used by restore:
- \core\task\refresh_mod_calendar_events_task
These functions were used only by deleted upgrade steps
so it's safe to proceed with straight deletion, considering
them internal. Deletion has been documented in corresponding
upgrade.txt files:

- upgrade_fix_config_auth_plugin_defaults()
