Since the refactoring towards using the filepicker for file and picture
fields there are several variables, which are set but never read. Thus,
I removed them.
When a file or picture field was added with existing records, these
records could not be saved, since the draft area was not created
properly.

All 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_mimetypes()
- upgrade_fix_missing_root_folders_draft()
- upgrade_minmaxgrade() and upgrade_minmaxgradestepignored setting
- upgrade_course_tags()
- atto_equation_update_librarygroup4_setting()
- mod_lti_upgrade_custom_separator()
These have been kept because continue being used by restore:
- upgrade_group_members_only()
- upgrade_extra_credit_weightoverride()
- upgrade_calculated_grade_items()
This just deletes all the upgrade steps previous to 3.0.0. 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 < 2015111600 (v3.0.0) as anti-cheating measure.
Next commit will get rid of/deprecate all the upgradelib functions
not used anymore in codebase.
Due to Moodle 2.7 and Moodle 3.4 not having a common compatible php version
between them to upgrade from Moodle 3.4 from Moodle 2.7 you'll need to upgrade
to a higher version first or upgrade php at the same time as upgrade,
this encourages the former.
* Introduce a new php compatible library which can be used
early in execution, without Moodle dependencies
* Use it where we previously had hardcoded checks
This was originally suggested in MDL-39007.
Removed the concat to generate the uniqueid field for the popup
notifications data. The concat can't be used directly in the SQL because
the syntax changes between databases. The sql_concat helper can't be
used because it assumes all values are database columns (which they
aren't in this case).
Instead I've just removed the uniqueid field because it isn't required
for the union all to work and the field isn't being used by anything.
This should fixed the compatibility issues between databases.
