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.

This introduces a new "controlled link" file type where the file is not
stored in Moodle - but Moodle will control the access permissions on the file.
Plugins can "freeze" a filearea which means Moodle will take ownership of all the remote
files of this type.
When accessing a file, if the "filebrowser" infomation indicates the current user can write to the file, they
will be granted temporary write access.
Part of MDL-58220
This change moves all operations which deal with the fetching/updating, or
setting of files from the file_storage class into a new file_system class.
A new file_system can be specified in the config.php and used to replace
all relevant methods in order to move the file system component to an
alternative solution.
