Where calling code was previously using either the 32-bit limit, or a
value equal to SQL_INT_MAX inside a database read/write, instead use
our new constant.
This prevents automatic casting from int to double on 32 bit systems
(which have a maximum for integers of 2147483647)
Whilst Moodle will not support 32-bit systems for much longer, this is
still worth doing to prevent future issues.
- Removed redundant query to analytics_predict_samples
- Analysers API now uses recordsets to iterate through the analysable
elements. They take the last analysed time into account.
- New method for targets so there is no need to always update the last
analysis time. Useful for lightweight targets.
