PHP 7 changes how most errors are reported by PHP. Instead of reporting errors
through the traditional error reporting mechanism used by PHP 5, most errors
are now reported by throwing Error exceptions.
Use it to display meaningful SQL error messages instead of PHP fatal errors
for SQL errors.

Fixes [DBAL function sql_nextid - name is
misleading](https://tracker.phpbb.com/browse/PHPBB3-8071).
Per the tracker issue:
> This function gets the ID of the last inserted row, not the ID of the next row
to be inserted (which is difficult due to different autoincrement steps and also
lends itself nicely to race conditions).
@iwisdom replied that the naming is consistent with how PHP itself names this
functionality, but the link they posted doesn't support that (I guess this is
referring to a much older version of PHP? The comment is from 2009).

PR #2570 has added new constant to display load time information without
debug mode is being on (https://tracker.phpbb.com/browse/PHPBB3-12687).
This patch expands the total load time info with SQL/PHP load times,
while hiding the additional info with <abbr> element.
