[stable10] future drop php 7.0

[phil-davis]

Description

This draft PR is a place to put things that are waiting to go into stable10 but that require PHP7.1+ and so cannot be merged until PHP7.0 support can be dropped.

• Increase version to 10.1 prealpha #28043 Increase version to PHP7.1 (the remaining commits from that PR that relate to PHP7.1 and thus have never been backported yet)
• Set min PHP version to 7.1 (1)
• PHP 7.1+ is required (2)
• "[Workaround] .... until Fix mocking of interface which extend Throwable sebastianbergmann/phpunit-mock-objects#402 is merged and released" 407a70d (I think this will be needed as long as we are on phpunit6, because that phpunit-mock-objects change never got into a release with dependencies for phpunit6) (3)
• (other commits from Increase version to 10.1 prealpha #28043 are already back in stable10)
• Bump doctrine/dbal from 2.7.1 to 2.8.0 #32065 2nd commit "Remove our own sqlite autoincrement hack" (needed with doctrine/dbal version bump that comes when composer PHP 7.1 happens) (4)
• Adjust drone matrix to match what is currently being done in master (actual commits from master would be from 2 years of travis and drone times!) (5)
• Disable phpstan in drone until we can sort out code fix backporting (see [stable10] Introduce phpstan #35774 that is waiting for review) (6)
• Do not test postgres:10.3 - needs more backports (I will look for what is needed for this) (7)
• Fix ExceptionPlugin.php logException like in master (this is fixed with "Introduce phpstan") (8)
  That stops the warning:

[PHP Warning:  Declaration of OCA\DAV\Tests\unit\Connector\Sabre\RequestTest\ExceptionPlugin::logException(Exception $ex) should be compatible with OCA\DAV\Connector\Sabre\ExceptionLoggerPlugin::logException(Throwable $ex) in /drone/src/apps/dav/tests/unit/Connector/Sabre/RequestTest/ExceptionPlugin.php on line 26]

Note to self: when dropping PHP7.0 we can probably also go straight to phpunit7 at the same time in stable10. PR #34921 moves to phpunit7 in core master. That could be backported on top of this stable10 code and the planets might come into alignment.

[phil-davis]

Note: see PR #31810 for what was done in master to get phpstan running and passing.
We might not want to get mixed up in all that, just for "drop PHP 7.0" - see #35774 which does "introduce phpstan" as a separate PR to stable10

[phil-davis]

This needs mariadb:10.3 changes backported from #33255
That is sorted out in a new PR #35786 which has the commits cherry-picked in a better order that reduced the conflicts along the way.
