Changeset 40124 for trunk/tests/phpunit/tests/functions.php

Message:

Media: Reduce failing uploads following 4.7.1.

[39831] introduced more strict MIME type checking for uploads, which
resulted in unintetionally blocking several filetypes that were
previously valid. This change uses a more targeted approach to MIME
validation to restore previous behavior for most types.

Props blobfolio, iandunn, ipstenu, markoheijnen, xknown, joemcgill.
Fixes #39550, #39552.
