Some of GLib's unit tests are under an apparently GLib-specific
permissive license, vaguely similar to the BSD/MIT family but with the
GPL's lack-of-warranty wording. This is not on SPDX's list of
well-known licenses, so we need to use a custom license name prefixed
with LicenseRef if we want to represent this in SPDX/REUSE syntax.
Most of the newer tests seem to be licensed under LGPL-2.1-or-later
instead.

This currently just implements the same functionality as the existing
`stat()`/`fstat()`/`fstatat()`/`lstat()` calls, although where a reduced
field set is requested it may return faster.
Helps: #1970
The third parameter of the thumnail_verify() function had been updated to
const GLocalFileStat, so update the thumbnail-verification test likewise
so that the test works properly on all supported platforms.

This code was added for use by the G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID
file attribute, but may end up being used elsewhere (e.g. in GVfs) as well.
As it’s dealing with untrusted external files, and the non-trivial PNG file
format, this commit adds several test cases to cover valid and invalid PNG
files.
The security model for the thumbnail verification code is that the user’s
cache directory is untrusted, and potentially any PNG file which is passed
to the verifier has been manipulated arbitrarily by an attacker.
This is a follow-up to commit fe7069749f.
