ispyisail d7ac633043 Add a zip reader and writer for .qetz projects (bundled miniz) ...

First stage of the zipped project file discussed in #1440 (and #865):
the zip itself, nothing reads or writes a project with it yet.

miniz 3.1.2 (MIT, one .c and one .h, no zlib) is bundled unmodified in
sources/container/miniz, as the LZMA SDK is for .edz files, so builds
need nothing new. QetZip wraps it: plain ZIP with Deflate, entries stored
where asked (pictures, the mimetype entry), written through QSaveFile so
a failed save keeps the previous file, without timestamps so that the
same project gives the same bytes. Reading refuses unsafe or repeated
entry names, encrypted entries and archives over 2 GB once unpacked.

Test: tst_qetzip (round trip, same bytes twice, names refused both ways,
truncated and non-zip input). A written archive also passes unzip -t and
Python's zipfile.
