[Libreoffice] [REVIEW 3-4] Update mdds to 0.5.3

[Kohei Yoshida]

Hi there,

I'd like to update mdds to 0.5.3 for the -3-4 branch and preferably the
-3-4-2 branch as well.  The attached patches would make that happen.

That should improve the performance issue raised in

https://bugs.freedesktop.org/show_bug.cgi?id=38028

but since this affects the general performance of the matrix code, it
should speed up calculations involving matrices in other use cases as
well.

I've already updated mdds to 0.5.3 on master, so this is for the 3.4.x
branch only.

The change in mdds since 0.5.2 is very minimal.  In fact, the only
change I made is in the filled matrix storage backend code, and the new
implementation passes all the tests therein (on Linux and Windows).
Memory leak tests show no leakages.

Review appreciated.

Kohei
