We must build a directory tree structure corresponding to the files in
the .apk, and use that then in lo_apk_opendir()/readdir().

We can't just return the same subdirectory once for each time we come
across an entry that has it as a prefix in the zip directory.

Use the BSD-licensed "uthash" library (just one .h file actually) from
http://uthash.sourceforge.net/ .

This fixes commit cce76e65.

Apparently omitting parameter names is not valid C.

This allows to feed updates via a static .xml in a controlled environment.

The test doesn't do the actual jumping, but it only tests the validity
of the destination range(s).

The namespace handling in the spotlight plugin XML parser looks broken,
added some FIXMEs for that.

When creating a new page without using a page break, before a page
break, there was a remaining indicator. These are now checked and
removed to avoid such cases.

some little perf. improvements on saving spreadsheets

 - so that it is called before accessing polygon points

 - convert them to cubic beziers, which we have in basegfx

We used to patch in a simple "b" instruction with a relative offset
that has to fit in 24(+2) bits. Which was not enough in practice.

Now patch in a "ldr pc, [pc, #-4]" instead which loads PC from the
next word; in ARM code PC cotains the address of the executing
instruction + 8), and put the full address of the replacement code
into the next word.

Remove SvStrings definition and obsolete #defines.

Remove unused variables.

------
With the for loop below Insert(x,nPos) was previously applied but nPos
is initialised to the end of vector and is always incremented in every
loop iteration i.e. Insert(x,nPos) is effectively a push_back(x). Agree?
In "short SvxNumberFormatShell::FillEListWithUserCurrencys(....)"

Also get rid of SvxDelStrgs (variant of SvStrings)
