Ensure that the printing temp selection document is not destroyed
prematurely by SwXTextView::NotifySelChanged, called via
ViewOptionAdjustStop, by retaining the temp doc object shell not
at the View but in SwRenderData.
Not restoring the view options for selections does not actually work,
because having a selection surprisingly does not imply printing a
temp document: the preview also uses a selection.

On Android, when an app is installed, arbitrary files bundled in the
app won't be unpacked into actual separate files in the file
system. They will exist only as archive entries in the .apk file
(which is a zip archive).
The SDK tooling puts such files under the /assets folder in the
.apk. The LibreOffice bootstrapping code for Android maps the .apk
file into memory.
osl_openFile() knows about the /assets special case, and uses a
separate abstraction for such memory-mapped files.
Obviously, when producing an .apk, one needs to make sure these
bundled files are not compressed, if one wants to be able to use them
directly from the memory-mapped .apk file. We do that in our test and
sample Android projects.
When mapping such files under /assets , just return a pointer to the
file's location inside the mapped .apk archive.
We can't use the old osl_unmapFile() on such mapped files, as that
would unexpectedly unmap fairly arbitrary pages of the .apk mapping,
wreaking havoc on later use of the same pages.
So, introduce a new osl_unmapMappedFile() function that takes also the
oslFileHandle originally passed to osl_mapFile(). Use this instead in
the few places where the code actually called osl_unmapFile(). Make
sure osl_mapFile() is nonexistent on Android.

WriteLine just writes a line of text, WriteByteString writes
a 16bit length of following content. It can't make sense to
suddenly stick a pascal-style string in at the end of a file
that's otherwise plain text.
original git id that introduced the use of WriteByteString here
was ea76474a back in 2002
Perhaps this worked because partial strings never ended up
as trailing content, so only ever had an empty string as
the final partial string, so a 0x0000 got appended, as
opposed to a newline, so it appeared to do the right thing.
