3cbc908a6e lib: Add better guard against huge malloc
See dda6857fee
and https://bugzilla.redhat.com/show_bug.cgi?id=1656518

When the number of lines to assemble is 1, the median_filter() function
would be passed -1 as its size as it was calculated with:
(num_lines / 2) - 1
so (1 / 2) - 1 = 0 - 1 = -1

Add a guard to stop drivers trying to assemble single lines. This
doesn't however fix the vfs5011 driver that tried to do that.

46ad86fab2 doc: Remove empty "poll" section
In commit 231b8f9, when porting from doxygen to gtk-doc, we created a
