[Libreoffice] [GSOC][PATCH] Multiline inputbar

Hello There,

I'm posting here the git diff of the work I've done till now.
@Kohei Since I do not want to disturb my master branch I'm here
pasting the diff only. Please create a feature branch and apply it, so
that I can clone that branch and commit on that.
