I want to fit the title in the footnote and use the date space in title removing date.
You can use the optional argument for \institute:
\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\title{Donald Knuth}
\author{...}
\institute[Universität Bonn]{Rheinische Friedrich-Wilhelms-Universit\"{a}t Bonn}
\usetheme{Madrid}
\usecolortheme{beetle}
\begin{document}
\frame{\titlepage}
\frame{Blubb...}
\end{document}
I think, your footline disappeared, because it was overwritten with \setbeamertemplate{footline}[page number]

Looking at the footer definition of this template, one finds:
Since you want some bigger changes, I'd recommend to rewrite it:
You can change the widths of those boxes that are set currently with
wd=.333333\paperwidth.In a MWE, including a slightly changed version for including the institution on page two:
Choose one redefinition and put it in your preamble, maybe after some further modification.
