there's unfill-region or something builtin in emacs i think since 22,
but isn't loaded by default... (or was it in )

anyway, there's code here:

• Suggestions on Emacs's Line-Cutting Commands
  http://xahlee.org/emacs/modernization_fill-paragraph.html

or, if you want a simple code, use this:

(defun remove-line-breaks ()
  "Remove line endings in a paragraph."
  (interactive)
  (let ((fill-column (point-max)))
    (fill-paragraph nil)))
