Bring back xterm pasting with middle mouse

Problem reported by Jan Synáček.
Solution suggested by Stefan Monnier (Bug#23519).
* lisp/isearch.el (isearch-mode-map): Add a binding for xterm-paste.
(xterm--pasted-text): New decl.
(isearch-xterm-paste): New function.
* lisp/term/xterm.el (xterm--pasted-text): New function,
taken from xterm-paste internals.
(xterm-paste): Use it.
