* lisp/term/rxvt.el: Require term/xterm. (rxvt-function-map): Use xterm-rxvt-function-map. (rxvt-standard-colors): Move before first use. (terminal-init-rxvt): Use xterm--push-map and xterm-register-default-colors. (rxvt-rgb-convert-to-16bit, rxvt-register-default-colors): Remove. * lisp/term/xterm.el (xterm-rxvt-function-map): New var. Move shared bindings between rxvt and xterm to it. (xterm-function-map): Use it. Move the xterm-paste binding to xterm-rxvt-function-map (bug#20444). (xterm-standard-colors): Move before first use. (xterm--push-map): New function. (xterm-register-default-colors): Take standard colors as argument. (terminal-init-xterm): Use it. Adjust call to xterm-register-default-colors.
