Avoid creating inconsistent buffer states in term-char-mode
* lisp/term.el (term-mode, term-char-mode, term-line-mode) (term-emulate-terminal): Make buffer read-only in 'term-char-mode', except for the process filter's output. Use 'read-only-mode-hook' to track and restore the user-set state of 'buffer-read-only' for 'term-line-mode'. (Bug#24837) (term-char-mode-buffer-read-only): New user option. (term-line-mode-buffer-read-only): New buffer-local variable. (term-line-mode-buffer-read-only-update): New function. (term-char-mode, term-line-mode): Use 'term-set-goto-process-mark' in pre-command-hook, and 'term-goto-process-mark-maybe' in post-command-hook to counter-act unexpected changes to point when using 'term-char-mode'. (term-char-mode-point-at-process-mark): New user option. (term-goto-process-mark): New buffer-local variable. (term-set-goto-process-mark): New function. (term-goto-process-mark-maybe): New function. (term-process-mark): New function. * etc/NEWS: Mention the new behavior and user options.
