[notmuch] [PATCH] notmuch-show-get-header: new function; return alist of parsed header fields.

This function parses the displayed message to recover header fields. It uses mailheader.el to do the actual header parsing, after preprocessing to remove indentation. It relies on the variables notmuch-show-message-begin-regexp, notmuch-show-header-begin-regexp, and notmuch-show-message-end-regexp
