new feature: bindable functions for toggling and jumping to "bookmarks"
With the 'bookmark' function, the user can place a bookmark on any line in the buffer. Multiple lines can be bookmarked in this way. With 'prevbookmark' and 'nextbookmark', the user can then easily return to the bookmarked lines. The search for a bookmark wraps around, as if start and end of buffer are connected. [However, in this implementation, when a bookmarked line is deleted, the bookmark is deleted too. This is undesirable. Also, when such a deleted line is pasted elsewhere, the bookmark reappears with it, and when pasted multiple times, the bookmark will be there as many times. This is thoroughly undesirable. These behaviors will be changed in a later commit.] A bookmark is not yet visible in any way. This fulfills https://savannah.gnu.org/bugs/?57577.
