bookmarks: forbid \0 \r \n : in bookmark names (BC)

We restrict : to 1. make it easer to convert bookmarks to git branches,
2. use : later for a syntax to push a local bookmark to a remote bookmark
of a different name. \0, \n, \r are fobbidden they are used to separate
bookmarks in the bookmark file.

This change breaks backward compatbility as ':' was an allowed character in
previous versions.
