instead of keeping around a (slow!) hashtable of markers around, use
invisible cookies with the docid at the beginning of each header, and search
for those.

etc. a buffer. From the docstring:
"What do to when user leaves the headers view (e.g. quit or doing
a new search). Value is one of the following symbols:
- ask (ask the user whether to ignore the marks)
- apply (automatically apply the marks before doing anything else)
- ignore (automatically ignore the marks without asking)."
the new mu4e-handle-marks uses this.
- org-mu4e.el: add "mu4e:"-link type and handlers to org-mode
- Makefile.am: add org-mu4e.el to package
- mu4e-hdrs.el: register handler functions for server data *outside* header
mode, so they can be used independently (and we can link to messages even
when mu4e is not active already)
- mu4e-view.el, mu-server.1, mu-proc.el, mu-cmd-server.c: support viewing
messages by msgid (rather than only by docid); document it
