[PATCH v3 2/5] Rename the -json printer functions in notmuch-reply and notmuch-show to generic -sprinter functions.

[Peter Feigl <craven@gmx.net>]

All the structured output functions in notmuch-reply and notmuch-show
are renamed to a generic name (as they do not contain any json-specific
code anyway). This patch is a preparation to actually using the new
S-Expression sprinter in notmuch-reply and notmuch-show.
