[Patch v6 8/8] lib: eliminate fprintf from _notmuch_message_file_open

[David Bremner]

You may wonder why _notmuch_message_file_open_ctx has two parameters.
This is because we need sometime to use a ctx which is a
notmuch_message_t. While we could get the database from this, there is
no easy way in C to tell type we are getting.
