[PATCH 0/2] lib: Allow read-only messages to be synchronized to a writable database

[Michael Forney]

In developing ner (a notmuch ui), I open a read-only database connection so I
don't interfere with other notmuch programs, but this makes it difficult to
make modifications to the tags of messages I open.

The first patch replaces the freeze/thaw functionality with a single sync
function. This way, read-only messages can be modified just as writable ones
can be, but the notmuch_message_sync operation requires a writable database
connection.

The second patch adds a function `notmuch_database_sync_message' which will
perform the synchronization using the given database (and does not care if the
modified message was opened with a read-only database).

I've attempted to make these changes in the notmuch bindings as well, but
haven't tested them.

Feedback is welcome!
