example, a child message doesn't include a complete list of References
headers back to the beginning of the thread.
It also simplifies dealing with mapping a message ID to a thread ID
which is now a simple get_thread_id just like get_message_id, (and no
longer an iterator-based thing like get_tags).

Move read-only-archive hint from "notmuch setup" to "notmuch new"

Shuffle the value numbers around in the database.
First, it's nice that for now we don't have any users yet, so we
can make incompatible changes to the database layout like this
without causing trouble. ;-)
There are a few reasons for this change. First, we now use value 0
uniformly as a timestamp for both mail and timestamp documents, (which
lets us cleanup an ugly and fragile bare 0 in the add_value and
get_value calls in the timestamp code).
Second, I want to drop the thread value entirely, so putting it at the
end of the list means we can drop it as compatible change in the
future. (I almost want to drop the message-ID value too, but it's nice
to be able to sort on it to get diff-able output from "notmuch dump".)
But the thread value we never use as a value, (we would never sort on
it, for example). And it's totally redundant with the thread terms we
store already. So expect it to disappear soon.

Invent our own prefix values.

Split BOOLEAN_PREFIX into INTERNAL and EXTERNAL subsets.
The idea here is that only some of the prefix names (such as "id" and
"tag") actually make sense in external user-supplied query
strings. Other things like "type" are internal implementation details
of how we store things in the database. So internal machinery will add
those terms to the database and we don't need to support them in the
string itself.
With this, we can now simply loop over the external prefix values to
let the quiery parser know about them. So as we add prefixes in the
future, we'll only need to add them to this list.

Add the magic to allow searches such as "tag:inbox".
The key for this is call add_boolean_prefix on the QueryParser

make this term a requirement of the search. We're starting to have a
real system here.
Also, I didn't want to expose the ugly name of "msgid" to the user, so
we add a prefix name of simply "id" instead.

Trim down prefix list to things we are actually using.

both terms and values)).

thread ID through the reference is established. I also plan to add
actual documents to represent threads.)
