v1 flexible database location

This adds support for split mail / database location, and fallback to
XDG consistent database location. There are quite a few code paths to
test, and several more tests are most likely needed.

This applies on top of the series at id:[hidden email].

[PATCH 1/5] lib/open: support NOTMUCH_DATABASE environment variable

The additional code is trivial, but making sure we get the priority of
various options correct takes a few tests.

[PATCH 2/5] support splitting mail from database location.

In reply to this post by David Bremner-2
Introduce a new configuration value for the mail root, and use it in
preference to the database.path (which previously implied the mail was
also in this location.

[PATCH 3/5] lib/open: move path calculations after notmuch object creation

In reply to this post by David Bremner-2
This is just code movement. A future commit will need the notmuch
object to exist for the path manipulation.

[PATCH 4/5] lib/open: open xapian database without .notmuch prefix.

In reply to this post by David Bremner-2
In a split configuration, it does not make sense to have the extra
.notmuch/ directory. Leave the xapian/ level of the path to allow the
use of the top level e.g. as a place to store backups as is currently
done by upgrade code in notmuch-new.

[PATCH 5/5] lib/open: support XDG_DATA_HOME as a fallback database location.

In reply to this post by David Bremner-2
This changes some error reporting, either intentionally by reporting
the highest level missing directory, or by side effect from looking in
XDG locations when given null database location.
