Restore relative path handling for database.path

Restore relative path handling for database.path

[David Bremner]

Release 0.32 broke (at least) `notmuch new` if database.path has a
relative value.

Although support for relative paths was undocumented, it was
introduced as an easier (to implement) alternative to ~
expansion. Restore the pre-0.32 functionality, and treat path config
items introduced in 0.32 consistently.

[PATCH 1/9] test: add known broken test for relative database path in new

[David Bremner]

This test highlights a bug introduced in 0.32. The new split between
path and mail_root does not properly canonicalize relative paths in
the latter.

[PATCH 2/9] lib/config: canonicalize paths relative to $HOME.

[David Bremner]

Prior to 0.32, notmuch had the (undocumented) behaviour that it
expanded a relative value of database.path with respect to $HOME. In
0.32 this was special cased for database.path but broken for
database.mail_root, which causes problems for at least notmuch-new
when database.path is set to a relative path.

The change in T030-config.sh reflects a user visible, but hopefully
harmless behaviour change; the expanded form of the paths will now be
printed by notmuch config.

check val[0] first then one does not need to waste time scanning
through all the other possible values for 'key'. that is trivial
"optimization", other possible but not worth the effort...

Forget this suggestion; changing order makes things worse -- probably
in values of other keys than these checked don't start with '/' so
there would be one extra check in most of the cases...

(if it existed, one notices when it fails (or not, we don't fail on error
:/ -- anyway noise to terminal/log (hopefully)

Maybe "presumed" rather than "expanded"?

This series has been applied to release and master

I'm still waiting for feedback on the tag-hook patch and the $HOME/mail
