Use libnotmuch config / database search in python-cffi bindings

Use libnotmuch config / database search in python-cffi bindings

[David Bremner]

This is my first "serious" attempt at modifying the python-cffi
bindings, so I would appreciate feedback, particularly on the API changes.

In my dev branch this is applied on top the series [1] and the patch
[2].  The first is mandatory, the second might be optional, I didn't
test.

[PATCH 1/4] python-cffi: fix typos in docstring for Database.default_path

[David Bremner]

These generate warnings from sphinx doc, which makes it harder to
debug documentation changes. They also corrupt the output.

[PATCH 4/4] python-cffi: switch to notmuch_database_{open,create}_with_config

[David Bremner]

Since release 0.32, libnotmuch provides searching for database and
configuration paths. This commit changes the python module notmuch2 to
use those facilities.

This fixes the bug reported in [1], along with a couple of the
deprecation warnings in the python bindings.

Database.default_path is deprecated, since it no longer faithfully
reflects what libnotmuch is doing, and it is also no longer used in
the bindings themselves.

This commit choose the default of config=CONFIG.EMPTY (equivalent to
passing "" to notmuch_database_open_with_config).  This makes the
change upward compatible API-wise (at least as far as the test suite
verifies), but changing the default to CONFIG.SEARCH would probably be
more convenient for bindings users.

Generally this series looks good to me -- some suspicious newlines I see,
some (if not all) of those might be ok...

I usually go by what is in Debian oldstable, which is 3.7.x at this

I run nmbug using python 2.7 >;D

Last time I recall python 3.6 is the oldest supported version
(i.e. python 3.5 is EOL'd).
