This is a bit different than n_d_{open,create}_with_config, since
there are several non-zero status codes where we do want to return a
non-NULL database structure.
This code previously relied on _finish_open to free the notmuch struct
on errors (except for the case of database == NULL, which was a
potential double free). When we removed those frees from _finish_open,
we introduced a (small) memory leak.
In this commit, fix the memory leak, and harmonize the on-error
behaviour with n_d_open_with_config.
During refactoring for 0.32, the code that set notmuch=NULL on various
errors was moved into _finish_open. This meant that the the code which
relied on that to set *database to NULL on error was no longer
correct. It also introduced a potential double free, since the notmuch
struct was deallocated inside _finish_open (via n_d_destroy).
In this commit we revert to "allocator frees", and leave any cleanup
to the caller of _finish_open. This allows us to get back the
behaviour of setting *database to NULL with a small change. Other
callers of _finish_open will need free notmuch on errors.
The documentation claims that the database will be set to NULL in this
case, but it is currently not happening. Based on a reproducer [1]
from Austin Ray.

In order to make it easier to keep the whitespace consistent in the
configure script, use the same style defined in devel/STYLE for
C/C++.
Specifically, a line should begin with zero or more tabs followed
by fewer than eight spaces.
Presumably this will be no more difficult for people editing configure
than for people editing the C and C++ code.
'check-notmuch-commit' is an updated version of a script I have been
using (although not always as consistently as I should) before sending
patches to the list.
Although it requires a bit more tooling, encouraging people to use
check-notmuch-commit might reduce the number of round trips to the
list for style nitpicks.
As discussed at [1] we have received reports that the implicit check
using cffi.FFI().verify() is not reliable in all environments. Since
we already use pkg-config, and the python dev package should include a
.pc file [2], add an extra check using pkg-config. On at least
Debian, we have to know which version of python dev files with are
looking for, so calculate that first.

As reported in id:87h7pxiek3.fsf@tethera.net, the previous version of
the test is flaky. There is some so-far undebugged interaction between
openssl and gpgsm that causes the keys to fail to import. As a
potential workaround, use the key as exported by gpgsm, and eliminate
openssl from this particular pipeline.
New customizable variable, notmuch-tree-thread-symbols, that allows
tweaking of how trees in a forest are represented. For instance, one
can now choose to use an hyphen rather than a white space as a prefix,
or replace the character(s) used to draw arrows.

As with notmuch--process-lines, initial purpose is to provide a safe
binding for default-directory. This is enough to make notmuch-hello
robust against non-existent or corrupt values default-directory, but
probably not other views.
Initially just set the working directory, to avoid (the implicit)
call-process crashing when the default-directory points to a
non-existent location.
Use of a macro here is over-engineering for this change, but the same
change needs to be applied to several other process creation
primitives.
Because of the way emacs reports errors, a test form can crash and not
change the main buffer. To work around this, capture both signalled
errors and any other messages.
As discussed in the thread starting at [1], the fully qualified domain
name is a bit tricky to get reproducibly, might reveal information
people prefer to keep private, and somewhat unlikely to provide
reliable mail routing.
The new approach of $current_username@localhost is better for the
first two considerations, and probably at least as good as a test mail
address.

Add the function notmuch-test-result-flags to test-lib.el to avoid
repeating it in 3 T*.sh files.
