notmuch-emacs-mua: avoid extra separators at the end of the line

This used to be fine, but with recent emacs mm, trying to send the

lib/string_map: simulate stable sorting
qsort(3) does not promise stability, and recent versions of glibc have

breakage due to changing output order for message properties.
We provide a sorting order of (key,value) pairs that _looks_ stable by
breaking ties based on value if keys are equal. Internally there may
be some instability in the case of duplicate (key,value) pairs, but it
should not be observable via the iterator API.

lib: replace some uses of Query::MatchAll with a thread-safe alternative
This replaces two instances of Xapian::Query::MatchAll with the
equivalent but thread-safe alternative Xapian::Query(std::string()).
Xapian::Query::MatchAll maintains an internal pointer to a refcounted
Xapian::Internal::QueryTerm.
None of this is thread-safe but that wouldn't be an issue if
Xapian::Query::MatchAll wasn't static. Because it's static, the
refcounting goes awry when Notmuch is called from multiple threads.
This is actually documented by Xapian:
https://github.com/xapian/xapian/blob/4715de3a9fcee741587439dc3cc1d2ff01ffeaf2/xapian-core/include/xapian/query.h#L65
While static, Xapian::Query::MatchNothing is safe because it doesn't
maintain an internal object and as such, doesn't use references.
Two best-effort tests making use of TSan were added to showcase the
issue (I couldn't figure out a way to deterministically reproduce it
without making an unmaintainable mess).
First, when two databases are created in parallel, a query that uses
Xapian::Query::MatchAll is made (lib/query.cc), resulting in the
following backtrace on a segfault:
