This has the the non-trivial side effect silencing all output to
stderror from these two routines.
The stdargs based infrastucture will be used in following commits for
a more general logging mechanism.
The changes to notmuch-{new,search} and test/symbol-test are just to
make the test suite pass. The fact that no other changes are needed is
probably a sign of weakness in the test suite.

The idea is to have a logging function setting this string instead of
printing to stderr.

This is a thin wrapper around the previously implemented string
logging infrastructure. In the future it could have more configurable
output options.

This is not supposed to change any functionality from an end user
point of view. Note that it will eliminate some output to stderr. The
query debugging output is left as is; it doesn't really fit with the
current primitive logging model. The remaining "bad" fprintf will need
an internal API change.

To: notmuch
You may wonder why _notmuch_message_file_open_ctx has two parameters.
This is because we need sometime to use a ctx which is a
notmuch_message_t. While we could get the database from this, there is
no easy way in C to tell type we are getting. The remaining fprintf is
removed by Jani's series un-deprecating single message mboxes.
