lib: Expose query debug output via an environment variable
Allow query debugging to be enabled at run-time by setting the
NOTMUCH_DEBUG_QUERY environment variable to a non-empty string.
Previously, enabling query debugging required recompiling, but parsed
queries are often useful for tracking down bugs in situations where
recompiling is inconvenient.
