Closes #2927
Fix typo in comment
Merge branch 'daniel_2985' into next
Mark geo terms non-deterministic
Derived to_geojson_term_t from op_term_t, and undid a previous change to the op_term_t interface.
Typo
Introduced polygon_sub term to replace sub() on polygons.
Fix "verbse" typo.
Add missing JavaScript tests.
Merge branch 'daniel_3011' into next
Moved rand_string to unittest_utils.
Made parse_time not have such logger.cc-specific exception-throwing behavior.
Made directory_lock_t destructor be noexcept(false).
Fixed calls and includes in unit tests.
Removed unused functions ptr_in_byte_range and range_inside_of_byte_range.
Made remove_directory_recursive not throw an exception.  Removed remove_directory_exc_t.

Nothing was catching the exception, which seemed to know that its
own error message was for a fatal error.  Also, if we did catch
it, there would be a memory leak because we throw from inside
the callback of nftw.
Add missing contributor to release notes
