Add sorter utility functions and opcodes
...
This adds basic in-memory sorting utility functions, similar to SQLite's
src/vdbesort.c. We need to improve this later with external sorting so
to support large data sets.
This also adds sorting functionality to the VDBE. Note that none of this
is wired to SQL translation yet so it's unused for now.
