30ec86a81e 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.

d795a7a3ba core: introduce pseudo program with pragma 
Introduced pragma statement parsing and update in memory of default page cache size.

There are some more "improvements" to the print insn procedure —  I couldn't decide what was the preferred way in rust to do printing on different int types so I went with the stupidest I could think of at the moment.
