SQLite page table

[sholsapp]

I want to add a user-space page table to a heap layer (probably the source heap) that is backed with a SQLite in-memory database backed with a custom fixed region memory allocator.

I think it makes sense to embed the SQLite amalgamation in our source code base. Some starting points following:

• Some instructions for compiling this code is at http://www.sqlite.org/cgi/src/doc/trunk/README.md and works on OSX.
• Some instructions for swapping out the dynamic memory allocator for SQLite is at http://www.sqlite.org/malloc.html
