Does INSERT, then SELECT on the inserted rows (in-memory database).
The purpose of all these is to cause activity so there will be trace
messages to display. Trace message formatting is included
(a useful format, with explanations).
This fixes the problem where when building with gccgo, sqlite3.c is
overwritten, leading to a build failure.
An alternative would have been to move sqlite3*.{c,h} to a subdirectory,
but that seems to confuse the linker a fair bit and would just swap one
implementation-dependent issue for another.
Closes#20
