fddc57d548 Use sqlite3_limit instead of hard-coded SQLITE_MAX_VARIABLE_NUMBER (#371) (#288) r=rnewman 
* Part 1: added limits feature to rusqlite dependencies.
* Part 2: replace references to SQLITE_MAX_VARIABLE_NUMBER with sqlite3_limit.
* Move assertion check for correct number of variables in repeat_values to before call as this is where the variable is defined.

7bcf311db9 Pre: move SQLValueType to core, because it's so central. 
Yes, this isn't tidy... but in order to be really tidy we'd need to
split up db into parts that don't depend on a particular SQLite library.
