* Standardize the error messages generated by constraint failures to a formatdrh2013-11-05

| | | | | and WITHOUT ROWID. FossilOrigin-Name: b21d831b2aa55507dd9def2acb02cdbffddf10d1
* The Index object now has nKeyCol and nColumn. nColumn is the total numberdrh2013-10-22
| | | | | | of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. FossilOrigin-Name: a106ce86cd4afd1f81603826de77df1fb25e9ab5
