Error code member going away #821
Description
Due to the extra work that has been needed to support consistent error code member on all platforms, which is not even the real SQL error code according to the DRAFT Web SQL API (http://www.w3.org/TR/webdatabase/), I would like remove this member from the next major release.
My plan is to actually keep the error code member set to 0 in the November 2018 major release (#773) and possibly remove it in another major release.
In exchange the actual sqlite3 error code will be included in the error message member whenever possible.
