Fixes #686 except for a false positive (bug?) in the nilness tool.

db, err := dsql.Open("mysql", connString(c.user, ""))
req.NoError(err)
_, err = db.Query(c.query)
db, e := dsql.Open("mysql", connString(c.user, ""))

To shut up go vet about shadowing err in the enclosing context.

Then you can do

var db *sql.DB
db, err = dsql.Open(yada yada)

var db *dsql.DB actually. It's one line more, but ok, err is certainly more easy to human-parse than just e.

@juanjux could you review again all the error variable names?

@ajnavarro check the last commit (I'll rebase it later), I've renamed most of the es but for a couple cases in catalog.go and resolved_table.go where the enclosing error variable is being used later with a value from in the current context and thus we either keep the e or the warning (and the danger of somebody not typing := and overwriting the enclosing one on a refactor).

@ajnavarro ajnavarro merged commit edd578f into src-d:master Apr 24, 2019
