util/collate: remove CollatorOption ( #15472 )
...
`CollatorOption` was used to specify the `PadLen` which aims to support
"PADDING" attribute of the collations. But now it is not needed anymore,
since TiDB actually implements "PADDING" by removing trailing spaces.

expression: add builtin function WEIGHT_STRING() ( #14792 )
...
Add builtin-function WEIGHT_STRING(). MySQL manual described most of its behavior except:
If the input str is of numeric types, WEIGHT_STRING() in MySQL returns NULL, so does this implementation.
If the input str is of other types rather than string or numeric, the result of WEIGHT_STRING() in MySQL is not cleared. I simply evaluated the input as string.

We import "github.com/pkg/errors" in the code, and actually put
the "github.com/pingcap/errors" there in the vendor path.
That's a dirty hack, and prevent the introduce of Go module.
