The fields step and redoState of struct scanner are now defined as
`func(s *scanner, c byte) int` instead of
`func(s *scanner, c int) int`, since bytes are sufficient.
Further changes improve the consistency in the scanner.go file.

JSON decoding currently fails for null values bound to any type
which does implement the JSON Unmarshaler interface without checking
for null values (such as time.Time).
It also fails for types implementing the TextUnmarshaler interface.
The expected behavior of the JSON decoding engine in such case is
to process null by keeping the value unchanged without producing
any error.
Make sure null values are handled by the decoding engine itself,
and never passed to the UnmarshalText or UnmarshalJSON methods.

The "string" option only applies for strings, floats, integers, and
booleans as per the documentation. So when decoding ignore the "string"
option if the value is not of one of the types mentioned. This matches
the Marshal step which also ignores the "string" option for invalid
types.

All slice types which have elements of kind reflect.Uint8 are marshalled
into base64 for compactness. When decoding such data into a custom type
based on []byte the decoder checked the slice kind instead of the slice
element kind, so no appropriate decoder was found.
Fixed by letting the decoder check slice element kind like the encoder.
This guarantees that already encoded data can still be successfully
decoded.
Fixes#8962.

The error message for decoding a unquoted value into a struct field with
the ,string option specified has two arguments when one is needed.
Make the error message take one argument and add a test in order to cover
the case when a unquoted value is specified.
Also add error value as the missing argument for Fatalf call in test.
Fixes the following go vet reports:
decode.go:602: wrong number of args for format in Errorf call: 1 needed but 2 args
decode_test.go:1088: missing argument for Fatalf("%v"): format reads arg 1, have only 0 args
