      fmt: unify array and slice formatting for bytes and other types · 9149aa10
      Martin Möhrmann authored 
      Make verbs b,c,o and U work for any array and slice of integer
type including byte and uint8.

Fix a bug that triggers badverb for []uint8 and []byte type
on the slice/array level instead of on each element like for
any other slice or array type.

Add tests that make sure we do not accidentally alter the
behavior of printing []byte for []byte and []uint8 type
if they are used at the top level when formatting with %#v.

      fmt: cleanup reflect value handling · d170d3ed
      Martin Möhrmann authored 
      Merge printReflectValue into printValue. Determine if handleMethods
was already called in printArg by checking if depth is 0. Do not
call handleMethods on depth 0 again in printValue to not introduce
a performance regression. handleMethods is called already in printArg
to not introduce a performance penalty for top-level Stringer,
GoStringer, Errors and Formatters by using reflect.ValueOf on them
just to retrieve them again as interface{} values in printValue.

Clear p.arg in printValue after handleMethods to print the type
of the value inside the reflect.Value when a bad verb is encountered
on the top level instead of printing "reflect.Value=" as the type of
the argument. This also fixes a bug that incorrectly prints the
whole map instead of just the value for a key if the returned value
by the map for the key is an invalid reflect value.
