Filippo Valsorda 3d3f9f4138 cryptobyte: don't ignore bytes added to BuilderContinuations of fixed-size Builders
Builders created with NewFixedBuilder were broken when used with
BuilderContinuations. The length of the bytes written to the
continuation would get added correctly to the parent, but the actual
content would be discarded.

For example, the BytesOrPanic() in TestFixedBuilderLengthPrefixed would
return [00 08] instead of [00 08 ff ff ff ff ff ff ff ff].

Filippo Valsorda b078efbc80 cryptobyte: add (*Builder).Unwrite and (*Builder).SetError
Unwrite allows programs to rollback builders more reliably and
efficiently than by copying a Builder (which might waste an allocation
and depends on internal behavior). This is useful for example to remove
a length-prefixed field if it ends up being empty.

SetError allows simple Builder extensions to set errors without making
MarshalingValue wrappers.

Based on the experience of CL 144115.
