decode: More type safe API and split scalar into multiple types

Browse Source 
Preparation to make decoder use less memory and API more type safe.
Now each scalar type has it's own struct type so it can store different
things and enables to have a scalar interface.
Also own types will enable experimenting with decode DLS designs like
using chained methods that are type aware.

- Actual value. Decoded value represented using a go type like `uint64`, `string` etc. For example a value reader by a utf8 or utf16 reader both will ends up as a `string`.
- Symbolic value. Optional symbolic representation of the actual value. For example a `scalar.UToSymStr` would map an actual `uint64` to a symbolic `string`.
- Symbolic value. Optional symbolic representation of the actual value. For example a `scalar.UintMapSymStr` would map an actual `uint64` to a symbolic `string`.
