Add LithiumSR1 input/output support

This is a code drop of both DataInput and DataOutput for Sodium SR1
streaming format. It uses its own dedicated tokes, along with quite
a few of stateful encoding rules.

Where Lithium did encoding did not perform any look-behind except
for LeafSetEntryNodes and only maintained simple coding tables,
this coder maintains simple 'parent' state tracking.

While the state tracking is not mandated on the encoder side, some
amount of tracking is required in the decoder side to provide full
coverage of coding constructs.

Two examples of this are:
- parent QName references, which are expanded to cover not only
  LeafSet/LeafSetEntry, but also UnkeyedList/UnkeyedListEntry
  and most importantly Map/MapEntry pairs
- Map/MapEntry tracking is also important for coding leaf nodes
  which represent keys -- in those cases emitting the leaf value
  is superfluous, as it can be looked up from MapEntry's predicates

Also this state tracking is maintained on-stack, thus making issues
related with it nigh impossible (unlike the Lithium LeafSetEntry

Robert Varga [Fri, 20 Sep 2019 08:07:10 +0000 (10:07 +0200)]
Add Magnesium encoding tokens

Changes to how uint8/16/32/64 types are mapped results in the need
to transfer the new value types. These represent 4 brand new tokens,
which need to be handled.

One option would be to fork NeonSR2 and modify it, somehow dealing
with value lookups (i.e. Uint8 is not valid in SR2 stream, but tokens
are shared across Lithium/NeonSR).

Another option is to create a streaming format from scratch, coming
up with a completely new family of tokens and encoding rules. This
is attractive, as both current formats have three deficiencies:

1) they encode MapEntry key values twice, once in the leaf itself
   and once in the entry's NodeIdentifierWithPredicates
2) they are '0-happy', i.e. they do not recognize that integer codes
   and sizes are typically much smaller than the 4-byte range and thus
   much of the stream is just small ints encoded as 4 bytes
3) while they are simple and straighforward, they also end up wasting
   bits -- the four token families (codes, value types, node types,
   path argument types) each have at most 15 distinct values, and
   hence the bytes used to transmit them have 4 empty bits (or more)

Hence we take the other option and design a streaming format with
brand new tokens, which are structured to carry as much more
information per byte.

This is done by combining 'type' information with forward coding
hints, for example:

- a Boolean leaf value would previously require 2 bytes:
    (byte)    ValueTypes.BOOL_TYPE
    (byte)    true/falseIn the new tokens
  whereas new tokens express this in one byte:
    (byte)    LeafValue.BOOLEAN_{FALSE,TRUE}
- a byte[5] value would require 10 bytes to encode:
    (byte)    ValueTypes.BINARY_TYPE
    (int)     length
    (5 bytes) bytes
  whereas new tokens express this in 6 bytes:
    (byte)    ValueTypes.BINARY_0 + 5 (works up to 127)
    (5 bytes) bytes

A similar approach is taken when encoding NormalizedNode types. Here
we recognize there are only 14 node types (currently) and hence we
can provide up to 4 additional bits for information about how the
node's identifier is encoded.

For PathArguments, we also use separate coding, where the format
is flexible based on the 4 types on identifiers there are, each
having slightly different format. Most notable here is the integration
of QName reference coding (for normal PathArguments) and integrated
set size coding (for AugmentationIdentifiers).

This this patch adds just the token definitions, along with basic
documentation and version declaration.
