Bryan Boreham d51a5344cd labels: new version de-duplicating strings in SymbolTables 
The individual strings for label names and values are held in a table,
and each Labels value is a run of varint-encoded indexes into that table.

When creating new labels, a sync.Mutex is locked around reads and writes.
When reading labels, there is no locking because the table of strings
used by those labels is immutable.
