Bryan Boreham d84282b105 Labels: use single byte as separator - small speedup
Since `seps` is a variable, `seps[0]` has to be bounds-checked every
time. Replacing with a constant everywhere it is used skips this
overhead.

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.
