Emit long string values without truncation

Browse source 
There are few long options (`bin_shards` and `slab_sizes` for example)
when they are specified and we emit statistics value gets truncated.

Moved emitting logic for strings into separate `emitter_emit_str`
function. It will try to emit string same way as before and if value is
too long will fallback emiting rest partially with chunks of `BUF_SIZE`.

Justification for long strings (longer than `BUF_SIZE`) is not
supported.
