Fabian Reinartz a317f252b9 Expose series references to clients 
This exposes a reference number of a series represented by a label set
to clients.
Subsequent samples can be directly added via the reference rather than
repeatedly passing in the full labels. This drasitcally speeds up the
append process.

The appender chain uses different sections of the reference number for
assignment to child appenders and invalidating reference numbers as
necessary.

Clients can either pass out reference numbers themselves or have their
own optimized lookup, i.e. by directly associating unparsed metric
descriptors strings with reference numbers.

Fabian Reinartz 8c31c6e934 Make concurrent head chunk reads safe, fix misc races 
This adds a 4 sample buffer to every head chunk. The XOR
compression scheme may edit bytes in place. The minimum size
of a sample is 2 bits. So keeping the last 4 samples in an in-memory
buffer makes it safe to query the preceeding ones while samples
are added

Fabian Reinartz 300f4e2abf Use separate lock for series creation 
This uses the head block's own lock to only lock if new series were
encountered.

This changes block directory names from the int64 timestamp
to sequential numbering.

Fabian Reinartz 3f72d5d027 Fix last timestamp initialization 
This initializes the chunkDesc's last timestamp to the minimum
value so initial samples with a timestamp of 0 (e.g. in tests)
are not accidentally dropped.

Fabian Reinartz 5d75a3dc7b Add basic compaction 
This adds a basic compactor that will merge two persisted blocks into
one. It simply fully rewrites the index and concatenates the chunk
lists.

It just writes into the current working dir and doesn't properly handle
which blocks to compact for now.

Fabian Reinartz c00d17e691 Modify IndexReader API to accomodate compaction 
This changes the IndexReader API to expose plain labels
and chunk meta information instead of a Series interface.
Dropping of irrelevant chunks is moved into the querier.

A LabelIndices method is added to query for existing label
value indices.

Fabian Reinartz b08f82fa4e Pre-select relevant chunks on series access. 
This adds interval metadata to indexed chunks. The queried interval
is used to filter chunks when queried from the index to save
unnecessary accesses of the chunks file.

This is especially relevant for series that come and go often and larger
files.
