Everytime the purge check was running, a new segment was being added.
This meant the list of almost-empty files in the HH directories would
grow continually.
If DecodeSameTypeBlock is called on on an empty Values slice, it would
panic with an index out of bounds error. This func can actually be removed
because DecodeBlock can determine what type of values are encoded already.
This will still panic if the block cannot be decoded due to other reasons.
Fixes#4365
If similar float values were encoded, the number of leading bits would
overflow the 5 available bits to store them (e.g. store 33 in 5 bits). When
decoding, the values after the overflowed value would spike to very large and
small values.
To prevent the overflow, we clamp the value to 31 which is the maximum
number of leading zero bits we can encoded.

If an aggregate derivative query did not have a value in the first
time bucket, it would abort early and return a single row with value
of 0. Similarly, if either the current or previous value was nil,
it would skip the row and not append any values causing gaps and
no data to show up.
Instead, this will append a nil value if either the current or previous
valis is nil. This essentially allows nil values to carry through the
results as well as gives a more sensible value for rows where we cannot
compute a difference (instead of dropping the row as before).

This commit changes `tsdb.mapFunc` to use `tsdb.MapInput` instead
of an iterator. This will make it easier and faster to pass blocks
of values from the new storage engine into the engine.
Without this change if hinted-handoff was disabled the service would
correctly reject writes, but it would process any data sitting in
hinted-handoff queues. With this change the service is completely
disabled.
With this change Graphite TCP connections are tracked on a per-service
basis. This allows a closing Graphite service to first shutdown any
active connections, thereby unblocking the rest of shutdowm.
This work exposed small shortcomings with the existing Diagnostics
system and that code has alse been tweaked.
