Fix yet another sign extension bug.

There is no code path that writes one-byte long integer values, but this
bug causes forward compatibility issues with future releases that will
write one-byte long integer values.

!@#$%^ you Java for not having `unsigned'.

Fix regression that prevents reading pre-1.0 floating point values.

Before OpenTSDB 1.0, floating point values were incorrectly encoded
when stored in HBase.  Their flags pretended they were stored on 4
bytes, but they were instead stored on 8 bytes with 4 leading zeros.
This bug got fixed in f4f405c9, with a workaround added to detect
such values and fix them automatically as part of the compaction
process.

The code contains an optimization, however, to skip the compaction
for single-KeyValue rows.  This is because if a row contains only
one KeyValue, there is obviously no point in running it through the
compaction code, since there is nothing to compact.  But because
the compaction code was the one that was transparently fixing up
those incorrectly encoded floating point values, this optimization
prevented them from getting fixed up.

So add some code to detect this case and fix up the KeyValue anyway.

There was also another bug in the code dumping time series data, where
it was also ignoring this corner case and incorrectly parsing the value.

In both cases the end result for a user is that the code would pretend
the value is 0, when in fact it's not.

Thanks to Paula Keezer for reporting the bug.

Add the ability to use mouse for drag-to-zoom on graphs.

Stop tracking mouse movements when not using the zoom box.
Add -W (downsample window) flag.

Previously if you said you wanted to downsample, it would just use
your duration (lookback) window as the downsample period.
This lets you specify either.

Don't block mouse click events on the image.

Doing so means that when the focus is on one of the text boxes,
clicking on the image doesn't remove the focus from the text box,
which is annoying as change of focus is often used to trigger an
update of the graph.

Also increase the minimum selection size to avoid unintentional
drag-to-zoom events, which happen easily with a touch pad.

Improve TSD write throughput by 10x.

This fixes an important performance bug in TSD.  The bug is triggered
when large TCP frames are handled by TSD's telnet-style decoding logic.
TSD is trying to split the input lines, however it was using a Netty
class that exhibits very poor performance for this job.  This due to
the fact Netty's DelimiterBasedFrameDecoder is built to handle multiple
delimiters (e.g. "\n" or "\r\n"), and it would always attempt to match
all delimiters to the input buffer to try to find the smallest match.

So on large input buffers, which is particularly worse when the client
is connected from localhost as the MTU of loopback interfaces tend to
be very large, the code would always attempt to look for a "\r\n" in
the entire input, thereby wasting a great deal of CPU cycles.

This code replaces Netty's DelimiterBasedFrameDecoder with a simpler
decoder that only supports splitting lines on "\n" or "\r\n" and
always works in one pass.  Single-socket throughput has been seen
to increase by as much as 20x, and overall throughput with several
clients contending for CPU time has been seen to increase around 10x.

This closes #120.
