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

Signed-off-by: Benoit Sigoure <tsunanet@gmail.com>
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.
Fix check_tsd -v when IPv6 is used.
Fix coding style a bit in tsd_check.

Mostly prevent lines from being longer than 80 columns and remove some
unnecessary cruft when parsing command-line arguments.  This change is
mostly a no-op.
Properly parse floating point values in scientific notations.

They do not always contain a period.  So check also for an 'e'
in lower or upper case.

Cache auto-completion results even if we don't use them.
Don't leak scanners when fetching suggestions from HBase.
Fetch the correct number of suggestions from HBase.

This bug had a subtle side-effect: the `break' in the while loop
was actually nested in a `for' loop, and was only breaking out of
the `for' loop, which had the weird consequence that we'd scan the
first 25 results from HBase, then because of the incorrect check
we'd iterate once more, get one more row from the next batch of
rows, then break out of the `for' loop, scan more rows, get the
first one in that batch, break out again, and so on and so forth
until the scanner reached the end key (generally rather quickly
given how the end key is crafted).

The net result is that we'd return the first 25 suggestions,
followed by 1 out of every 25 subsequent suggestion until the
end key.  This could confuse the web UI, as it relies on the
last suggestion returned to know whether to scan more.

This closes #63.
