    Merge branch 'ff/statsd'

commit 73918b4759930c3420b8082342847e92a0cb44c5
Author: Florian Forster <octo at collectd.org>
Date:   Fri Jul 26 15:18:43 2013 +0200

    stats plugin: Don't check the value of '(value_t).derive'.
    
    statsd_parse_value() will write to (value_t).gauge, so don't read from another
    member of the union. This also fixes problems with counter values being zero,
    for whatever that is supposed to be useful for.
    
    Github: #358

commit e51085e108c2ac63da82d042e22d26964dfe79cd
Author: Florian Forster <octo at collectd.org>

    statsd plugin: Store values internally as double.
    
    While the documentation states that "values should generally be integers", this
    "should" is not taken in the strict RFC meaning. For compatibility with Etsy's
    statsd, handle everything as a double up until the last possible moment.

commit 4ebf0ce945b6ad1f8852aeb13d86a6f0a6144501
Author: Florian Forster <octo at collectd.org>
Date:   Thu Jul 11 14:58:32 2013 +0200

    statsd plugin: Make metric names case-sensitive.
    
    The StatsD by etsy is case sensitive, so we should do the same. Also, strcmp()
    should have better performance than strcasecmp().

commit 57fcbb129aa789857f5028a5195f1e23f444a58a
Author: Florian Forster <octo at collectd.org>

    statsd plugin: Don't use strtok_r() to split multi-metric packets.
    
    Profiling has shown that it is one of the bottle-necks.

commit f234b329b148bd1203ea2b68110d85766e6615f7
Author: Florian Forster <octo at collectd.org>
Date:   Thu Jul 11 13:03:12 2013 +0200

    statsd plugin: Dont'a call common.c:parse_value().
    
    parse_value() is doing a strdup() do it can remove trailing whitespace.
    We don't need that for the statsd protocol, so we just call strtoull()
    instead, improving performance but a couple of percent again.

commit 74f51aa494578a5b1cbd8a93597374c62db39640
Author: Florian Forster <octo at collectd.org>
Date:   Thu Jul 11 10:12:54 2013 +0200

    statsd plugin: Avoid calling snprintf() in the hot path.
    
    snprintf() is very expensive and the alternative is simple. This shaves
    off about 7% of the time spent handling events.

commit acc226d722bf3d4d06ff49f93f2bed27aec3aec6
Author: Florian Forster <octo at collectd.org>
Date:   Thu Jul 11 10:11:14 2013 +0200

    statsd plugin: Remove the prefix in the counter and gauge handlers.
    
    The prefix is added in statsd_metric_lookup_unsafe(), so we don't need
    to do this here anymore. Since snprintf() is expensive, this increases
    performance considerably.

Date:   Mon Jun 17 15:15:55 2013 +0200

    statsd plugin: Allow several metrics with the same name but different types.
    
    This more closely mimicks Etsy's implementation.
